Invited Talk: Metadata in Research Data Management

Metadata has long been recognized as a fundamental component of research data management and reuse. However, the extent to which metadata practices facilitate data reuse remains insufficiently explored. This study investigates metadata practices in research data management across scientific disciplines. Data were collected from the Data Citation Index.. Five categories of metadata elements were identified and analyzed. The findings reveal that descriptive metadata and author-related information were the most prevalent across datasets, whereas persistent identifiers such as DOIs and ORCID iDs were used infrequently. These results contribute to a deeper understanding of metadata practices and highlight key metadata elements that may support the reuse of research data.
