D4.3.1 Technical requirements for metadata in NFDI4Energy services

Metadata is a key cornerstone of research data management. However, the proper use of metadata for
both developers and users is not yet sufficiently developed. This deliverable shall present the current
state of technical requirements that we encourage as NFDI4Energy. Its goal is to create guidance
within the energy domain on how to interact with metadata and how to build systems and repositories
that handle metadata. We also reflect on these kinds of requirements from other NFDI consortia,
to show the similarities and differences that might arise from the different maturity and use cases
throughout the different domains. The presented requirements reflect the state at the publication
date, but will be further updated and evolved in the GitHub1 repository that serves as a metadata
requirement collection platform (https://github.com/NFDI4Energy/metadata-requirements).
The repository is also meant for collecting requirements about metadata modules that are specific to
certain dataset types. This requirement collection process will continue in the community over the
next years. In order to contribute, use the GitHub issues in the repository to make your improvement
ideas known.
