Metadata Application Profile

The creation of the VaxStats’ metadata schema was guided by the needs of users, with regard to both consumption and submission of data. As the primary focus of the VaxStats’ repository is government created documents and reports, the metadata schema was modeled after Project Open Metadata’s, whose primary purpose is to describe datasets and other publications produced by government agencies. VaxStats’ schema differs from Project Open metadata’s primarily by way of which fields are required.

‌VaxStats’ metadata schema is modeled according to the Data Catalog Vocabulary (DCAT), an RDF vocabulary which uses terminology from the Dublin Core Terms vocabulary. It is intended for use in government repositories, and was especially suited to the needs of VaxStats user community.
