Semantic Wikibase for Wikibase
Use Wikibase data in your Semantic MediaWiki.
Allows you to get the best of both worlds. Data added in the form of Wikibase items and properties is automatically made available in Semantic Mediawiki (SMW). This means you can use it with all SMW functionality, such as embedded visualizations, autocompletion in forms, export in RDF/JSON/CSV/etc and more.
Professional Wiki created Semantic Wikibase. We are Wikibase developers that provide professional Wikibase software development and Wikibase hosting.
We thank Frans AL van der Horst for funding initial development.
Usage documentation
Data part of Wikibase Items and properties gets translated to Semantic MediaWiki property value pairs.
Labels, descriptions, IDs, etc
Translated data in the form Wikibase datamodel element => SMW property name (SMW property type)
- EntityId => Wikibase ID (Text)
- Labels => Wikibase label (Monolingual text)
- Descriptions => Wikibase description (Monolingual text)
- Aliases => Wikibase alias (Monolingual text)
Statements
When a statement is translated, only the value of the "main snak" is stored in SMW.
The SMW property name is the ID of the Wikibase property, for instance P42.
The label of the Wikibase property gets added as alias.
This means both [[P42::+]] and [[Capital city::+]] are valid in SMW queries.
Deprecated statements are never translated. Normal statements are not translated if there are preferred statements. The SMW property type is based on the Wikibase property type. Only statements with a supported property type are translated.
