Working Group Report On Coordination Architectures For Distributed Web Applications

The WETICE Workshop on Coordination Architectures for Distributed Web Applications followed up to two WETICE workshops in 1996 and 1997 that dealt with coordination issues in the context of Web-agents ([2] [1]). It brought together nearly twenty professionals; of these, about one third had industrial affiliations, whereas most originated from academia. The workshop program consisted of technical presentations plus discussions, for which about equal time was allocated. The workshop organizers, Paolo Ciancarini and Robert Tolksdorf, received 24 submissions of papers in response to the call for papers. 11 of those were selected for publications in this proceedings. The following researchers reviewed the papers as a program committee: Farhad Arbab (CWI), Valerie Issarny (IRISA/INRIA), Edwin de Jong (Signaal), Matthias Klusch (CMU), Kurt Rothermel (Universitat Stuttgart), Paul Tarau (Universite de Moncton), Christian F. Tschudin (ICSI), and Alan Wood (University of York). The workshop organizers are indebted to their professional expertise which helped to make the workshop a success. The topics of the workshop were grouped around the Web. As the dominating platform for distributed collaborative applications, it has evolved from a static hypermedia system into a collection of services provided at different levels. Support infrastructures have to be provided in order to realize applications from these services. New ideas for collaborative applications on the Web have to be explored and tested. Of central interest within infrastructures are coordination mechanisms used in realizing distributedand concurrent services. In addition, infrastructure services have to address
