Abstract: This paper presents a metadata interoperability issues causes, then deeply
analysis the problem of metadata interoperability from the aspects of semantic; grammar
and structure,including mapping; XML and RDF. and also summerd up the limitations of
sting existing technology solutions. On the basic of theses technologies presents a
management approach,metadata registry system.Then introduct foreign metadata
interoperability progress.
Keywords: metadata;metadata interoperability; metadata registry system
