A project partially funded by the EU in the ESPRIT Open LTR programme
under contract number 20179. Project partners are the TU Berlin (Fachbereich 13, Informatik,
Forschungsgruppe KIT/FLP)
and the Department of Computer
Science, University of Bologna
The project PageSpace aims at supporting networked applications which require
interaction between distributed software components and active processing. It
is based on the Internet and the World Wide Web but introduces a notion of
active Web-pages that are capable of executing code.
The possibility of including code within a Web-Page will be a major direction
in the development of the Web as a standard platform for networked
applications. However, this still leaves open the question, how these active
entities coordinate their work.
In the PageSpace, the technology of coordination languages will be employed to
support this necessary coordination. Coordination languages are designed to
add this capability to active entities in order to enable them to form an
ensemble in which they work together.
The project takes a twofold approach in the first phase. Starting from an
analysis of applications' requirements, a set of necessary services will be
derived that have to be supported by the PageSpace platform. The project
focuses on the application domains groupware and workflow-modeling. Starting
from Web- and coordination-technology, a platform will be defined and its
implementation strategy be developed. At the end of the first phase, an
experimental implementation will demonstrate the potential of the platform to
support the named application domains.
The second phase of the project will develop the PageSpace platform as an
engineering product. Both system software and applications shall be developed
in conjunction with industrial partners to show the feasibility of the
PageSpace. The platform shall be implemented at a European scale.
