WSMO Choreography and Orchestration Meeting

22nd and 23rd September 2005, Innsbruck, Austria

Agenda and Schedule
Further Material


Semantic Web Services (SWS), Combining Web Services and Semantic Web, opens up new horizon to support the automation business processes. Having machine understandable description of Web Services, SWS can have significant impact in the areas of business process integration as it can support interoperation between independently developed business applications.

In January 2004, a new Euopean initiative has started which attracted a lot of attention in the area of Semantic Desription of Web Services: The Web Service Modelling Ontology (WSMO). WSMO is an ontology which defines the basic elements of a Semantic Description of Web Services and aims at facilitating and simplifying the integration of applications and businesses to solve the integration problem. The joint working groups around this initative are developing a proper formal description language for Semantic Web Service (WSML) based on the WSMO conceptual model and the development of a reference implementation of the WSMO model (WSMX).

We are organizing a Workshop on Choreography and Orchestration in WSMO in Innsbruck, Austria from September 22 - 23, 2005. The workshop aims at the presentation and discussion of current state of the choreography and orchestration models in WSMO, of open issues around this model and the evolution of these models.
