DBpedia domains and URIs

Long-term goals

• All languages should use IRIs

Items	IRI pattern
Ontology classes and properties	http://dbpedia.org/ontology/Xyz
Datatypes	http://dbpedia.org/datatype/xyz
Resource IRI for http://xx.wikipedia.org/wiki/Xyz	http://xx.dbpedia.org/resource/Xyz
Property extracted by generic template extractor	http://xx.dbpedia.org/property/xyz

Deviations from these rules for backwards compatibility

• English and French use URIs, not IRIs. DBpedia Berlin will publish additional datasets with IRIs, but the main datasets will use URIs.

Items	IRI pattern
Resource URI for http://en.wikipedia.org/wiki/Xyz	http://dbpedia.org/resource/Xyz
Property extracted by generic template extractor from http://en.wikipedia.org/ pages	http://dbpedia.org/property/xyz

Implementation details

• During the extraction, the framework will use http://xx.dbpedia.org/ IRIs for all languages. Different serializers will serializes them differently, according to some rules
  • convert en.dbpedia.org to dbpedia.org
  • convert IRIs to URIs for some languages (in subjects, predicates and objects)
