The Biobank has been developed to allow that authorized researchers can search and access CDA(Clinical Document Architecture) documents for the clinical information associated with particular human biomedical resources of their interests. It needs both of definition and management system of metadata of CDA document related to human biomedical resource. In addition, it should support interoperability among biobanks. In this paper we propose a registry system for the biobank based on the above requirements. It manages and stores extended metadata of registered CDA documents, which extends IHE(Integrating the Healthcare Enterprise) XDS(Cross Enterprise Document Sharing) Document metadata. For interoperability among biobanks, it uses ebXML(Electronic Business using eXtensible Markup Language) as a base framework. In the implementation, we adopted ORM(Object-relational mapping) tool for database-independence, Java for platform-independence, and RESTful (Representational State Transfer) web services for accessibility from heterogeneous operating system. With this registry system managing extended metadata of CDA documents, we can use CDA documents efficiently. In performance evaluation, it is shown that this system is faster in registration time, but slower in query response time than ebxmlrr, open-source registry based on SOAP(Simple Object Access Protocol); therefore, performance in querying should be improved.
