Wikibase RDF

Usage documentation

When the extension is enabled, Item and Property pages show a "Mapping to other ontologies" section. This section is located in between the "In more languages" and "Statements" sections.

Users with editing permissions can add, edit or remove mappings.

A mapping consists of a predicate and a URL. The predicate can only be one out of a preconfigured set of values. The URL has to be a valid URL.

Mapping predicates can be configured via the MediaWiki:MappingPredicates page by anyone with interface-admin permissions. You can also configure mapping predicates via PHP Configuration.
