Long-term goals
- All languages use IRIs
- DBpedia chapters
| 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 |
Current deviations from these rules
In the past, we did not follow these rules. For backwards compatibility, we will allow some deviations for a while.
- 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 |
Notes
- 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.
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)
