Abstract

The explosive popularity of mashups has given rise to a plethora of web-based tools for rapidly building mashups with minimal programming effort. In turn, this has spurred interest in using these tools to empower end-users to build situational applications for business. Situational applications based on Reo (SABRE) is a service composition platform that addresses service heterogeneity as a first-class concern by adopting a mashup’s data-centric approach. Built atop the Reo coordination language, SABRE provides tools to combine, filter and transform web services and data sources like RSS and ATOM feeds. Whereas other mashup platforms intermingle data transformation logic and I/O concerns, we aim to clearly separate them by formalising coordination logic within a mashup. Reo’s well-defined compositional semantics opens up the possibility of constructing a mashup’s core logic from a library of prebuilt connectors. Input/output in SABRE is handled by service stubs generated by combining a syntactic service specification such as WSDL with a constraint automaton specifying service behaviour. These stubs insulate services from misbehaving clients while protecting clients against services that do not conform to their contracts. We believe these are compelling features as mashups graduate from curiosities on the Web to situational applications for the enterprise.
