The DBpedia ontology is based on OWL and forms the structural backbone of DBpedia. It describes classes, e.g. person, city, country, and properties, e.g. birth place, longitude. Information in Wikipedia articles is then mapped via the above described mapping to this ontology. Most prominently, many Wikipedia pages use so called infoboxes. For instance, the English wikipedia article about [http://en.wikipedia.org/wiki/London London] contains a "settlement infobox". This infobox may be mapped to e.g. the class "populated place" (see [[OntologyClass:PopulatedPlace|PopulatedPlace]]) in the DBpedia ontology and the attributes in the infobox are mapped to properties in the DBpedia ontology. <!-- Please see the [http://en.wikipedia.org/wiki/Template:Infobox_settlement/doc documentation of the settlement infobox] for details. --> This way, a unified view over all data in infoboxes can be obtained. Since this information conforms to Semantic Web standards, it can be queried and combined by a broad range of tools in a useful way. This increases the value of information entered by the Wikipedia community. | The DBpedia ontology is based on OWL and forms the structural backbone of DBpedia.

The DBpedia ontology is based on OWL and forms the structural backbone of DBpedia. It describes classes, e.g. person, city, country, and properties, e.g. birth place, longitude. Information in Wikipedia articles is then mapped via the above described mapping to this ontology. Most prominently, many Wikipedia pages use so called infoboxes. For instance, the English wikipedia article about London contains a "settlement infobox". This infobox may be mapped to e.g. the class "populated place" (see PopulatedPlace) in the DBpedia ontology and the attributes in the infobox are mapped to properties in the DBpedia ontology. This way, a unified view over all data in infoboxes can be obtained. Since this information conforms to Semantic Web standards, it can be queried and combined by a broad range of tools in a useful way. This increases the value of information entered by the Wikipedia community.
A listing of all classes, properties and datatypes (units of measurement) used by the DBpedia ontology is found below:
- Ontology Classes - OWL classes and their definitions
- Ontology Properties - OWL Object and Datatype properties
- Datatypes
Tutorials
Tools
- Ontology View. The ontology view gives you an overview about the current shape of the DBpedia ontology.
- Ontology Validator. When you are editing a mapping, there is a validate button on the bottom of the page. Pressing the button validates your changes for syntactic correctness and highlights inconsistencies such as missing property definitions.
- MappingTool. The DBpedia MappingTool is a graphical user interface that supports users to create and edit mappings.
