Hi Rupert, Does dbpedia also have some equivalent like http://localhost:8080/entityhub/site/freebase/entity?id=http://rdf.freebase.com/ns/m.03qccxj&header_Accept=
I am trying http://localhost:8080/entityhub/site/dbpedia/query?id=http://dbpedia.org/resource/Category:Honda_Civic&header_Accept=which does not seems to be working. Also, I created dbpedia index with mapping.txt which contains the entry like: dbp-ont:industry | d=entityhub:ref dbp-prop:shortDescription | d=entityhub:text rdf:type | d=entityhub:ref But I am unable to fetch these properties from the resulting index file. The fieldQuery that I am using is: { "selected": [ "rdf:type", "rdfs:label", "dbp-ont:industry", "dbp-prop:shortDescription", ], "offset": "0", "limit": "5", "constraints": [{ "type": "text", "language": "en", "text": "Honda Civic", "field": "http:\/\/www.w3.org\/2000\/01\/rdf-schema#label" }] } Index is created from the following dumps: article_categories_en.nt.bz2 dbpedia_3.8.owl.bz2 infobox_properties_en.nt.bz2 instance_types_en.nt.bz2 pnd_en.nt.bz2 category_labels_en.nt.bz2 homepages_en.nt.bz2 infobox_property_definitions_en.nt.bz2 mappingbased_properties_en.nt.bz2 On Thu, Jun 13, 2013 at 12:06 PM, Manish Aggarwal <mani.i...@gmail.com>wrote: > Thanks Rupert for your answer.
