sdg:endpoint
sdg:endpoint names where the declared resource can be queried. Two document types carry it, with different value shapes:
- On a Constellation Graph, the value follows the adapter kind: for in-process graphs it is a
urn:cog:graph:*token — the lexicon'surn:cog:graph:sparqdown-lexicon— which the host process resolves to the in-memory endpoint rather than dialling a network address. The docs server fronts such graphs over HTTP itself (the workspace reaches the lexicon through/api/cog/sparql). - On a Source Definition, the value is always the source's resolvable SPARQL endpoint URL — never a URN or other indirection. A claim written against a registered source cites this resolved URL directly as its
sd:claimSource, never the SourceDefinition document's own IRI.
Usage
- Domain:
sdg:ConstellationGraphorsdg:SourceDefinition. Range: an endpoint IRI — a URN for in-process ConstellationGraph adapters (still a URN forcog:RemoteHttpAdaptergraphs — the base URL is host configuration, not document content), always a network URL on a SourceDefinition. One per declaration.
