    Cooperative work on shared information requires different kind of computing system support to coordinate the work of multiple users, to establish mutual awareness and to ensure consistency. These issues are currently tackled separately in various loosely related areas, like workflow systems, groupware, and advanced transactional models. We present a transactional model that provides a core functionality for information sharing in cooperative systems, that explicitely supports cooperation primitives and at the same time ensures consistency of results. The model has been derived from a thorough analysis of various cooperative appliciation scenarios. It is currently being implemented as an extension of an object-oriented database management system and evaluated for a cooperative document authoring application.

    Structured document storage and refined declarative and navigational access mechanisms in HyperStorM

    The combination of SGML and database technology allows to refine both declarative and navigational access mechanisms for structured document collection: with regard to declarative access, the user can formulate complex information needs without knowing a query language, the respective document type definition (DTD) or the underlying modelling. Navigational access is eased by hyperlink-rendition mechanisms going beyond plain link-integrity checking. With our approach, the database-internal representation of documents is configurable. It allows for an efficient implementation of operations, because DTD knowledge is not needed for document structure recognition. We show how the number of method invocations and the cost of parsing can be significantly reduced.
