Abstract
Abstract: With many types of scientific data, the amount of descriptive and qualifying information associated with the data values is quite variable and potentially large compared with the number of actual data values. This problem has been found to be particularly acute when dealing with data about the nutrient composition of foods, and a system—based on textual markup rather than, for example, the relational model—has been developed to deal with it. This paper discusses the types of metadata encountered and the problems associated with dealing with them, and then describes this alternative approach. The approach described has been installed in several locations around the world, and is in preliminary use as a tool for interchanging data among different databases as well as local database management.
