Abstract

This study examines the implementation and utilization strategies of accessibility metadata in digital publications and proposes a structural and policy model for its adoption in Korea. Accessibility metadata plays a key role in enhancing the inclusivity of the digital publishing ecosystem and ensuring the right to choose accessible content for information-vulnerable groups. The study confirmed that the effective implementation of accessibility metadata requires technological integration and user interface (UX) visualization strategies based on international standards such as EPUB Accessibility 1.1, ONIX 3.0, and MARC 21. To this end, the study analyzed global standards and overseas implementation cases and conducted a survey involving disabled person users and professionals from the publishing, distribution, and library sectors in Korea. The results indicated a high demand for accessibility metadata, while its actual visibility and user-centered presentation on digital publishing platforms remained insufficient. Accordingly, the study proposes a technical model that integrates accessibility metadata structures across the publishing supply chain, the introduction of a Korean certification system for accessible eBooks (KACA), and the establishment of a visualization guideline for UX presentation of accessibility information. This research provides foundational data for the institutionalization and technological advancement of accessibility in the Korean digital publishing environment.
