초록

메타데이터 레지스트리(Metadata Registry, MDR)는 데이터베이스 간 데이터 교환 및 공유를 위해 ISO/IEC에서 개발한 국제 표준이며, 의료 서비스, 서지, 환경 등 다양한 도메인에서 데이터 공유 및 통합을 위해 사용되고 있다. 그러나 MDR 표준은 메타데이터 등록 및 저장을 위한 메타모델만을 정의하고 있기 때문에 이 시스템들은 서로 다른 물리적 구조를 가지게 된다. 이로 인해 MDR 시스템 간 불일치가 발생하고 메타데이터의 상호운용을 위해 추가적인 비용이 발생한다. 이러한 문제를 해결하기 위해 ISO/IEC 13249-8 Metadata Registry Access (MRA)가 개발 중에 있으며, MRA는 상이한 MDR 시스템에 일관된 방법으로 접근할 수 있는 표준 인터페이스이다. 그러나 MRA는 MDR 표준에 정의되어 있는 개념 즉, 클래스 간 관계성을 고려하지 않는다. 이는 부정확한 결과를 생성할 수 있으며, 각 MDR 시스템의 물리적 구조를 고려하여 질의를 모델링하고 재작성하는 추가적인 비용이 발생한다. 이 논문에서는 클래스 간 관계성을 고려한 확장된 인터페이스 eMRA(Extened MRA)를 제안하며, 비교 평가를 통해 확장 인터페이스의 장점을 기술한다. eMRA는 MDR의 개념간 관계성을 정의하여 질의 모델링과 시스템의 참조무결성 측면에서 MRA보다 우수한 성능을 가진다.

Metadata registry (MDR) is the international standard, developed by ISO/IEC for exchange and sharing data between databases. Many MDR systems are used in diverse domains such as medical service, bibliography, environment for sharing and integrating data. However, those systems have different physical structures individually because the MDR standard defines only the metamodel for registering and storing metadata. It causes heterogeneity between the system structures and requires additional cost to maintain interoperability. ISO/IEC 13249-8 Metadata Registry Access (MRA) is developing as an international standard to provide a consistent access facility to data stored in different metadata registries. However, MRA does not consider the relationships between the concepts (classes) defined in the MDR specification. It causes that incorrect query results returned from MDR systems. It also requires additional cost of modeling and rewriting queries to reflect each physical model. Therefore, this paper suggests eMRA which considers the relationships between the concepts in MDR. The comparative evaluations are described to show the advantages of eMRA. eMRA has superior performance in query modeling and referential integrity than MRA defined by the relationship between the concept of MDR.
