Publishing of Interoperable Services and Processes in UDDI

This paper presents a requirements analysis and a solution approach to representing collaborative business processes conforming to the Wf-XML/ASAP standard proposal in a UDDI registry. Wf-XML/ASAP is introduced as a coordination protocol for business collaborations focusing on loosely coupled subprocesses which involve executable and human activities. The UDDI standard as part of the web services protocol stack is designed to hold service relevant information from overall business entities down to technical fingerprints of mostly simple web services. We present a solution approach that allows to use UDDI for registering and discovering services using Wf-XML/ASAP interfaces. We conclude that while such a representation is possible, some of UDDI's structures and relationships need to be extended in order to get an appropriate service registry for interoperable services collaborative infrastructures.
