Abstract

This study aims to develop vocabulary encoding schemes to improve the data quality and educational usability of the “Dokseoro DLS” school library catalog system. The current system lacks standardized vocabularies, resulting in data inconsistency and limited instructional value. Based on literature review, case analysis, and expert consultation, encoding schemes for 15 metadata elements were proposed—seven existing and eight newly introduced elements linked to the 2022 revised curriculum. Six schemes were adapted from existing standards such as KORMARC and national authority files, while nine were newly developed to suit the school environment. This study contributes to enhancing the standardization and educational function of school library metadata.
