The research and development on Web of Data to realize the opening and sharing of diverse, heterogonous data on the Web has been actively accomplished. As a standard data model for this effort, LOD (Linked Open Data) based on ontology has been proposed. A specialized instance generation system is vital to the development of LOD-based system effectively. This paper implements i-Manager as an appropriate environment for the development of LOD instances, considering the requirements of LOD systems and the practical development environment of the diverse application domains. i-Manager separates the instance layer from the ontology layer by way of LOD Interface Sheet (LIS) and implements the specialized functions requested in LOD instance development, such as instance edit/store, visualization and SPARQL query processing. This paper proposes a new approach for LOD instance development, and i-Manager can be applied for the practical LOD development environment in the diverse application areas.

웹상에서 이질적 형태의 다양한 데이터를 개방, 공유하여 차세대 데이터웹을 실현하고자 하는 연구개발이 활발하게 수행되고 있다. 이를 위해 표준 데이터 모델로 온톨로지 기반의 LOD가 개발되었다. LOD기반 시스템을 효과적으로 개발하기 위해서는 전문화된 인스턴스 생성 시스템이 필수적으로 요구되고 있다. 본 논문은 LOD 시스템의 요구사항과 다양한 응용분야의 개발환경을 고려하여, LOD 인스턴스 개발에 적합한 i-Manager를 설계 구현하였다. i-Manager는 LOD 인터페이스 시트를 이용해서 온톨로지와 인스턴스 계층을 분리하고, 인스턴스 편집/저장, 시각화, LOD 질의 처리 등 LOD 인스턴스 개발에 전문화된 기능들을 제공한다. 본 논문은 LOD 인스턴스 개발의 새로운 방향을 제시하고 있으며, 구현된 i-Manager는 다양한 분야에서 LOD 개발 범용환경으로 활용할 수 있다.
