Lightweight Semantic Extensions for SOA

Executive Summary

Semantic Web Service (SWS) frameworks especially address service discovery, composition and execution. This article first describes WSMO-Lite, a lightweight ontology of service semantics that builds on a W3C standard for semantic annotations of WSDL. WSMO-Lite distinguishes four kinds of service semantics (functional, nonfunctional, behavioral and information) and it provides a simple and modular ontology for capturing these semantics. Secondly, the article describes MicroWSMO, an approach for semantic description of RESTful services, which have been largely neglected both in context of SOA and in SWS research. MicroWSMO uses WSMO-Lite semantics and thus integrates RESTful services in our Semantic Web Service automation.
