WikidataR2RExtractor

class WikidataR2RExtractor extends JsonNodeExtractor

Created by ali on 10/26/14. This extractor maps wikidata statements to DBpedia ontology wd:Q64 dbo:primeMinister wd:Q8863.

In order to extract n-ary relation mapped statements are reified. For reification unique statement URIs is created. Mapped statements reified on the form of wd:Q64_P6_Q8863 rdf:type rdf:Statement. wd:Q64_P6_Q8863 rdf:subject wd:Q64 . wd:Q64_P6_Q8863 rdf:predicate dbo:primeMinister. wd:Q64_P6_Q8863 rdf:object wd:Q8863.

Qualifiers use same statement URIs and mapped on the form of wd:Q64_P6_Q8863 dbo:startDate "2001-6-16"xsd:date. wd:Q64_P6_Q8863 dbo:endDate "2014-12-11"xsd:date.
