Abstract

The purpose of this study is to propose a W3C standard, DCAT, to manage and service dataset that is becoming increasingly important as new knowledge information resources. To do this, we first analyzed the class and properties of the four core classes of DCAT. In addition, I modeled and presented a system that can manage and service various data sets based on DCAT in digital library. The system is divided into source data, data set management, linked data connection, and user service. Especially, the DCAT mapping function is suggested in dataset management. This feature can ensure interoperability of various datasets.

본 연구는 새로운 지식정보자원으로 중요성이 높아지고 있는 데이터셋을 관리 서비스하기 위해 W3C 표준인 DCAT 활용방안을 제시하고자 하였다. 이를 위해 먼저 DCAT을 구성하는 8개의 클래스 중 핵심 클래스 4가지를 중심으로 클래스와 속성을 분석하였다. 또한 디지털도서관에서 DCAT을 기반으로 다양한 데이터셋을 관리 서비스할 수 있는 시스템을 모델링하여 제시하였다. 이 시스템은 원천데이터, 데이터셋 관리, 링크드 데이터 연결, 이용자 서비스로 구분하여 구성하였으며 특히 데이터셋관리에서는 DCAT 매핑 기능을 제시하여 다양한 데이터셋 서비스와 상호운용성 확보가 가능하도록 하였다.
