Quantitative assessment of metadata collections of research data repositories

Structured metadata enable and facilitate research data discovery and reuse. Although metadata records are often created and maintained at research data repositories, existing research offers limited insights into the relationship between repositories and metadata for research data. Addressing this issue, this presentation covers the results of a joint analysis of two data sources, DataCite and re3data, examining aspects of metadata quality in the context of re- search data. Properties of metadata records were analyzed and put in relation with char- acteristics of the repositories entrusted with their curation (for example, the certification status). In addition, metadata practices at repositories were examined based on changes to metadata records, demonstrating that metadata records are dynamic objects.
