Examples
Worked examples
- Is an instance
A DMP serialisation whose '@context' resolves to the published RDA Common Standard vocabulary and whose dataset entities are joinable to DataCite DOIs.
- Is an instance
A SPARQL query combining DMP graphs with funder-grant graphs.
Counter-examples
Looks similar, but isn't
- Not an instance
Plain RDA-CS JSON without a '@context' (still useful, but not linked-data).
- Not an instance
DCAT-AP (a different vocabulary for catalogues).
Editorial commentary
DMP RDA-JSON-LD is a JSON-LD context and ontology rendering of the RDA DMP Common Standard: it adds an “@context” that maps the standard’s properties (project, dataset, contributor, host, and so on) to dereferenceable identifiers (IRIs) in a published vocabulary. That extra layer is what lets a plan’s entities be treated as linked data — queried, merged, and reasoned over with standard semantic-web tooling such as SPARQL or SHACL — rather than just parsed as an isolated JSON document.
The practical payoff shows up in cross-system integration: a DMP expressed in RDA-JSON-LD can be joined directly to the OpenAIRE Research Graph, or merged with an institutional CRIS’s own knowledge graph, because its dataset entities resolve to the same kind of identifiers (DOIs, ORCID iDs) those graphs already use. Most research offices will never author RDA-JSON-LD by hand — it is produced automatically by a DMP tool’s export function — but it is worth recognising as the reason a “linked data” or “@context” field appears in an exported DMP file.
How it differs from adjacent DMP concepts
- vs. RDA DMP Common Standard — the Common Standard defines the entities and properties; RDA-JSON-LD is a specific serialisation of those entities as linked data, not a separate standard.
- vs. DMP machine-readable expression — RDA-JSON-LD is one linked-data flavour of a machine-readable expression; plain RDA Common Standard JSON without the “@context” is machine-readable but not linked data.
