Issue 461: Attribute Assignment of .1 properties

Starting Date: 
Working Group: 

Posted by Robert Sanderson on 3/12/2019

Dear all,


With the addition of P177 assigned property type, we can associate a relationship with an Attribute Assignment. This is wonderful, as it lets us be clear about the relationship that the attribute assignment is expressing.

However, some properties are 3-tuples, as expressed in the first order logic, with a .1 property that qualifies the relationship further.  We currently cannot add the qualifier to the attribute assignment when using a property that allows these, and to be able to do so would be very beneficial.


To project the example of P14 into an Attribute Assignment:



  The painting of the Sistene Chapel (E7) was carried out by Michaelangelo Buonaroti (E21) in the role of master craftsman (E55).


A very typical attribution of which most organizations have many instances.


An Attribute Assignment could look like:


<aa1> a E13_Attribute_Assignment ;

  P140_assigned_attribute_to [

        a E7 Activity ;

        rdfs:label “Painting of the Sistene Chapel Activity” ] ;

  P141_assigned [

        a E21_Person ;

        rdfs:label “Michaelangelo Buonaroti” ] ;

  P177_assigned_property_type <P14_carried_out_by> ;

  Pxxx_assigned_property_of_property_type [

      a E55_Type ;

      rdfs:label “master craftsman” ] .


Or some other less verbose name for the new property.


Many thanks for your consideration, fellow SIG-folks.

Current Proposal: 

In the 48th CIDOC CRM and 41st FRBR CRM sig meeting (virtual), the sig discussed about adding qualifiers to the attribute assignment when using a property that allows these, and which would be very beneficial and assigned to MD and RS to write a short text to describe the alternatives for assigning .1 properties and discuss materialization of the referred property.

October 2020

In the 53rd CIDOC CRM & 46th FRBRoo SIG meeting, the SIG reassigned the HW to RS and MD. It is about adding a qualifier to an attribute assignment. Postpone the issue, until HW has been turned in.
