Hi all, As one of the persons in charge of the dataset that Vishal has pointed out to, and responding to Hugh's comment, you will actually find a description of this specific dataset at: http://datahub.io/dataset/culturalinkeddata In fact, according to our own methodological guidelines for generating Linked Data (that is, eating our own dog food), we always recommend generating, as commented by Hugh, the sitemap.xml and a void description for all our datasets, registering them to the CKAN registry. The data that is available in that SPARQL endpoint is now migrated to http://datos.bne.es/ (it is data from the Spanish National Library), and the void description is at http://datos.bne.es/void/bne.ttl Regards, Oscar -- Oscar Corcho Ontology Engineering Group (OEG) Departamento de Inteligencia Artificial Facultad de Informática Campus de Montegancedo s/n Boadilla del Monte-28660 Madrid, España Tel.
