== Wikibase model == | == Wikibase model == | ||
to be | This Wikibase contains the properties defined in the Collection Description standard. In case a controlled vocabulary is needed for a property, this is modelled as follows: | ||
* The property is pointing to an 'Item' | |||
* This item should be an instance of a 'Concept'. See this example: {{Q|46}} | |||
Not all concepts and controlled vocabulary term are already present in the Wikibase. So when adding your institutional data, it might/will be necessary to add new terms to the Wikibase. | |||
== Example Queries == | |||
=== Controlled vocabulary of preservation methods === | |||
This SPARQL query gives an overview of all preservation methods present in the wikibase. | |||
