Versions for Context Dependent Information Services

摘要

Context dependent information delivery is an important requirement of cooperative information systems supporting global and mobile access. These systems must be able to adapt the content, structure and presentation of information according to various factors such as the user, the access device and the task at hand. We present a versioning model designed to manage context-varying versions of content, structure and presentation database objects. Further, we describe how this has been integrated into a general web publishing platform to dynamically compose web documents according to the current context state.
