WikidataRawExtractor

class WikidataRawExtractor extends JsonNodeExtractor

Created by ali on 10/26/14. Raw wikidata statements extracted on the form of wd:Q64 wikidata:P6 wd:Q8863.

In order to extract n-ary relation 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 wikidata:P6. wd:Q64_P6_Q8863 rdf:object wd:Q8863.

Qualifiers use same statement URIs and extracted on the form of wd:Q64_P6_Q8863 wikidata:P580 "2001-6-16"xsd:date. wd:Q64_P6_Q8863 wikidata:P582 "2014-12-11"xsd:date.
