여러 분야에서 MRA(Metadata Registry Acess) 기반의 레거시 시스템들이 개발되었다. 그러나 구축된 MRA 레거시 시스템들은 표준을 엄격하게 준수하지 않아 메타데이터 간 충돌 문제가 발생한다. 메타데이터 표준 권고안인 ISO/IEC 11179에서는 표준적인 접근 보호 방법을 제공하지 않아 여러 가지 문제점을 초래한다. 일반적으로 SQL/MRA은 검색 및 매칭 기능만 지원할 뿐 MRA의 유효한 생성 및 안전한 보호 접근을 위한 연산을 지원하지는 않는다. 본 논문에서는 XMDR 기반의 시스템들에 안전하고 쉬운 접근제어를 보장하는 방법으로 PMCL을 제안한다. PMCL은 ISO/IEC 11179에 정의된 사용자 그룹의 역할과 권한을 미리 정의하여 사용자를 사용자 그룹에 할당한다. 이 기법은 편이성과 보안성을 증대시킬 수 있다.
The Legacy systems based on MRA have been developed in various areas. However, already existing MRA legacy systems do not strictly comply with the standard, resulting in conflicts between metadata. The metadata standard recommendation, ISO/IEC 11179, does not provide a standard guideline protection method. So there are many problems. In general, SQL/MRA only supports search and match functions, but does not support operations for effective creation and secure protection access of MRA. In this paper, PMCL is proposed as a way to ensure safe and easy access control for XMDR-based systems. PMCL assigns users to user groups by predefining the roles and privileges of the user groups defined in ISO/IEC 11179. This technique can increase ease and security.
