How can I execute query with labels preference order? The way to prefer one label to the other can be done as follows: Have a procedure which returns preference order: create procedure lbl_order (in p any) { declare r int; r := vector ( 'http://www.w3.org/2000/01/rdf-schema#label', 'http://xmlns.com/foaf/0.1/name', 'http://purl.org/dc/elements/1.1/title', 'http://purl.org/dc/terms/title', 'http://xmlns.com/foaf/0.1/nick', 'http://usefulinc.com/ns/doap#name', 'http://rdf.data-vocabulary.org/name', 'http://www.w3.org/2002/12/cal/ical#summary', 'http://aims.fao.org/aos/geopolitical.owl#nameListEN', 'http://s.opencalais.com/1/pred/name', 'http://www.crunchbase.com/source_description', 'http://dbpedia.org/property/name', 'http://www.geonames.org/ontology#name', 'http://purl.org/ontology/bibo/shortTitle', 'http://www.w3.org/1999/02/22-rdf-syntax-ns#value', 'http://xmlns.com/foaf/0.1/accountName', 'http://www.w3.org/2004/02/skos/core#prefLabel', 'http://rdf.freebase.com/ns/type.object.name', 'http://s.opencalais.com/1/pred/name', 'http://www.w3.org/2008/05/skos#prefLabel', 'http://www.w3.org/2002/12/cal/icaltzd#summary', 'http://rdf.data-vocabulary.org/name', 'http://rdf.freebase.com/ns/common.topic.alias', 'http://opengraphprotocol.org/schema/title', 'http://rdf.alchemyapi.com/rdf/v1/s/aapi-schema.rdf#Name', 'http://poolparty.punkt.at/demozone/ont#title' ); if (isiri_id (p)) p := id_to_iri (p); r := position (p, r); if (r = 0) return 100; return r; } ; Execute the following query: SPARQL DEFINE input:inference "facets" SELECT ?o WHERE { <http://uriburner.com/about/id/entity/http/www.linkedin.com/in/kidehen#CV_mfrTl4s6Jy> virtrdf:label ?o ; ?p ?o . } ORDER BY (sql:lbl_order (?p)); Or execute the following query using sql: SELECT __ro2sq (O), lbl_order (P) FROM RDF_QUAD table option (with ''facets'') WHERE G = __i2id (?)
