Role and application of pluggable business service handlers in Web services choreographies

This paper explores the challenges of constructing an architecture for e-business (B2B) interactions based on choreographies and service oriented architecture (SOA), Web services in particular. One of the WS-* specifications, which attempts to address business process integration issues is Web services choreography definition language (WS-CDL). In this paper, we present an approach to harmonization of the "global" or neutral definition of business collaborations, which WS-CDL is used for, with partner-specific implementations, which can differ in terms of platform, environment, implementation technology, etc. By introducing the concept of pluggable business service handlers we draw on work carried out by ebXML initiative, business services interfaces, in particular. We also take into account WSMO choreography effort. We analyze a possibility to use flexible business service handlers, which would smoothen the transition between public and private business processes by using flexible mapping techniques
