In some cases, it might be possible that the returned graph could be a subgraph of a named graph / default graph of an RDF dataset. The client wants to discover if a query endpoint that exposes the relevant dataset, if one is available.For example, something like the following using the "search" link relation [3].------ HEAD /resource/Sri_Lanka Host: http://dbpedia.org ------ 200 OKLink: <http://dbpedia.org/sparql>; rel="search"; type="sparql", <http://fragments.dbpedia.org/2014/en#dataset>; rel="search"; type="ldf"... other headers ... ------ Best Regards, Nandana[1] http://swsa.semanticweb.org/sites/g/files/g524521/f/201507/DissertationOlafHartig_0.pdf[2] http://www.w3.org/TR/2014/REC-rdf11-concepts-20140225/#section-rdf-graph[3] http://www.iana.org/assignments/link-relations/link-relations.xhtml
