DaveH's text as of Thu Sep 12 16:08:19 ET 2002 The WSA WG is committed to the creation an open common Web Services architecture where customers, developers, and IT vendors build solutions together--an architecture that takes the principles of interoperability, vendor-independence, and openness into account. It has become clear that a critical next step in the evolution of Web services will be the ability to compose and describe the relationships between Web services to support stateful, long-running interactions. Although differing terminology is used in the industry, such as orchestration, collaboration, coordination, conversations, etc., the terms all share a common characteristic of describing linkages and usage patterns between web services. For this purpose, and without prejudice, we use the term choreography. The WSA WG encourages the formation of an open, industry-wide working group with the aim of developing interoperable and open Web services standard(s) that support stateful, long-running interactions.
