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) 
     1PREFIX cd:<http://tdwg-cd.wiki.opencura.com/entity/>
     2PREFIX cdt:<http://tdwg-cd.wiki.opencura.com/prop/direct/>
     3PREFIX cds: <http://tdwg-cd.wiki.opencura.com/entity/statement/>
     4PREFIX cdp: <http://tdwg-cd.wiki.opencura.com/prop/>
     5PREFIX cdq: <http://tdwg-cd.wiki.opencura.com/prop/qualifier/>
     6PREFIX cdps: <http://tdwg-cd.wiki.opencura.com/prop/statement/>
     7
     8SELECT ?item ?object ?count  WHERE {
     9  ?item cdt:P127 cd:Q124 .
    10  ?item cdp:P15 ?statement.
    11  ?statement cdps:P15 ?object.
    12  ?statement cdq:P106 ?count.
    13  SERVICE wikibase:label { bd:serviceParam wikibase:language "[AUTO_LANGUAGE],en". }
    14}
    

Get the total number of digitized specimen at MIDS level 1

The following query uses these:

  • properties: cd:digitalRecordType (P113) , cd:hasInstitution (P127) 
     1PREFIX cd:<http://tdwg-cd.wiki.opencura.com/entity/>
     2PREFIX cdt:<http://tdwg-cd.wiki.opencura.com/prop/direct/>
     3PREFIX cds: <http://tdwg-cd.wiki.opencura.com/entity/statement/>
     4PREFIX cdp: <http://tdwg-cd.wiki.opencura.com/prop/>
     5PREFIX cdq: <http://tdwg-cd.wiki.opencura.com/prop/qualifier/>
     6PREFIX cdps: <http://tdwg-cd.wiki.opencura.com/prop/statement/>
     7
     8SELECT ?item ?object ?count  WHERE {
     9  ?item cdt:P127 cd:Q124 .
    10  ?item cdp:P113 ?statement.
    11  ?statement cdps:P113 ?object.
    12  ?statement cdq:P123 ?count.
    13  ?statement cdq:P121 cd:Q120.
    14  SERVICE wikibase:label { bd:serviceParam wikibase:language "[AUTO_LANGUAGE],en". }
    15}
    

CD standard: Example Queries

Controlled vocabulary of preservation methods

This SPARQL query gives an overview of all preservation methods present in the wikibase.

The following query uses these:

  • properties: instance of (P1) 
    1PREFIX cd:<http://tdwg-cd.wiki.opencura.com/entity/>
    2PREFIX cdt:<http://tdwg-cd.wiki.opencura.com/prop/direct/>
    3
    4SELECT ?method ?methodLabel  WHERE {
    5  ?method cdt:P1 cd:Q41.
    6  SERVICE wikibase:label { bd:serviceParam wikibase:language "[AUTO_LANGUAGE],en". }
    7}
    

List of all Classes

This query provides you with a list of all available classes in the standard

The following query uses these:

  • properties: instance of (P1) 
    1PREFIX cd:<http://tdwg-cd.wiki.opencura.com/entity/>
    2PREFIX cdt:<http://tdwg-cd.wiki.opencura.com/prop/direct/>
    3
    4SELECT ?class ?classLabel  WHERE {
    5  ?class cdt:P1 cd:Q6.
    6  SERVICE wikibase:label { bd:serviceParam wikibase:language "[AUTO_LANGUAGE],en". }
    7}
    

List of all properties belonging to the ObjectGroup Class

This query creates a list of all properties belonging to the ObjectGroup class

The following query uses these:

  • properties: is part of (P3) 
    1PREFIX cd:<http://tdwg-cd.wiki.opencura.com/entity/>
    2PREFIX cdt:<http://tdwg-cd.wiki.opencura.com/prop/direct/>

    4SELECT ?prop ?propLabel  WHERE {
    5  ?prop cdt:P3 cd:Q3.
    6  SERVICE wikibase:label { bd:serviceParam wikibase:language "[AUTO_LANGUAGE],en". }
