Semantic and Syntactic modeling of component-based services for context-aware pervasive systems using OWL-S

In this paper, we present a service design methodology and specification as a basis for a pervasive context-aware service infrastructure. The service specification is based on the OWL-s specification, a standard proposed to add a semantic layer on top of WSDL web service descriptions. We have defined a set of OWL-s concepts that make it possible to express various pervasive service related properties, including service adaptation, relocation, personalization, deployment and runtime requirements. Though not straightforward to parse within strict resource boundaries, OWL-s provides an open, flexible specification language for expressing syntactic and semantic pervasive service characteristics and it increases service interoperability.
