정보 표준화의 문제
 다양한 metadata 표준의 혼재
     MARC(Machine-Readable Cataloging) TEI(Text Encoding Initiative) DC(Dublin Core) ONIX(ONine Information eXchange) CERIF(Common European Research Information Format)  ………

 하나의 metadata 형식으로 모든 자원을 기술할 수 없으며 , 이미 다양한 형식의 metadata 표준들이 개 발되어 있고, 앞으로 더 광범위한 분야의 metadata 가 필요하게 됨
Metadata Registries 5

해결 방법
 metadata 통합 vs 다양한 metadata 인정
 해결 방법 사례
 Crosswalk  Warwick 구조  Metadata Registry

해결 방법
매핑 및 참조 테이블(Crosswalk)
 USMARC과 DC,TEI, EAD의 매핑 테이블, DC 와 다른 metadata 형식과의 참조 테이블, 공통 metadata 기술집합과의 매핑  문제점
• 의미상의 일치를 위해서는 전문가의 지적 능력 이 필요 • metadata의 잦은 수정으로 인한 유지관리의 부담 • 정확한 1:1 대응이 되지 않는 부분

해결 방법
 Warwick 구조
 공존하는 다양한 metadata 형식의 interoperability 지원  W3C에서 개념적인 차원의 통합 구조인 RDF 를 개발, 구현

Metadata Registries
 metadata
 data that defines and describes other data

 Metadata Registry(MDR)
 an information system for registering metadata

 Metadata is also data, so metadata may be stored in a database. A database of metadata that supports the functionality of registration is a Metadata Registry.
