하나의 metadata 형식으로 모든 자원을 기술할 수 없으며 , 이미 다양한 형식의 metadata 표준들이 개발되어 있고 , 앞으로 더 광범위한 분야의 metadata 가 필요하게 됨

정보 표준화의 문제정보 표준화의 문제


해결 방법해결 방법 metadata 통합 vs 다양한 metadata 인정

해결 방법 사례CrosswalkWarwick 구조Metadata Registry


해결 방법해결 방법매핑 및 참조 테이블 (Crosswalk)

USMARC 과 DC,TEI, EAD 의 매핑 테이블 , DC 와 다른 metadata 형식과의 참조 테이블 , 공통 metadata 기술집합과의 매핑

문제점 •의미상의 일치를 위해서는 전문가의 지적 능력이

필요•metadata 의 잦은 수정으로 인한 유지관리의 부담•정확한 1:1 대응이 되지 않는 부분

Metadata RegistriesMetadata 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.
