Due to the growth in ubiquitous computing technology in the past few years, the need for context-aware service discovery across wide area networks is becoming prevalent. Current service discovery protocols lack in the ability to scale to large networks as well as semantically describe services. Thus, we propose GloServ, which is a global service discovery architecture that locates services throughout wide and local area networks. Intelligent agents within GloServ use the OWL Web Ontology Language to provide detailed service descriptions, and provide users with automatic registration and querying. This paper discusses a revision of GloServ that uses the OWL Web Ontology Language, as its ontology for describing services instead of the Resource Description Framework Schema (RDFS). We will describe how OWL is used for automated registration and querying of services throughout a global network. |
