The project DALIA - Knowledge Base for "FAIR data usage and supply" produces and supplies an infrastructure for educational resources. An important contribution to this project is the development of a platform for teaching and training materials. It serves as a technical link between NFDI consortia and addresses an interdisciplinary research community. It is based on the DALIA Knowledge Graph which serves as an interlink of the heterogeneous and subject-specific teaching and learning materials. This poster provides the compilation of the controlled vocabularies concerning the human entities: contributors, users of the front-end, and their roles in accordance with the user roles of the platform. The focus here is on administrative metadata for human entities. Our aim is to create a hierarchy of simple metadata categories with mappings to other metadata schemas and a small (closed) core set for content curation, searching and harvesters.
