DBpedia Mappings Wiki
This is the DBpedia Mappings Wiki. Its contents are used by the DBpedia extraction framework. Here, you can edit
- the DBpedia ontology schema (classes, properties, datatypes)
- the DBpedia infobox-to-ontology mapppings
The DBpedia extraction framework collects the templates defined here and extracts the Wikipedia content according to them in RDF. (learn how)
Mappings can be written for a variety of languages, while the ontology and 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!
