이 연구는 디지털 도서관에 실제로 사용된 메타데이터의 요소와 활용을 분석하여 의미적 상호운용성 향상 요인을 고찰하는 데 목적이 있다. 이를 위해 그린스톤 기반의 78종의 디지털 도서관에서 실제로 사용한 메타데이터 요소를 동질 정보 커뮤니티로 세분하여 분석하였다. 동질 정보 커뮤니티내 디지털 도서관에서 사용된 메타데이터 요소를 크로스워킹하고, 각 요소들의 활용 및 활용 수준을 분석하였다. 그 결과 동일 정보 커뮤니티 내에서 중복되는 핵심 메타데이터 요소는 25% 미만으로 나타났다. 이들 핵심 메타데이터 요소는 요소 명칭과 활용에 있어서 불일치하는 문제점이 고찰되었으며, 메타데이터 요소 활용의 수준에 있어서도 무결점과 완결성 면에서 상이한 측면이 밝혀졌다.
The purpose of this study is to examine semantic interoperability in terms of metadata elements and content designation in context of digital libraries. This study analyzed 78 digital libraries implemented using Greenstone application with respect to metadata elements and their content designation. Using crosswalks of digital libraries' metadata elements, and comparisons of content designation in elements, this study identifies three aspects which can impact semantic interoperability. First, there were less than 25% core metadata elements even within homogeneous information communities. Second, discrepancy exists between element names and their usage. Third, different levels were identified when assigning content to designated elements in terms of integrity and completeness.
