Research On Description And Manage Model Of Component On Ontology And Metadata

Nowadays, with the development of computer hardware form single isolated ones to exoteric Internet platforms, software system is different from what it was. Software is not only information provider but also service provider.So Service-oriented architecture (SOA) was born. Service-oriented architecture is the future tread of enterprise automation realization, In SOA standard, service is constructed by component and provided in form of component or combination of component. Therefore, Service-oriented architecture corporation application emphasizes the way to satisfy changeful operation requirement of corporation as quickly as possible by software development based on component.Description method of component is base of component library and component searches. Existing description method of component attaches importance to description of static character instead of semantic information of component, especially semantic information between components and special requirement of Service-oriented component, which lead to low complete rate and corrective rate and under-satisfaction of SOA.Ontology model was adopted to put forward description method based on ontology and metadata on basis of standard of JB system and OWL-S through metadata information. This new semantic description method of service component supports Service Oriented Semantic Search, and complete rate and corrective rate of service search are also enhanced, which establishes the basis for realizing development of SOA Web component based on semantic service, on which component manage model was put forward and ontology-based semantic search technic was initially discussed.
