Abstract

This study conducted comparative analysis of the bibliographic descriptions in KCR5 and KCR4, and the results are as follows. First, structurally, KCR4 is based on ISBD by media type, while KCR5 is based on FR concept model. In terms of table of contents, KCR5 added access points and bibliographic relationship sections. Second, while KCR4 defines both the semantic and syntactic aspects of elements, KCR5 defines only the semantic aspects. Third, there are many changes in the main bibliographic descriptions of KCR4, including media type, material specific area, material description area, and note area. In particular, KCR5 newly established entities related to authority data, such as work, expression, person, family and corporate body. Forth, as can be seen from the analysis of actual KCR5 bibliographic description cases, there are many differences from KCR4 in recording entity properties, recording entity relationships, and creating entity access points.
