    Groupware is explicitly designed to support the cooperation among group members. The implementation of cooperation-aware groupware is supported by several object-oriented toolkits and frameworks, but there is no unified way to model applications built on top of these. We have proposed UML-G as an extensible UML profile for modeling groupware and are in the process of turning it into a community effort. In this article, we identify modeling needs specific to shared data modeling. Shared data is a prerequisite to supporting cooperating users. We present UML extensions to address the identified needs as a part of UML-G. Usage scenarios demonstrate how UML-G can be used to assist shared data modeling. UML-G provides explicit modeling of shared data related aspects. In addition, it supports a shared understanding between developers, which is independent of, and thus abstracts from, the latter implementation. CASE tool support for UML-G strengthens its practical relevance.

    The WWW makes learning materials widely accessible and provides an environment where people can learn across time and space. However, the simple read-only information structure on the Web provides little or very limited guidance to learners, especially when they want to learn how to do something through interaction with computers and other people. We suggest overcoming the problem by introducing a graphical hypermedia-based process representation and a cooperative process enactment support. The hypermedia-based process structure is accessible on the WWW. It contains a rich set of associated materials with which people can seamlessly interact while they are systematically carrying out the process they are learning under the guidance of computers or tutors. A hypermedia-based process support system and two use cases are presented. The use cases show that such a system can not only provide traditional learning support, but also offers novel cooperative hypermedia based support for the learning of process knowledge.
