Abstract: ObjectiveTo study the application of Metadata in search and find data with different structue in medical data resources share.MethodsStudy the definition and character of metadata, establish the metadata standard and directory service system to execute the data search service.ResultsThe Directory Service System based on the method of metadata has been developed, in which the data search service can be realized. ConclusionThe Directory Service System based on the method of metadata has been developed, in which the data search service can be realized. Conclusions It's a effective way to search and find data with different structue using method of metadata, and it is a important way to realize medical data resource share.
