A method and apparatus for introducing domain-specific data types with associated semantics in an RDF database system using an extensibility framework mechanism. The extensibility framework mechanism allows users to map serialized instance data for a particular user-defined data type to properties of a base data structure associated with the domain-specific data and to map instance data in base data structures to the data's serialized form. The RDF database system may return inferred properties of RDF data stored in domain-specific data types in response to a query on the data. Further, the RDF database system may infer relationships between resources in stored data.
