Data Model

Initial efforts of the Helmholtz-KG implementation will focus on the representation of (meta)data describing the following digital core assets:

  • Documents / Publications
  • published Datasets
  • Software
  • Institutions
  • Infrastructure & Resources
  • Researchers & Experts
  • Projects

The representation of these instances will be semantically aligned with the schema.org and datacite vocabulary, a globally adopted standard offering a relaxed frame for the representation of heterogeneous data. Following the initial implementation the semantic expressiveness of the graph can be increased by integrating domain ontologies such as the HMC developed Helmholtz Digitization Ontology (HDO), which provides precise and comprehensive semantics of the concepts and practices used to manage digital assets.
