A Resource Description Framework for Service

With the popularity of Web services technology, the amount of the Web services resources is on the increase. It is well-known that the semantic Web technologies can bring the Web services into effect better, so the academia and enterprises give more and more attentions to the semantic Web technologies. But the semantic Web technologies have to face some difficulties below: the abilities of semantic description is inadequate so that the Web services resources do not have enough the semantic information, and it is hard to support the running of diversified system software and application software. In order to solve these problems, this article introduces a framework of semantic software, proposes a model named RDF4S (recourse description framework for service). It's describe Web service through adding semantics annotation based on ontology. Compared with other description model, the main advantage consists in its flexibility caused by RDF4S.
