Groupware applications have to support coordination of real persons, who are typically networked. The Internet and World Wide Web are clearly becoming the major platform for geographically distributed groupware applications. However, the Web technology in its current state does not provide enough of the necessary support services and offers no conceptual framework for them.
Currently there are plenty of opportunities for new services to be provided on the network [1]. In fact the whole world of middleware is rapidly evolving [9]. By Middleware we designate those areas of software services which ``sit'' above the traditional network protocols, and provide means for extending the commonly available services to compose and coordinate new and old programs in complex software ensembles which offer innovative services. Coordination technology can be used to integrate services for the support of applications based on federated databases, geographically distributed information spaces (such as the World Wide Web itself), and personal communication tools (eg. e-mail, news and even telephone and video devices).
The PageSpace is an abstraction which enhances the capabilities of current WWW middleware using the technology of coordination languages. The PageSpace is intended to support the design and implementation on the Web of open multiuser (groupware) software systems.
