Moderator: Amit Sheth, Semagix and University of Georgia Panel Introduction/Overview
Eduardo Gutentag, Sun Microsystems
Hugo Haas, W3C (Web Services Choreography: What and How?)
Frank Leymann, IBM -> Francisco Cubera, IBM (Choreography)
Steve Ross-Talbot, Enigmatec (Dancing to a Better Tune)
Web Service Choreography aims at using the power of Web services to allow corporations to create business processes that mirror today’s dynamic and ever-changing business needs. Corporations can expose their application software and resources as Web services so that other corporations can dynamically find and use them in their business processes. Creating a business process requires not only a clear definition of collaboration patterns of all its components but also a way of depicting standard B2B interactions. Software specifications for the area of choreography and collaboration are multiplying into a thick acronym soup: ebXML BPSS, BPML, WSCI, BPEL4WS, BPN, and BPQ are just a few in the mix. However, it is clear that a standard that transcends the boundaries of the domains of these specifications is required for providing a complete solution to this problem. This panel will debate (a) the path forward on technical drivers and developments that provide the developers the tools to reach the vision of true Web service coordination and collaboration, and (b) hurdles in broader adoption of proposed draft standards, by answering some of the following questions.
· Are there practical models for dynamic, reusable and scalable process compositions, and are there well defined and practical strategies for
· What are the technical completeness/correctness/executability issues with current proposals, and are they different from workflow
· Will there be a move from predefined business process/workflow coordination types of processes to more dynamic semi-automatically
composed processes any time soon?
· What specifications meet the requirements of EAI? B2B? Do any meet both? How does quality of service fit into this?
· Do any of the choreography technologies address the need for semantics in Web process creation? In other words, are any of the
choreography technologies moving towards incorporating semantics?
