AbstractThis posters is to anylze the LOD publishing and reusing the external LODs, and to suggest the future direction for LOD services in Korea. This poster is to analyze the LOD publishing and reusing the external LODs, and to suggest the future direction for LOD service in Korea. For this study, literature reviews and case study are carried on. For case study, KERIS, NLK, and KISTI are selected, which are the major organizations related to the library linked data. They have been publishing the linked open data of bibliographic records and authority data with interlinking the external LOD such as VIAF, LDS, BNB, ISNI, WorldCat, and so on. We analyzed the characteristics of three services – (1) subject domain, (2) volumes of bibliographic, authority, and subject data, (3) bibliographic, name, and subject ontology, (4) local ontology, and (5) interlinking external LOD. As the result for comparing three LOD services in aspect of ontology, FOAF, SKOS, DC, BIBO are common for all, and but MODS, DCTERMS, BIBFRAME, PRISM, and Bibtex are different ontology. Also all services have their own ontology – properties and classes. These local property and class has not consistency and has potential conflict between ontology. In aspect requirements for metadata, interoperability is very important requirement. The reason that locals developed their own ontology is lack of classes and properties for describing data for constructing LOD. Therefore LC BIBFRAME is developed as specific ontology for library sector.
