Abstract The paper studies on the key technology for realizing the semantic expansion of institutional repository based on linked data. Taking the CASIR for example, the authors extract the entity relationship of the CASIR and add some constraint rules to it, use the D2R to carry out the knowledge representation and semantic annotation as RDF format. Finally, it can expand the CASIR to DC、FOAF、ISWC、VCARD, and so on. In fact, the method lays a good foundation in making CASIR provide not only the basic service but also a real semantic integration service with its rationality and feasibility in the future.
