Metadata is the data that describes, locates and manages a specific resource object, whose discovering and obtaining is meanwhile facilitated. The application and popularization of metadata standard is propitious to the normalized description and sharing of resources. There are various metadata standards because of the diversity of resources and different demands of application, which hinders the share of resources. The present study first makes a brief introduction of some usual ways of metadata interoperation, such as metadata crosswalk, metadata open searching, semantic metadata interoperation etc., then presents a tentative research on metadata registry (MR) and automatic metadata extraction.
