The currently established GUI and API-based metadata concepts will be extended by JSON-LD metadata schemas in the future. The benefit of using JSON-LD with community-agreed schemas is that they are better suited to provide semantically rich and domain-specific metadata, and linking of property values to defined terms from ontologies is more explicit. A first draft of such an implementation for samples was embedded in the samples' representation in the Chemotion repository (Figure , part 3; further information can be gained from SI section 5) and will be the subject of further discussion and improvement through the community of NFDI4Chem .
