Abstract

An activity space is an information space with a task-specific information structure and task-specific operations defined on the structure. The purpose of an activity space is to support people to perform their tasks in a structured way. As tasks can be decomposed into more concrete tasks which are often dependent on one another, activity spaces need also to be decomposable into subactivity spaces that may be dependent on one another in various ways. This paper from a logical point of view explores strategies for decomposing and connecting activity spaces in meaningful ways. To support the logical view, a technical framework for connecting activity space is outlined, which consists of four methodologies: linking, transformation, integration and sharing. Examples are given to demonstrate how activity spaces are connected through each of the methodologies or a combination of these methodologies.

Key words

hypertext, hypermedia, activity space, framework, schema integration.
