DBpedia Mappings Wiki
This is the DBpedia Mappings Wiki. Its contents are used by the DBpedia extraction framework. The framework collects the mappings defined here and extracts Wikipedia content according to them in RDF.
Users can edit
- the DBpedia ontology schema (classes, properties, datatypes)
- the DBpedia infobox-to-ontology mappings
Mappings can be written for a variety of languages, while the ontology schema is ought to be used for all of them.
Mapping Example
This is how you write a simple infobox mapping.
Mapping:Infobox_actor
{{TemplateMapping
| mapToClass = Actor
| mappings =
{{ PropertyMapping | templateProperty = name | ontologyProperty = foaf:name }}
{{ PropertyMapping | templateProperty = birth_place | ontologyProperty = birthPlace }}
}}
This mapping extracts three information bits:
- the type information (Actor)
- the name of the actor
- the actor's place of birth.
Therefore, three RDF triples for each Infobox_actor in the English Wikipedia are extracted. For example for Vince Vaughn
dbpedia:Vince_Vaughn rdf:type dbpedia-owl:Actor . dbpedia:Vince_Vaughn foaf:name "Vince Vaughn"@en . dbpedia:Vince_Vaughn dbpedia-owl:birthPlace dbpedia:Minneapolis .

Prerequisites
If you like to edit the mappings or ontology schema this is what you need:
- a user account on this wiki (register)
- editor rights
- they will be given to you within a couple of days
- if not, lease ask for editor rights at dbpedia-discussion@lists.sourceforge.net Max: question: should we make this dbpedia-developers? I don't think the whole discussion list cares about Heinz from Königs Wusterhausen getting editor rights
- once you got editor rights, please provide some information about yourself on your user wiki page
- a namespace for the language you want to write mappings for
- if the namespace does not exist already (see the left side bar) please request it at dbpedia-discussion@lists.sourceforge.net
That's it!
That is all you need to kick-start. To get more detailed information, please follow the provided links.
Your contributions will be available
- in the DBpedia Live end point shortly after your edit (currently only for English)
- in the next DBpedia datasets release
Happy mapping!
