SaaS 플랫폼은 메타데이타를 기반으로 사용자에게 다중 사용자 지원 및 용이한 환경 설정으로 다양한 사용자 요구를 충족시키려 하고 있다. 따라서, 여러 고객이 하나의 서비스 인스턴스를 공유하고, 데이터베이스 안의 정보를 각자 관리할 수 있어 서비스로서 애플리케이션의 비용을 절감할 수 있다. 본 논문에서는 SaaS 플랫폼의 하나로 개발중인 SaaSpia 플랫폼에서 다중 사용자 지원 및 용이한 환경 설정을 위해 관리되어야 할 메타데이타를 알아보고, SaaSpia 애플리케이션에서 메타데이타 지원을 연구한다. SaaSpia 플랫폼에서 메타데이타는 일반 웹 애플리케이션을 SaaSpia 애플리케이션으로 변환하거나, 운용중인 SaaSpia 애플리케이션의 사용자별 설정 변경 시, 이용된다.
