DBpedia domains and URIs: Difference between revisions

Revision as of 22:36, 14 May 2012

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
Properties extracted by generic template extractor	http://xx.dbpedia.org/property/xyz

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
Properties extracted by generic template extractor from http://en.wikipedia.org/ pages	http://dbpedia.org/property/xyz

We used to map page titles from non-English Wikipedias to IRIs using the inter-language link to the English Wikipedia. If there was no such inter-language, we did not extract any data from the page. That was because we used URIs like http://dbpedia.org/resource/Xyz for all languages and had to 'normalize' them. We will not do that anymore - we use http://xx.dbpedia.org/resource/Xyz IRIs.

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)

+* We used to map page titles from non-English Wikipedias to IRIs using the inter-language link to the English Wikipedia. If there was no such inter-language, we did not extract any data from the page. That was because we used URIs like <nowiki>http://dbpedia.org/resource/Xyz</nowiki> for ''all'' languages and had to 'normalize' them. We will ''not'' do that anymore - we use <nowiki>http://xx.dbpedia.org/resource/Xyz</nowiki> IRIs.
