Wikibase implementation of the TDWG Latimer Core standard

This Wikibase is part of the non-normative documentation of the Latimer Core standard. It contains all current properties defined in the standard and the advised schema to use those properties.

Wikibase model

This Wikibase contains the properties defined in the Latimer Core 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: FossilSpecimens (Q26)


Collection modelling

Example institutional record

As an example, we modeled the FMNH institutional collection 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 specimens:

The following query uses these:

PREFIX lcq: <http://latimer-core.wikibase.cloud/prop/qualifier/>
PREFIX lcps: <http://latimer-core.wikibase.cloud/prop/statement/>

SELECT ?item ?itemLabel ?measfact ?value ?unit
        { 
            VALUES ?item {lc:Q62}
            OPTIONAL {?item lct:P9 ?measfact .}
            OPTIONAL {?measfact lct:P79 ?value .}
            OPTIONAL {?measfact lct:P78 ?unit .}
            SERVICE wikibase:label { bd:serviceParam wikibase:language "[AUTO_LANGUAGE],en". }
        }

Get the total number of digitized specimen at MIDS level 1

The following query uses these:

Controlled vocabulary of preservation methods

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

The following query uses these:

PREFIX lc:<http://latimer-core.wikibase.cloud/entity/>
PREFIX lct:<http://latimer-core.wikibase.cloud/prop/direct/>

SELECT ?method ?methodLabel  WHERE {
  ?method lct:P134 lc:Q25.
  SERVICE wikibase:label { bd:serviceParam wikibase:language "[AUTO_LANGUAGE],en". }
}
