Modeling and implementation of unified semantic Web platform

More and more infrastructure software for semantic web has emerged with the popularity of Semantic Web. Now Semantic Web applications are calling for different infrastructure software to support essential ontology operations, such as ontology persistence, ontology consistency, ontology query, ontology inanagenient, reasoning and so on. This paper brings forward the vision about integration of ontology operations based on the unified semantic web software plaform. It introduces a model in which varied operations of ontology are added, updated and deleted dynamically. Furthermore, a USWP ("Unified Semantic Web Platform") is implemented according to this model. As an ontology platform using the standard of RDF[1] and RQL([13]), the key characteristic of the USWP is that the platform has a "total solution " for the semantic web applications built on an expansible, flexible, scalable and open architecture. Third part's ontology operation modules can be deployed into USWP with a wrapper under the standard of OOU ("Ontology Operation Unit") and can share data flow with other modules using DOOD ("Dynamical Operation Ontology Domain") dynamically.
