Wikibase implementation of the Collection Description (CD) standard

This Wikibase will be used to demonstrate the current CD standard using real data.

The data standard is currently under development. This development is done in GitHub

Wikibase model

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: dried pinned (Q46)

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.

Collection modelling: example

Example collection

As an example, we modeled the herbarium of Meise Botanic Garden in the Wikibase. The main components of the example description are:

Example Queries on collections

Get the total number of curatorial objects

This query gives the total amount of specimen:

The following query uses these:

  • properties: cd:objectType (P15) , cd:hasInstitution (P127) 
     1 PREFIX cd:<http://tdwg-cd.wiki.opencura.com/entity/>
     2 PREFIX cdt:<http://tdwg-cd.wiki.opencura.com/prop/direct/>
     3 PREFIX cds: <http://tdwg-cd.wiki.opencura.com/entity/statement/>
     4 PREFIX cdp: <http://tdwg-cd.wiki.opencura.com/prop/>
     5 PREFIX cdq: <http://tdwg-cd.wiki.opencura.com/prop/qualifier/>
