Tasks

The HMC Hubs build a metadata community in their respective research area. They serve and support Helmholtz centers, projects and research staff in all aspects of research data management across the entire data cycle, mainly in providing rich metadata.

Imparting knowlege on metadata is essential, particularly on vocabularies, standards, ontologies, and repositories, but also on existing tools for the management of researchd ata and for their easy and comfortable availablity. Participating in the development of training materials and the delivery of relevant courses to the community of the research domain energy is an important task for the hub.

In collaboration with FAIR Data Commons the Energy Hub is also engaged in the development of a metadata concept taking into account specific prerequisites of the research area Energy. This is based upon:

• The FAIR principles, which provide guidance for Findability, Accessibility, Interoperability, and Reusability of data

• FAIR Digital Objects (FDO), linking FAIR principles with the concept of Digital Objects

• The design and development of interfaces for data access

• The use of existing standards, vocabularies, and ontologies

• The use of ontologies and knowledge graphs for the description of research data with metadata

• AI support in the form of Large Language Models (LLM) in the processing of ontologies and knowledge graphs

• Providing provenance data together with research data

• The use of tools throughout the research data and metadata life cycle

Use cases provide a framework for testing existing concepts and developing new ones. They also contribute significantly to enhancing the expertise available in the Hub. Use cases are therefore also essential for the knoledge impartment.
