EXPRESS: EXPressing REstful Semantic Web Services

Abstract

Existing approaches to Semantic Web Services (SWS) require both a domain ontology and a semantic description of the service. We propose EXPRESS a lightweight approach to SWS. Its simplicity stems from the similarities between REST and the Semantic Web such as resource-realization, self?describing representations, and uniform interfaces. The semantics of a service is elicited from the resource descriptions in the domain ontology and the semantics of the uniform interface, hence eliminating the need for ontologically describing services. In this poster we describe EXPRESS and show how it represents different service types. It also discusses our ongoing and future work on service discovery and choreograph
