DCAT-AP-KR: 국내 데이터 포털의 상호운용을 위한 애플리케이션 프로파일

초록

Public data is increasingly critical for fostering data-driven economy. It can be improved through continuous feedback of supply and demand from data providers and consumers. Data consumers are able to freely use public data and create new values ​​by interlinking and consolidating among heterogeneous data from different data sources. Public institutions, which are data providers, should offer a set of datasets that consumers need, and provide methods for identifying datasets among data portals, which aim to create a new dataset by interlinking them. However, there are no standards or guidelines for metadata used in data portals operated by public institutions. This paper proposes DCAT-AP-KR, a set of metadata elements that can be commonly applied to data portals in Korea. It extracts metadata from data portals operated by public institutions and defines a set of common metadata through semantic analysis. The common metadata is added as a new vocabulary by applying the design principles of the DCAT-AP vocabulary. DCAT-AP-KR is a vocabulary specification that consistently represent the common metadata elements and values by applying the design principles of the DCAT-AP vocabulary.
