Graph Queries on Metadata

SPARQL Graph Queries (CONSTRUCT and DESCRIBE) can be applied to metadata graphs. The graph query must be supplied as a URL-parameter graphQuery when fetching the metadata graph. A graph query can be applied to a simple metadata graph and traversal results (see separate KB entry on Traversal). The query must be URL-encoded.



The URL-decoded graph query of the example is:

PREFIX es: <>
PREFIX dct: <>
CONSTRUCT { ?s es:name ?o } WHERE { ?s dct:title ?o }
