From WS-CDL to OWL： Mapping Choreography to ITs Corresponding Ontology

Web Service Choreography Description Language （WS-CDL） Known as service-oriented architecture （SOA） standard describes the inter-organizational collaborations. The language describes collaborations between participants in the form of messages exchanged from a global perspective and in pair-to-pair pattern. Fundamental need to create distributed collaborations is providing the same viewpoints on concepts that used in the messages exchanged between different participants. Semantic Web and ontology tools are used for resolving this requirement. Ontology includes definitions of all concepts and attributes, communications and conclusion rules governing the concepts and attributes. This paper provides a method for mapping WS-CDL to the corresponding Ontology and Web Ontology Language （OWL） file. This method by attention to semantic issues could used to simplification and automation systems design based on service-oriented architecture, and also helps to making executive WS-CDL standard.
