Abstract

We live in interesting times. Portents of impending catastrophe pervade the literature, calling us to action in the face of unmanageable volumes of scientific data. But it isn't so much data generation per se, but the systematic burial of the knowledge embodied in those data that poses the problem: there is so much information available that we simply no longer know what we know, and finding what we want is hard – too hard. The knowledge we seek is often fragmentary and disconnected, spread thinly across thousands of databases and millions of articles in thousands of journals. The intellectual energy required to search this array of data-archives, and the time and money this wastes, has led several researchers to challenge the methods by which we traditionally commit newly acquired facts and knowledge to the scientific record. We present some of these initiatives here – a whirlwind tour of recent projects to transform scholarly publishing paradigms, culminating in Utopia and the Semantic Biochemical Journal experiment. With their promises to provide new ways of interacting with the literature, and new and more powerful tools to access and extract the knowledge sequestered within it, we ask what advances they make and what obstacles to progress still exist? We explore these questions, and, as you read on, we invite you to engage in an experiment with us, a real-time test of a new technology to rescue data from the dormant pages of published documents. We ask you, please, to read the instructions carefully. The time has come: you may turn over your papers…

<abstract>
<p>We live in interesting times. Portents of impending catastrophe pervade the literature, calling us to action in the face of unmanageable volumes of scientific data. But it isn't so much data generation
<italic>per se</italic>
, but the systematic burial of the knowledge embodied in those data that poses the problem: there is so much information available that we simply no longer know what we know, and finding what we want is hard – too hard. The knowledge we seek is often fragmentary and disconnected, spread thinly across thousands of databases and millions of articles in thousands of journals. The intellectual energy required to search this array of data-archives, and the time and money this wastes, has led several researchers to challenge the methods by which we traditionally commit newly acquired facts and knowledge to the scientific record. We present some of these initiatives here – a whirlwind tour of recent projects to transform scholarly publishing paradigms, culminating in Utopia and the Semantic
<italic>Biochemical Journal</italic>
experiment. With their promises to provide new ways of interacting with the literature, and new and more powerful tools to access and extract the knowledge sequestered within it, we ask what advances they make and what obstacles to progress still exist? We explore these questions, and, as you read on, we invite you to engage in an experiment with us, a real-time test of a new technology to rescue data from the dormant pages of published documents. We ask you, please, to read the instructions carefully. The time has come: you may turn over your papers…</p>

<title>INSTRUCTIONS TO READERS</title>
<p>Before reading any further, we are going to ask you to download a piece of software. Together, as we journey through this article, we will test the software [a new PDF document reader, called Utopia Documents (UD)] in different scenarios. You are, of course, free to read on without installing the software; however, for those of you reading the PDF version of this article, seen through the lens of UD, much more functionality will be revealed and the test will become tantalizingly more interesting.</p>
<p>To install UD, please visit the abstract page for this article (at
<ext-link ext-link-type="uri" xlink:href="http://www.BiochemJ.org">www.BiochemJ.org</ext-link>
), or
<ext-link ext-link-type="uri" xlink:href="http://getutopia.com/">http://getutopia.com/</ext-link>
. The installation process is straightforward: simply follow the link to the website, and the guidance notes there will talk you through the software installation for your platform of choice.</p>
<p>Once you have successfully downloaded UD, you are ready to read on. As you do so, look out for the UD logo:
<graphic xlink:href="bic005i014.jpg" position="float"></graphic>
. This is used to draw your attention to interactive features, pinpointing where to click on particular icons. During the test, the story will unfold gradually and the interactive features will grow in complexity. We invite you to explore the increasing functionality at your leisure (for the more adventurous, full documentation is available from the installation site).</p>

<title>INTRODUCTION</title>
<p>New technologies that promise to transform our lives excite us, but often come with unanticipated side-effects. Just think about life before email, laptop computers or mobile phones and it's clear that as much as they've improved some aspects of our lives, they've made significant demands on us in others: e.g. to learn how to use yet another new gadget, to navigate yet another new interface, to cope with the daily bombardment of (often irrelevant) communications – in short, to control the technology before it controls us. Getting the balance right can be a struggle.</p>
<p>The life sciences have not been immune from these effects. Technological advances have led to the accumulation of data on a scale unthinkable only a couple of decades ago, promising to revolutionize how we ‘do’ biology and to have dramatic impacts on our understanding of such processes as gene expression, drug discovery, and the progression and treatment of disease [
<xref ref-type="bibr" rid="B1">1</xref>
,
<xref ref-type="bibr" rid="B2">2</xref>
]. Yet the metaphors of doom used to describe the phenomenal pace of data acquisition (from data floods [
<xref ref-type="bibr" rid="B3">3</xref>
], deluges [
<xref ref-type="bibr" rid="B4">4</xref>
,
<xref ref-type="bibr" rid="B5">5</xref>
], surging oceans [
<xref ref-type="bibr" rid="B6">6</xref>
] and tsunamis [
<xref ref-type="bibr" rid="B7">7</xref>
], to icebergs [
<xref ref-type="bibr" rid="B8">8</xref>
,
<xref ref-type="bibr" rid="B9">9</xref>
], avalanches [
<xref ref-type="bibr" rid="B10">10</xref>
], earthquakes [
<xref ref-type="bibr" rid="B11">11</xref>
] and explosions [
<xref ref-type="bibr" rid="B12">12</xref>
]) betray a deep concern: despite the early warnings, we appear to have been caught unprepared, and the resulting torrent of information has all but burst our databanks [
<xref ref-type="bibr" rid="B13">13</xref>
,
<xref ref-type="bibr" rid="B14">14</xref>
]. Desperate as things may seem, this is probably just a prelude to further troubles ahead, with ‘desk-top sequencing’ becoming a reality, and the latest machines delivering terabytes of data per hour. Faced with this onslaught, standard laboratory information-management systems will be unable to cope, a situation that has been likened to “taking a drink from a fire hose” [
<xref ref-type="bibr" rid="B5">5</xref>
].</p>
<p>Beyond the information-management headaches [
<xref ref-type="bibr" rid="B8">8</xref>
] and nightmares [
<xref ref-type="bibr" rid="B15">15</xref>
], however, lies a deeper problem. Merely increasing the amounts of information we collect does not in itself bestow an increase in knowledge. For information to be usable, it must be stored and organized in ways that allow us to access it, to analyse it, to annotate it and to relate it to other information; only then can we begin to understand what it means; only with the acquisition of meaning do we acquire knowledge. The real problem is that we have failed to store and organize much of the rapidly accumulating information (whether in databases or documents) in rigorous, principled ways, so that finding what we want and understanding what's already known become exhausting, frustrating, stressful [
<xref ref-type="bibr" rid="B7">7</xref>
] and increasingly costly experiences.</p>
<p>Let's consider, for a moment, an activity for which these problems have become especially acute – the annotation of biological data for deposition in a database. There are now probably thousands of bio-databases around the world. One of the best known of these is Swiss-Prot [
<xref ref-type="bibr" rid="B16">16</xref>
], the manually annotated component of UniProtKB [
<xref ref-type="bibr" rid="B17">17</xref>
]. By contrast with UniProtKB, which currently contains more than 9 million entries, Swiss-Prot will soon contain 500000 protein sequences, of which around half have been annotated by a team of curators that has devoted 600 person years to the task over a 23 year period [
<xref ref-type="bibr" rid="B18">18</xref>
] – an incredible human effort. They achieved this by reading thousands of articles and visiting hundreds of other databases, and carefully distilling out Swiss-Prot-relevant facts. The difficulties faced by the curators are legion: with something like 25000 (increasingly specialist [
<xref ref-type="bibr" rid="B19">19</xref>
]) peer-reviewed journals publishing around 2.5 million articles each year, in the life sciences alone this effectively equates to two new papers appearing in Medline each minute [
<xref ref-type="bibr" rid="B20">20</xref>
] (see
<xref ref-type="fig" rid="F1">Figure 1</xref>
). It is consequently both impossible to keep up with developments, and progressively more difficult either to find pertinent papers or to locate new facts within them. Each newly published paper is thus now cast adrift and essentially lost at sea. Little wonder that Bairoch should lament, “It is quite depressive to think that we are spending millions in grants for people to perform experiments, produce new knowledge, hide this knowledge in a often badly written text and then spend some more millions trying to second guess what the authors really did and found” [
<xref ref-type="bibr" rid="B18">18</xref>
].</p>

</fig>
<p>The tasks of curators would not be quite so daunting were it possible to connect easily from articles to their underlying data-sets. True, supplementary data are more commonly being made available with publications, but this is usually a supporting subset rather than all the experimental data: journals simply do not have the capacity to archive all research data described in the articles they publish, and universities are only now beginning to consider the practicalities of how they might undertake this task themselves. For now, then, navigating between data and published descriptions of these data remains a formidable challenge, because the data are arriving in an “unorganized, uncontrolled and incoherent cacophony… None of it is easily related, none of it comes with any organizational methodology… [and the data are being] produced at greater and greater speed… Faster and faster, more and more and more”; and the truth is, without structure, data are mere babble [
<xref ref-type="bibr" rid="B7">7</xref>
].</p>
<p>The crux of the problem is the lack of organizational principles. The failure of online databases to interoperate seamlessly with each other, and with the literature, is ultimately a matter of standards, or lack of them [
<xref ref-type="bibr" rid="B21">21</xref>
,
<xref ref-type="bibr" rid="B22">22</xref>
]. Online databases, and online journals, were designed to be accessed by humans, not by machines; but the proliferation of databases and journals now makes the need for efficient machine-access imperative. If databases had standard interfaces and standard methods for scripts to access their contents, many of the problems of gathering and integrating information from diverse sources would evaporate [
<xref ref-type="bibr" rid="B23">23</xref>
].</p>
<p>On the other hand, contributing to the problems is the state of the literature itself. In the wake of organism-specific gene-naming cultures, the post-genomic literature descended into nomenclature chaos: faced with the task of rationalizing gene names across organisms, the amusement value of names like ken, T-shirt, hedgehog, cap ‘n’ collar, and so on, palls. It is precisely this kind of mess that spurred projects to develop meaningful ontologies [
<xref ref-type="bibr" rid="B24">24</xref>
<xref ref-type="bibr" rid="B31">31</xref>
] to help standardize how we describe biological entities. Coupled with standard, structured approaches for marking up journal articles, the fruits of these painstaking endeavours could, in future, position us to link articles not only to each other, but also to databases and other online resources [
<xref ref-type="bibr" rid="B11">11</xref>
]. The importance of being earnest in our approaches to such problems, in the way we think about our data, in the way we organize our data, and in the way we write about our data, is crucial if we are to make sense of the complexities [
<xref ref-type="bibr" rid="B32">32</xref>
]. Without such approaches, our literature is in danger of giving way to yet more of what Kerr has described as “touchy-feely text and psychobabble” [
<xref ref-type="bibr" rid="B33">33</xref>
].</p>
<p>It is clear that scientific articles could become much better conduits for the publication of research data [
<xref ref-type="bibr" rid="B34">34</xref>
,
<xref ref-type="bibr" rid="B35">35</xref>
]. Indeed, it has been argued that the distinction between an online paper and a database is already diminishing [
<xref ref-type="bibr" rid="B36">36</xref>
]. Nevertheless, much more needs to be done to make the data contained in research articles more machine-readable, a sentiment endorsed in the 2007 Brussels declaration on Scientific, Technical and Medical (STM) publishing (
<ext-link ext-link-type="uri" xlink:href="http://www.stm-assoc.org/public_affairs_brussels_declaration.php">http://www.stm-assoc.org/public_affairs_brussels_declaration.php</ext-link>
), which commits STM publishers to “change and innovation that will make science more effective.” This commitment will challenge publishers to embrace all the potential of modern Web(2.0) technologies, including blogs, wikis, Really Simple Syndication (RSS) feeds and so on [
<xref ref-type="bibr" rid="B11">11</xref>
,
<xref ref-type="bibr" rid="B37">37</xref>
<xref ref-type="bibr" rid="B39">39</xref>
], ultimately to provide more lively, interactive access to their content, and to save our journals from becoming incurably dull [
<xref ref-type="bibr" rid="B40">40</xref>
]. “The time has come,” as O'Donnell asserts, “to grab back our ‘literature’ and for editors to restore journals to their readers” [
<xref ref-type="bibr" rid="B41">41</xref>
]!</p>
<p>In the present review, we examine some recent initiatives to make published biomedical texts more machine-readable, and hence more dynamic, interesting and informative. In particular, we outline a variety of projects involving academic-journal collaborations: these are the first seedlings of much-needed community–publisher engagement, which we hope will blossom into more and wider alliances to tackle the very difficult problems involved. We also introduce a new development with Portland Press Limited, the so-called Semantic
<italic>Biochemical Journal</italic>
(
<italic>BJ</italic>
) experiment, illustrating how much can be achieved through appropriate collaboration, yet recognizing how much remains to be done. Reflecting on the considerable opportunities that lie ahead, we conclude with an international call to arms to embrace the future of digital publishing together.</p>

<title>GRABBING BACK OUR LITERATURE</title>
<p>In the sections that follow, we examine a variety of projects that challenge us to change the way we think about the scholarly literature, and to embrace new ways of interacting with it. These projects promise to transform how we access and extract the knowledge embedded in scientific articles. We discuss the advances that have been made, some of the problems these approaches help to solve, and the obstacles to progress that still exist.</p>
<sec>
<title>Ontologies for biomedical literature</title>
<p>To formalize how we describe biological entities and convert published biomedical information into machine-readable data, accessible to search engines and to algorithmic processing, several groups have developed ontologies and controlled vocabularies for biomedical texts: these are now numerous, but include, for example, the RNA Ontology [
<xref ref-type="bibr" rid="B26">26</xref>
], the Sequence Ontology [
<xref ref-type="bibr" rid="B25">25</xref>
], the Cell Ontology [
<xref ref-type="bibr" rid="B27">27</xref>
], the Systems Biology Ontology [
<xref ref-type="bibr" rid="B30">30</xref>
] and, probably the best known, the Gene Ontology (GO) [
<xref ref-type="bibr" rid="B24">24</xref>
]. To bring order to these proliferating initiatives, and better support biomedical data annotation and integration, the Open Biomedical Ontologies (OBO) Foundry was set up to unify these diverse resources [
<xref ref-type="bibr" rid="B28">28</xref>
].</p>
<p>Building on these endeavours, various Web-based tools have been developed to render such machine-readable information more generally useful to the community. One of the broadest of these, COHSE (Conceptual Open Hypermedia Services Environment) runs as a portlet: this allows users to select an ontology, then adds relevant hyperlinks to target pages (see
<xref ref-type="fig" rid="F2">Figure 2</xref>
), matching the ontology terms to those pages and propagating links to further pages [
<xref ref-type="bibr" rid="B42">42</xref>
,
<xref ref-type="bibr" rid="B43">43</xref>
]. Extensions to COHSE (including text-mining components to improve linking opportunities, and integration of workflows and services as possible link targets) are planned, but the current public version provides relatively limited functionality and is not yet sufficiently mature for some practical applications – for instance, it does not allow direct navigation to specific data (such as biomolecular sequences) via its life-science ontologies [
<xref ref-type="bibr" rid="B44">44</xref>
].</p>

<graphic xlink:href="bic005i002"></graphic>
</fig>
<p>The long-term vision of projects like this, and of the OBO Foundry in particular, is that all biomedical research data should ultimately form a single, consistent, machine-accessible whole (see also
<ext-link ext-link-type="uri" xlink:href="http://www.bio2rdf.org">http://www.bio2rdf.org</ext-link>
). Realizing this goal will not be easy: the challenge will be to provide sufficient flexibility for scientific advances to flourish within a sufficiently robust and principled framework for unification to be feasible.</p>

<title>Blogs for biomedical science</title>
<p>In recent years, ‘web logging’ (blogging) has emerged as a widespread social phenomenon. With >100 million blogs on the Internet, and a new blog appearing every half second, blogging is now recognized as a vehicle of unprecedented power for information dissemination [
<xref ref-type="bibr" rid="B46">46</xref>
]. The scientific community is in the process of catching up with these developments, and there are now ~1200 blogs dedicated to scientists and their conversations.</p>
<p>Against this background, publishers have begun to appreciate the potential of blogs to engage more interactively with their readers, to promote discussion of their journal content and to stimulate peer review. Consequently, many of the major journals now have their own blogs; some have several. Notable here is the series of blogs from Nature Publishing Group, including: Nascent, Indigenus, Methagora, Nautilus, Spoonful of Medicine, The Sceptical Chymist, The Great Beyond, The Niche, The Seven Stones and others.</p>
<p>The proliferation of the
<italic>Nature</italic>
blogs is a testament to the popularity of this medium for discussing and advancing science. Some journal blogs are doing less well, however, and attract little or no traffic. With so many to choose from, the problem is partly in knowing that a particular blog exists and partly in knowing which are the most worthwhile to read; other barriers to take-up include the activation energy required to visit individual blogs on a regular basis, and the disruption this causes to researchers' work patterns. Nevertheless, blogging has clearly captured the imaginations of hundreds of scientists and, as the ‘blogosphere’ becomes noisier, it is likely to need increasingly artful hooks to seduce the research community to engage with it more meaningfully.</p>
</sec>

<title>Project Prospect and the Royal Society of Chemistry</title>
<p>With Project Prospect, the Royal Society of Chemistry (RSC) has played a pioneering role in introducing meaning (semantics) to published content [
<xref ref-type="bibr" rid="B47">47</xref>
] and creating computer-readable chemistry. Some of their journals, such as
<italic>Organic and Biomolecular Chemistry</italic>
and
<italic>Molecular BioSystems</italic>
, now offer enhanced HyperText Mark-up Language (HTML) versions of articles, marked up by their editors using the Prospect software. Accessed via a tool-box (the ghostly silhouette on the right-hand side of the article in
<xref ref-type="fig" rid="F3">Figure 3</xref>
), features available for mark-up include compound names, bio- and chemical-ontology terms, and terms from the Gold Book [the International Union of Pure and Applied Chemistry (IUPAC) Compendium of Chemical Terminology] – marked-up terms appear as colour-coded highlights within the text. Clicking on the highlights provides relevant definitions from the Gold Book or from the Gene [

<p>Prospect mark-up significantly enriches RSC journal articles, making navigation to additional information trivial and increasing the appeal to readers, but this is just a start. More work is needed to extend the scope of the work to other subject areas, to include more extensive linking (e.g. to databases and experimental data) and to add other Prospect services. The system is currently limited to HTML, and it will be interesting to see how readily the project principles can be extended to the rest of RSC's journals and to its [Portable Document Format (PDF)] e-book collection.</p>

<p>The
<italic>ChemSpider Journal of Chemistry</italic>
is another experiment set up to demonstrate the added value that Web technologies can offer in terms of enriching published information. The Journal spans a range of chemistry-related subjects, including chemical biology, chemo-informatics and molecular modelling. Its articles are marked up using the Chemistry Markup And Nomenclature Transformation Integrated System, ChemMantis. ChemMantis identifies and extracts chemical names, converting them into chemical structures using name-to-structure conversion algorithms and dictionary look-ups in the ChemSpider chemistry database (which provides access to almost 21.5 million unique chemical entities); it also marks up a range of other chemical entities, including chemical families, groups, elements and reaction types; where appropriate, the terms are linked to their Wikipedia definitions (see
<xref ref-type="fig" rid="F4">Figure 4</xref>

<title>The
<italic>FEBS Letters</italic>
experiment</title>
<p>The
<italic>FEBS Letters</italic>
experiment was a pilot collaborative study involving the journal editors, an initial small group of authors and the curators of the MINT interaction database [
<xref ref-type="bibr" rid="B50">50</xref>
]. The broad aim here was to integrate data published in scientific articles with information stored in databases [
<xref ref-type="bibr" rid="B51">51</xref>
], but with a pragmatic focus on protein–protein interactions and post-translational modifications (PTMs); making all published biological data instantly machine-readable was clearly not possible [
<xref ref-type="bibr" rid="B52">52</xref>
]. The experiment hinged on adopting the concept of the Structured Digital Abstract (SDA). The idea of the SDA is simply to provide a mechanism for capturing an article's key facts in a machine-readable, eXtensible Mark-up Language (XML)-coded summary, in order to make them accessible to text-mining tools [
<xref ref-type="bibr" rid="B21">21</xref>
].</p>
<p>For the purpose of this experiment, key protein interaction and PTM data were collected from authors via an Excel spreadsheet and structured so as to include: descriptions of the nature of the experimental evidence; characteristics of the participating protein partners; details of the biological roles of proteins in the interactions; expression levels; the PTMs required for interaction, or that result from it; unique protein identifiers with links to MINT and UniProtKB [
<xref ref-type="bibr" rid="B17">17</xref>
]; definitions drawn from the Human Proteome Organization (HUPO) Proteomics Standards Initiative's Molecular Interaction Controlled Vocabulary; and so on [
<xref ref-type="bibr" rid="B53">53</xref>
] – a typical SDA is shown in
<xref ref-type="fig" rid="F5">Figure 5</xref>
. By the nature of the project, the parameters of the experiment were well-defined, and most of the captured relationships point to MINT entries; were it to be widely adopted, however, the system has been designed to readily generalize to other databases of protein interactions or other biological relationships.</p>

The authors of only five of these papers chose to participate, most of whom had relatively few problems with the SDA and required minimal assistance; but one author had major difficulties and needed substantial help from the MINT curators to complete the spreadsheet. During the next 10 months, to February 2009, SDAs appeared in 90

papers [
<xref ref-type="bibr" rid="B34">34</xref>

<title>PubMed Central and BioLit</title>
<p>BioLit is a suite of open-source tools designed to integrate open literature with biological databases [
<xref ref-type="bibr" rid="B55">55</xref>
]. As a proof-of-concept, the tools have been implemented using a subset of papers from PubMed Central (PMC), structural data from the Protein Data Bank (PDB) [
<xref ref-type="bibr" rid="B56">56</xref>
], and terms from various biomedical ontologies.</p>
<p>BioLit allows full-text (or excerpts of full-text) articles to be included directly in a database, and permits metadata (PDB identifiers and GO terms) to be added to such articles. The system works by mining the full text for terms of interest, indexing the terms identified, and delivering them as machine-readable XML-based article files. To make these files human-readable, a Web-based article viewer displays the original text with the metadata colour-coded, and offers additional context-specific functionality (e.g. to view a three-dimensional structure image, to retrieve the protein sequence, to get the PDB entry, to define the ontology term) – an excerpt from a marked-up article is shown in
<xref ref-type="fig" rid="F6">Figure 6</xref>
. Statistics relating to GO-term usage across all the articles are also generated and these terms can be used for searching or retrieving similar articles.</p>

<p>The novelty of BioLit is in providing a searchable Web-based database of a filtered subset of automatically marked-up PMC articles, obviating the need for users to search multiple databases for information pertinent to specific queries. The mark-up it provides is not semantic, in the sense of inferring relationships between terms and identifiers, but does provide valuable anchors for text-mining algorithms, which are likely to be of value to database curators. To generalize its functionality, the aim is to make the system applicable to all open-access literature and to expand the range of biological databases and ontologies it uses. To make the data more machine-accessible, it is also planned to provide Web services to fetch articles or metadata.</p>
<p>With these first steps, Fink et al. [
<xref ref-type="bibr" rid="B55">55</xref>
] are working towards a vision in which literature becomes just another interface to data in databases, and vice versa. How close they will come to realizing this vision will depend not only on the continued success of open-access initiatives, but also on the success of community efforts to standardize mark-up of semantic content, and especially on the percolation of these ideas into routine scientific writing and publishing practices.</p>

<p>In another interesting adventure in semantic publishing, Shotton et al. [
<xref ref-type="bibr" rid="B34">34</xref>
] chose an article in
<italic>PLoS NTD</italic>
as a target for enrichment. The criteria for selecting this particular article included the fact that it contained various different data types (geospatial data, disease-incidence data, serological-assay results, and so on) presented in a variety of formats (maps, bar charts, scatter plots, etc.); moreover, it was available in an XML format, published under a Creative Commons License – the article could therefore be modified and re-published.</p>
<p>The semantic enhancements added to the article include: live Digital Object Identifiers (DOIs) and hyperlinks; mark-up of textual terms (disease, habitat, organism, protein, taxon, etc.), with links to external information resources (see
<xref ref-type="fig" rid="F7">Figure 7</xref>
); interactive figures; a re-orderable reference list; a document summary, with a study summary, tag cloud and citation analysis; mouse-over boxes for displaying the key supporting statements from a cited reference; and tag trees for bringing together semantically related terms. Augmenting these enhancements are both downloadable spreadsheets containing data from the tables and figures, enriched with provenance information, and examples of ‘mashups’ with data from other articles and Google Maps. In addition, a ‘citation typing’ ontology was implemented to allow compilation of machine-readable metadata relating both to the article and to its cited references [

<p>The enhancements described in this study are platform- and browser-dependent and are confined to a single article. However, in the hope of stimulating more general take-up of their ideas, the authors assert that what they achieved was not “rocket science”, but was accomplished using standard mark-up languages, ontologies, style sheets, programmatic interfaces, and so on. They recognize, nevertheless, that their exemplar was manually intensive, and that to bring the approaches they espouse into mainstream publishing protocols will require greater degrees of automation.</p>

<title>Elsevier Grand Challenge</title>
<p>In 2008, to stimulate further efforts to improve the way scientific information is communicated and used, Elsevier announced its Grand Challenge of Knowledge Enhancement in the Life Sciences. The focus of the contest was to develop tools for semantic annotation of journals and text-based databases, to improve access to, and sharing of, the knowledge contained within them: in short, to change the way that science is published.</p>
<p>The winners of the contest developed a tool (Reflect) that addresses the routine need of life scientists to be able both to jump from gene or protein names to their molecular sequences, and to understand more about particular genes, proteins or small molecules encountered in the literature [
<xref ref-type="bibr" rid="B44">44</xref>
]. With a single mouse click, Reflect tags such entities when they occur in webpages; it does this by drawing on a large, consolidated dictionary (containing 4.3 million small molecules and >1.5 million proteins from 373 organisms) that links names and synonyms to source databases. When clicked on, the tagged items invoke pop-ups (see
<xref ref-type="fig" rid="F8">Figure 8</xref>
) displaying brief summaries of key features (domain structures, small-molecule structures, interaction partners, etc.), and allow navigation to core biological databases like UniProtKB.</p>

<p>Reflect was optimized for speed rather than accuracy – inevitably, therefore, there are errors in the tagging. As part of their ongoing system developments, the authors plan to address this problem by implementing mechanisms for community-based, collaborative editing of some of the information provided by Reflect, and especially to allow correction of some of its errors. The system is currently accessible to users directly via the Web, and as Firefox or Internet Explorer plug-ins; in future, programmatic access via Web services might also be possible, obviating the need for users to install browser plug-ins.</p>

<title>Liquid Publications</title>
<p>A rather different slant on the problem of dissemination and re-use of scientific knowledge is offered by the Liquid Publication Project, a European initiative partnered by Springer Verlag [
<xref ref-type="bibr" rid="B60">60</xref>
]. The intention here is for publications to become fluid entities, created in a collaborative and evolutionary fashion over time, in much the same way as open-source software is developed; there are also parallels here with successful social/collaborative annotation models such as Wikipedia.</p>
<p>This project aims to exploit emerging Web technologies to spur a transition away from traditional ‘solid’ scientific papers (which crystallize fragments of scientific knowledge at a point in time) to Liquid Publications, which may adopt multiple shapes, evolve continuously and are enriched by multiple sources. The idea is to promote early circulation of innovative ideas, to optimize the processes by which researchers create, assess and disseminate knowledge, and to stimulate publishers to offer more advanced services (including the maintenance of scientific social networks, automatic notification of new contributions in certain areas, social bookmarking, collaborative authoring, blogging and reviewing) – to become “the yahoo, flickr, digg and delicious of the publication world” [
<xref ref-type="bibr" rid="B60">60</xref>
].</p>
<p>It is hard to assess how far the project has progressed towards achieving these goals. By definition, there is no current solid publication summarizing the work; and the Liquid Document available on the project website (version 2.3), itself an evolution of a previous paper (which argues “why the current publication and review model is killing research and wasting your money” [
<xref ref-type="bibr" rid="B61">61</xref>
]), was last updated in 2007. Like water, therefore, the impact of Liquid Publications is difficult to grasp.</p>

<title>Are we there yet?</title>
<p>Although the initiatives outlined above may differ slightly in their specific aims, they are nevertheless reflections of the same overall aspiration – to make the data and knowledge sequestered in the literature more readily accessible and re-usable. The results, to date, are encouraging, and it is interesting to see the common themes that have emerged: most are HTML- or XML-based, providing hyperlinks to external websites and term definitions from relevant ontologies via colour-coded textual highlights. But these are only first steps towards much more far-reaching possibilities, and new ideas and new tools are clearly still needed. Lynch, for example, imagines a future in which there exists a wide range of specialized visualization tools for various forms of structured data [
<xref ref-type="bibr" rid="B37">37</xref>
]. It would be useful, he suggests, to be able to toggle between a rendered image and its underlying data-set, or between a published table of numerical values and their graphical representation, perhaps like the scenario shown in

<p>In a similar state of reverie, Bourne has a vision in which journals provide software for visualizing and interpreting their published content, obviating the need for specialized knowledge in handling esoteric tools; he envisages such software ultimately allowing various forms of basic analysis (simple statistical tests, principal-component analysis, and so on), making new levels of comprehension possible [

<xref ref-type="bibr" rid="B63">63</xref>

<p>These concrete initiatives and wistful imaginings bear witness to the yearning within the community for more productive ways of interacting with the literature. In 2005, Bourne asked, “Is the technology available to support the next steps and is the scientific community ready for such a change?” [
<xref ref-type="bibr" rid="B36">36</xref>
]. An important step forward would be to assign standard identifiers, not only to papers, as we do now, but also to their authors [
<xref ref-type="bibr" rid="B65">65</xref>
] and to the biological objects the papers describe. An outcome of such an approach would be the ability to find all papers that reference, say, a particular sequence motif [
<xref ref-type="bibr" rid="B36">36</xref>
]. Dreaming that, from a paper, researchers could one day retrieve and manipulate the associated data, and possibly discover new links and relationships using such tools, he asks, “What if the data in an online paper were to become more alive?” (see

<p>Many of the necessary tools (article repositories, relevant ontologies, machine-readable document standards, etc.) already exist for marking up and integrating published content with data in public databases. Fink and Bourne argue that one of the reasons why publications have benefited so little from the opportunities offered by such infrastructure is probably cultural [
<xref ref-type="bibr" rid="B38">38</xref>
]: simply, the community has grown up with static manuscripts, and most electronic articles are still delivered in unexpressive, semantically limited forms, like PDF or HTML [
<xref ref-type="bibr" rid="B37">37</xref>
], which some authors accuse of impeding the progress of scholarship.</p>
<p>To gain the most from electronic articles, and especially from dormant document archives, semantic mark-up of content is clearly necessary. But retrospective addition of semantics to legacy data is complex, labour-intensive and costly. A balance must therefore be found between the degree of automation it is possible to introduce to the process, and the degree of cultural change it is reasonable to expect in a research community that has not hitherto considered the relationship between data and published articles, and has hence not been concerned about providing the semantic context necessary to unite them. In the long-run, it is to be hoped that the benefits of semantic mark-up, and the availability of the right tools, will together help to seed this much-needed cultural change: compare and contrast, for example, the pages shown in

<p>What is clear is that new technologies will emerge (and indeed, are already emerging) to promote a fundamental shift away from how scholarly communication currently works [
<xref ref-type="bibr" rid="B69">69</xref>
]. A key driver of this change will be realization of the benefits that accrue from having more explicit links between articles and the data and concepts they describe [
<xref ref-type="bibr" rid="B70">70</xref>
]. Processes that will particularly profit from such links are peer review and the dissemination of (reliable) knowledge. Were a paper to become an interactive interface to its underlying data, it could, for example, facilitate further research across multiple articles and databases, and lead more easily to the discovery of errors; combined with suitable social technologies for community commentary, a published paper could at the same time act as its own self-correcting record. This would be an especially powerful development, as the extent to which peer review of an article extends to its underlying data is generally not at all clear, and current mechanisms for data correction, updating and maintenance are not synchronized with those for managing the literature [
<xref ref-type="bibr" rid="B37">37</xref>
]. Thus, as Antezana points out, reported ‘facts’ may be incomplete, incorrect or simply false, and new knowledge may refute ‘accepted’ information [
<xref ref-type="bibr" rid="B10">10</xref>
]. Unfortunately, however, we have no way of knowing what the error rates in the literature or in biological databases actually are, or indeed what are the rates of propagation of those errors between databases and papers, and vice versa. The ramifications of new tools and technologies that could support the discovery of errors and inconsistencies, which could allow us to track and to consistently record the evolution of the current state of our knowledge, are therefore potentially profound. Consider, for a moment, the example illustrated in

<p>In 2007, Liu et al. [
<xref ref-type="bibr" rid="B71">71</xref>
] reported in
<italic>Science</italic>
the discovery of a novel plant G protein-coupled receptor (GPCR), so-called GCR2 (
<bold>a</bold>
). Much of the supporting evidence rested on a ‘characteristic’ hydropathy profile (reported as a Supplementary Figure), which showed seven peaks, apparently consistent with known GPCR transmembrane (TM) domain topology (
<bold>b</bold>
). Illingworth et al. challenged this result, pointing to the clear similarity of GCR2 with LanC-like proteins and showing that the topology of the hydropathy profile was the result of the seven-fold symmetry of the inner helical toroid (the blue/green region in the centre of the structure) of this globular protein (
<bold>c</bold>
) [
<xref ref-type="bibr" rid="B66">66</xref>
]. It is interesting to compare a hydropathy plot (
<bold>d</bold>
) with that reported by Liu et al. (
<bold>b</bold>
), generated using the same DAS TM prediction server [
<xref ref-type="bibr" rid="B72">72</xref>
] – note the omission of the significance bars in the latter, which in the former show that only one of the seven peaks scores above the significance threshold for TM domains and hence argues strongly against this being a membrane protein. Compare the structure of a
<italic>bona fide</italic>
GPCR [bovine rhodopsin, PDB code 1F88 (
<bold>e</bold>
)] with the nisin cyclase structure shown in Illingworth's paper [PDB code 2G0D (
<bold>c</bold>
)]. Despite the obvious lack of sequence and structural similarity of GCR2 to genuine GPCRs, and its clear affiliation with the LanC-like proteins, this error has been propagated to the description line of its UniProt entry, even though the entry contains database cross-references to LanC-like proteins rather than GPCRs (

). For readers viewing this article using UD, click on the UD logos in the Figure to explore this scenario further.

<p>Sharing knowledge is at the philosophical root of scientific scholarship, and our publishing systems were designed to help us do this. But Wilbanks asserts that, in the aftermath of the “earthquake of modern information and communication technologies”, we are not sharing information efficiently: we need infrastructures that facilitate knowledge sharing and integration, rather than mere Web publishing [
<xref ref-type="bibr" rid="B11">11</xref>
]. He bemoans the lack of standardized mechanisms to connect knowledge, which means that, “we can't begin to integrate articles with databases” not least because “the actors in the articles (the genes, proteins, cells and diseases) are described in hundreds of databases.” Solving this will not be easy; much of it, he warns, will be “very, very hard. But the current system is simply not working” [
<xref ref-type="bibr" rid="B11">11</xref>
].</p>
<p>While there is a sobering degree of truth in these comments, we believe that growing awareness of the issues, coupled with a community-wide desire for progress, has stimulated some promising developments. Let's take a closer look, in the next section, at a new initiative from Portland Press Limited.</p>

<title>The Semantic
<italic>Biochemical Journal</italic>
experiment</title>
<p>The Semantic
<italic>Biochemical Journal</italic>
(
<italic>BJ</italic>
) experiment was a collaborative project involving the
<italic>BJ</italic>
editorial staff and the developers of Utopia [
<xref ref-type="bibr" rid="B73">73</xref>
], a software suite that semantically integrates visualization and data-analysis tools with document-reading and document-management utilities. The principal aim of the project was to make the content of
<italic>BJ</italic>
electronic publications and supplementary data richer and more accessible. To achieve this, Utopia was integrated with in-house editorial and document-management workflows, allowing copy editors to mark up content prior to publication; this removed the mark-up burden from submitting authors, and ensured rigour and consistency from the outset.</p>
<p>The UD reader works by creating unique fingerprints of document contents as they are rendered onscreen, identifying key typographical and bibliometric features (authors, figures, references and so on). But the real innovation lies in being able to turn static images, tables and text into objects that can be linked, annotated, visualized and analysed interactively. The additional data are overlaid rather than embedded in the documents, leaving their provenance and integrity intact; this means that features can be reliably associated with any version of a file, even one that has lain unread on a laptop for many years. In this way, the electronic document is transformed from a digital facsimile of its printed counterpart into a gateway to related knowledge, providing the research community with focused interactive access to analysis tools, external resources and the literature.</p>
<p>For the purposes of this experiment, all the papers in the current issue of the
<italic>BJ</italic>
have been marked-up by the Journal's copy editors (as will subsequent issues). For practical reasons, features relating to protein sequence and structure analysis have been the main targets, because this was the functionality built into the original Utopia toolkit [
<xref ref-type="bibr" rid="B74">74</xref>
]. At the time of writing, the additional mark-up provides: links from the text to external websites (including major databases such as UniProtKB [
<xref ref-type="bibr" rid="B17">17</xref>
], PDB [
<xref ref-type="bibr" rid="B56">56</xref>
] and InterPro [
<xref ref-type="bibr" rid="B75">75</xref>
]); term definitions from ontologies and controlled vocabularies; extra embedded data and materials (including images, videos and so on); and links to interactive tools for sequence alignment and three-dimensional molecular visualization. Utopia does not itself provide any domain-specific functionality for processing or analysing data, but relies on external services; these are accessed via plug-ins whose appearance in the software interface is mediated by a ‘semantic core’ (the core can be customized to any subject area by incorporating the relevant discipline-specific ontologies).</p>
<p>Reliance on external Web services is a strength of the system, in the sense that it allows greater flexibility for customizing the functionality of the software (obviating the need for the developers to second-guess all current and future potential user needs); it may also be a weakness, however, because when those external services become unavailable (e.g. owing to routine maintenance or faulty operation of some kind), their functionality also becomes unavailable to Utopia. Such issues (which afflict all systems that rely on Web services, not just Utopia) are mitigated to some extent by the establishment of a Web-service registry, which systematically monitors and provides feedback on the status of its registered services [
<xref ref-type="bibr" rid="B76">76</xref>
].</p>
<p>As with other projects outlined in the present review, UD is still at an early stage of development and there is much more work to be done. As the system is readily customizable, we plan to extend its scope, for example, to systems and chemical biology, and to the medical and health sciences, as many of the requisite chemical, systems biology, biomedical, disease and anatomy ontologies are already in place and accessible via the OBO Foundry.</p>
<p>Another challenge concerns a feature of UD that allows readers to append notes or comments to articles, and how this is developed in future. There are at least three different scenarios to consider here: (i) a reader might wish to make a ‘note to self’ in the margin, for future reference; (ii) a reviewer might wish to make several marginal notes, possibly to be shared with other reviewers and journal editorial staff; and (iii) a reader might wish to append notes to be shared with all subsequent readers of the article (e.g. because the paper represents an exciting breakthrough or because it contains an error) without having to establish a personal blog or to write a formal Letter to the Editor. These scenarios involve different security issues, and work will be needed to investigate and establish appropriate ‘webs of trust’.</p>
<p>For now, to gain further insights into the status of the Semantic
<italic>Biochemical Journal</italic>
experiment, we encourage readers to view the PDFs of other articles in this
<italic>BJ</italic>
issue (and subsequent issues) through the animating lens of UD.</p>

<title>DISCUSSION</title>
<sec>
<title>The PDF debate</title>
<p>In recent years, the literature has seen the value of PDF as a mechanism for digitizing the printed page rather hotly contested. PDF, although easy for humans to read, is not regarded as an efficient medium for gathering information, nor for sharing, integrating and interacting with knowledge; it is considered semantically limited by comparison with XML, and antithetical to the spirit of the Web [
<xref ref-type="bibr" rid="B11">11</xref>
,
<xref ref-type="bibr" rid="B34">34</xref>
,
<xref ref-type="bibr" rid="B35">35</xref>
,
<xref ref-type="bibr" rid="B37">37</xref>
,
<xref ref-type="bibr" rid="B77">77</xref>
].</p>
<p>Notwithstanding the critics, PDFs are still the dominant means of dissemination of scientific papers. For the human reader, they are like ‘electronic paper’ – they generally inherit the standard typesetting conventions of the original journal and hence feel ‘natural’ to read. People also like to have their own copies of documents, which can be read offline, with the added comfort of knowing that the PDF won’t disappear even if its originating website does.</p>
<p>Adobe's PDF has therefore become the
<italic>de facto</italic>
standard for document dissemination (although technically a proprietary format, it is sufficiently open to be supported by all platforms). It supports basic annotation and hyperlinking (within a document, and to external sources), and also allows inclusion of metadata. Interestingly, earlier this year, the Charlesworth Group, working with Nature Publishing Group, completed a project to incorporate eXtensible Metadata Platform (XMP) metadata within
<italic>Nature</italic>
's online PDFs (the metadata include article titles, author details, keywords, images, DOIs and so on;
<ext-link ext-link-type="uri" xlink:href="http://www.nature.com/press_releases/charlesworth.html">http://www.nature.com/press_releases/charlesworth.html</ext-link>
). This has the dual advantage of presenting scholarly information both in a human-readable form and in a format accessible to software applications. However, although all new
<italic>Nature</italic>
research articles will contain embedded XMP metadata as they are published, there are no plans for retrospective mark-up of the
<italic>Nature</italic>
archives. Moreover, as the metadata are embedded at the point of publication, they are effectively as fixed as the original PDF and are unavailable for future modification. This is in contrast with the approach taken with UD, which vivifies the static PDF document by overlaying dynamic, customizable metadata, in turn adding evolvable, interactive content to the underlying file. As mentioned above, this system also yields the potential for sharing community comments and annotations on any document (past and present), storing them on a common server and making them accessible to future semantic Web applications.</p>
<p>Clearly, the technology to add value to PDF documents, whether with links to websites, links to interactive analysis tools or to live online commentaries or blogs, is with us now; the time is therefore ripe to exploit it. On a technical level, the ultimate goal is effective ‘knowledge management’ [
<xref ref-type="bibr" rid="B11">11</xref>
,
<xref ref-type="bibr" rid="B78">78</xref>
]; on a human level, it is to deliver to the research community a tangible way not simply to bring sanity to the sprawling mass of scientific data and literature, but to rescue the knowledge being systematically entombed in world-wide literature and data archives.</p>
</sec>
<sec>
<title>Achievements and challenges</title>
<p>The projects outlined in the previous sections bear witness to the growing momentum, fuelled by community pressure, to tackle these issues, to get more out of digital documents and especially to facilitate access to underlying research data. The projects differ a little in scale and focus; all are, in some sense, experimental. They therefore present opportunities to learn what has worked best, what hasn't worked so well, and why. They also serve as valuable models, revealing what more needs to be done and what obstacles still exist before we can realize the goal of truly integrated literature and research data.</p>
<p>The RSC have taken pioneering steps with Prospect and ChemSpider. The content mark-up they have achieved looks set to become richer and wider in scope, and will doubtless extend to more of their own published content over time. The application of BioLit to a subset of PMC articles also looks promising but, as with the
<italic>FEBS Letters</italic>
experiment, in its original implementation it links only to a single database – to be optimally useful, these initiatives would need to embrace many more biomedical tools and resources.</p>
<p>Shotton's project [
<xref ref-type="bibr" rid="B34">34</xref>
] with
<italic>PLoS NTD</italic>
was, in some ways, more ambitious in scope. Despite being limited to a single article, the semantic enhancement provided was found to be a labour-intensive exercise. To render their approach more cost-effective, Shotton recognized the need for greater levels of automation, and he pointed to tools like Reflect to help ease manual mark-up burdens. However, Reflect and similar tools that use named-entity recognition are error prone [
<xref ref-type="bibr" rid="B79">79</xref>
,
<xref ref-type="bibr" rid="B80">80</xref>
]. For now, then, a balance has to be found between the degree of automation necessary to make semantic enrichment feasible and the degree of manual intervention necessary to ensure rigour and consistency of mark-up. As a trivial illustration, look more closely at the definition Reflect gives to OMP in
<xref ref-type="fig" rid="F8">Figure 8</xref>
– Olfactory Marker Protein. Ironically, directly above the pop-up, the correct expansion of the acronym is given in the original text – Outer Membrane Protein. What is simple to spot by eye is much harder to achieve computationally. Issues of this type are the scourge of text-miners, and there are no perfect solutions. As an indication of the complexity of the problem, the Acromine acronym look-up service [
<xref ref-type="bibr" rid="B81">81</xref>
] lists 11 definitions for OMP. This is why Reflect's developers are seeking ways to engage the community in correcting the errors made by their software.</p>
<p>On the other side of the coin, if experiments in semantic publishing are to be truly successful, an appropriate balance must also be found between the degree of manual intervention required by journal copy editors, pre-publication, and the amount of additional work demanded of authors to facilitate machine-access to their results. Imposing processes on authors that take them out of their comfort zones and add to their workloads are unlikely to succeed quickly, if at all. The
<italic>FEBS Letters</italic>
experiment is a case in point: author take-up has been fairly limited, and the structured abstracts that do now exist have not been made available through Medline; it is likely that the complexity of SDAs and the extra cognitive load and time burdens on authors are hurdles too great for most to be able to negotiate successfully.</p>
</sec>
<sec>
<title>Why semantic mark-up is hard</title>
<p>Most of the projects mentioned in the present review have exploited fairly traditional text-mining methods, in conjunction with controlled vocabularies and ontologies, to provide a spring-board from marked-up entities within published texts to external webpages. As such, they come with all the limitations of current text-mining tools in terms of precision; they also bring an over-head to readers in terms of having both to identify and to correct errors – having to know that an error really is an error is perhaps one of the biggest pitfalls. Moreover, as Fink and Bourne point out for BioLit, the mark-up these approaches provide is not truly semantic, in terms of inferring relationships [
<xref ref-type="bibr" rid="B55">55</xref>
]. This is partly because most electronic articles are delivered in what are considered to be fixed, semantically limited forms (PDF and HTML) [
<xref ref-type="bibr" rid="B37">37</xref>
,
<xref ref-type="bibr" rid="B82">82</xref>
], but partly also because genuine semantic mark-up is hard – it is labour intensive; it requires significant financial investment; it demands adoption of, and adherence to, common mark-up standards; and, perhaps most difficult of all, it involves cultural change.</p>
<p>The philosophy embodied in UD is to hide from authors and readers as much of the underlying complexity as possible, to avoid requiring them to change their existing document-reading behaviours, and to present no additional barriers to publication. But, like the other work discussed in this review, UD is also an experiment. The success of the experiment will ultimately depend on several factors, including whether the barriers to adoption are sufficiently low; whether the approach is found to add sufficient value; whether the cost of the approach is sustainable; and whether entire communities can be galvanized to move forward and work together.</p>
</sec>
<sec>
<title>The cost of doing it</title>
<p>The
<italic>FEBS Letters</italic>
experiment involved a significant time investment on the part of journal editors, MINT curators and co-operating authors – the harder authors found it to engage with the mark-up process, the greater the burdens that fell to curators. The RSC's experience with project Prospect was also labour intensive, involving collaboration with text-miners and the input of skilled, in-house domain-specialists, with sufficient breadth of expertize to understand XML, to edit, mine, mark-up and ‘user-friendlify’ the final results. Shotton estimates that his own experiment with one
<italic>PLoS NTD</italic>
article required ten person-weeks of effort (although, with the learning phase behind them, the exercise could doubtless be repeated more swiftly) [
<xref ref-type="bibr" rid="B34">34</xref>
]. Similarly, the Semantic
<italic>Biochemical Journal</italic>
experiment involved close collaboration with
<italic>BJ</italic>
editorial staff, and more than 2 person-years of technical effort to build the necessary infrastructure to make future mark-up relatively trivial. Overall then, these experiments have not been cheap.</p>
</sec>
<sec>
<title>The price of not doing it</title>
<p>If the cost of semantic publishing seems high, then we also need to ask, what is the price of not doing it? From the results of the experiments we have seen to date, there is clearly a need to move forward and still a great deal of scope to innovate. If we fail to move forward in a collaborative way, if we fail to engage the key players, the price will be high. We will continue to bury scientific knowledge, as we routinely do now, in static, unconnected journal articles; to sequester fragments of that knowledge in disparate databases that are largely inaccessible from journal pages; to further waste countless hours of scientists' time either repeating experiments they didn't know had been performed before, or worse, trying to verify facts they didn't know had been shown to be false. In short, we will continue to fail to get the most from our literature, we will continue to fail to know what we know, and will continue to do science a considerable disservice.</p>
</sec>
<sec>
<title>What we've learned</title>
<p>It is clear from these experiments that the way ahead must involve genuine collaboration between life scientists, computer scientists, bio- and chemo-informaticians, database curators, publishers, learned societies, librarians and many others – the necessary advances in current publishing practices cannot be achieved in isolation. Although necessary proofs of principle, the problems will not be solved by linking a single database to a single article, by linking a single database to several articles, or by linking several databases to a single issue of a single journal; nor will they be solved by developing and protecting proprietary mark-up tools and ontologies. The real challenge concerns the need for interactions between all databases, all journals, and all research data, and will involve the commitment of entire communities.</p>
<p>The pace of progress will ultimately be determined by the extent to which the research and publishing communities can be persuaded to work together to promote new data standards and to build new, open ontologies; it will also depend on the extent to which publishers are prepared to engage with technology providers to evolve their traditional roles in scholarly communication towards knowledge-management solutions, and in turn, on the extent to which authors are prepared to evolve their habits in line with the ongoing publishing revolution.</p>
</sec>
<sec>
<title>A call to arms</title>
<p>Learned societies, publishers and their editorial boards are well placed to champion the standards for manuscript mark-up necessary to drive effective knowledge dissemination in future, and to garner community support for those standards. To this end, the support of the International Association of Scientific, Technical and Medical Publishers and of societies such as the Biochemical Society, the International Society for Computational Biology and the newly-formed International Society for Biocuration would substantially help in taking the next steps forward, as would dia logues with the publishers and curators whose journals and databases have been the focus of the experiments outlined in the present review. There are likely to be many other stakeholders, with vested interests in their own domains of knowledge. It will therefore be essential to stimulate constructive discussions and collaborations among all the relevant players. The seeds of these much-needed debates could be sown, perhaps, on the various society and community discussion boards, on prominent blogs (e.g.
<ext-link ext-link-type="uri" xlink:href="http://blogs.bbsrc.ac.uk/">http://blogs.bbsrc.ac.uk/</ext-link>
), and on journal commentary pages, or placed on the agenda at International meetings. As Seringhaus and Gerstein point out [
<xref ref-type="bibr" rid="B21">21</xref>
], it's important not to rush at this, but to consider the issues carefully. The benefit of getting it right could be a cost-efficient investment in a new type of knowledge landscape, one that better serves the needs of new millennium readers, authors and publishers – it's a potential win, win, win situation, if we build on the foundations together.</p>
