Web service description, advertising and discovery: WSDL and beyond
Wilfried Lemahieu · 2001
Abstract. This paper discusses the predicaments surrounding web service description, advertising and discovery. It provides an overview of the various technologies involved and advocates how current state-of-the-art standards such as UDDI and WSDL can be enhanced by means of concepts from the semantic web vision such as RDF, RDF Schema and DAML+OIL. Moreover, it is shown how semantic metadata specifications can be considered as (a) layer(s) above syntactic metadata modeled by means of XML schemas. Finally, suggestions are made for further research towards the enhancement of current web ontology efforts, seen in the light of web service description. 1.
