Issue 556: Content of the minimal vocabularies for restricting the CIDOC CRM Types

Starting Date: 
Working Group: 

In the 50th joint meeting of the CIDOC CRM SIG and SO/TC46/SC4/WG9; 43nd FRBR – CIDOC CRM Harmonization meeting, the SIG decided to start a new issue where to dscuss the content of the minimal vocabularies required for restricting the CIDOC CRM Types. 

Outline: Provide content for a recommended CRM-SIG vocabulary based on reviewing CRM scope notes and using the outcome of issue 496.

No HW assignment until 496 is resolved. 

June 2021

Current Proposal: 

In the 53rd CIDOC CRM & 46th FRBRoo SIG meeting, the SIG returned to Issue 556 to establish what the next steps are and assign HW, since 496 has been resolved. 

So far: 

  • TV has proposed a list of classes of the CRM, for which recommending a type would be useful. 
  • MD has suggested providing recommendations for (a) the types mentioned in properties the range of which is an instance of E55 Type (or a specialization thererof), and by extension all the .1 properties, (b) the types referred to (or implied) in the scope notes of classes and properties. 


  1. closely-read the scope notes of CRM classes/properties in order to determine what ontological distinctions can be implemented through the use of types, 
  2. go through the deprecated classes to determine whether their content and labels match classifications implemented in other known vocabularies (to check for the next meeting), 
  3. identify domain-specific vocabularies and standardized vocabularies that are relevant for the CRM.


Everyone in agreement, HW assigned to

  • TV: check the classes he has identified for type-recommendations 
  • WS: check types of E4 Period (also settlements qua E7 Activity) and with vocabs from the DAI.
  • MD: check the deprecated classes
  • RN: skos vocabularies that they work with at the NFDI 

To be discussed again in the next Sig meeting.
