Issue 127: Properties of E13 Attribute Assignment

Starting Date:

Done

Background: 

Following some discussion, we propose here a possible extension to the CIDOC CRM version 3.4.1. It is merely conservative, i.e. it does not invalidate any previous instance. It provides a better base to formalize the idea to be able to indirect existing properties declared in the CRM by the activity of assigning it. The next meeting should decide, if this construct is actually regarded necessary for the standard.

Current Proposal: 

E13 Attribute Assignment

Subclass of: E7 Activity
Superclass of: E14 Condition Assessment
E15 Identifier Assignment
E16 Measurement Event
E17 Type Assignment
Scope note: This class comprises the actions of making assertions about properties of an object or any relation between two items or concepts. This class serves the documentation of how the respective assignment came about, and whose opinion it was. All the attributes or properties assigned in such an action can also be seen as directly attached to the respective item or concept, possibly as a collection of contradictory values. All cases of properties in this model that are also described indirectly through an action, are characterized as "short cuts" of this action. This redundant modelling of two alternative views is preferred because many implementations may have good reasons to model either the action or the short cut, and the relation between both alternatives can be captured by simple rules. 
This class serves as a hook to extend the model if necessary by any other assertion making about relations expressed in the model.
In particular, the class describes the actions of people making propositions and statements during certain museum procedures, e.g. the person and date when a condition statement was made, an identifier was assigned, the museum object was measured, etc. Which kinds of such assignments and statements need to be documented explicitly in structures of a schema rather than free text, depends on if this information should be accessible by associative queries. If not, shortcuts may be used which refer directly the respective object with the assigned attribute.

 

P140 assigned attribute to (was attributed by)

Domain: E13 Attribute Assignment
Range: E1 CRM Entity
Quantification: many to many (0,n:0,n)
Superproperty of: E14 Condition Assessment. P34 concerned (was assessed by): E18 Physical Stuff
E15 Identifier Assignment. P36 registered (was registered by): E19 Physical Object
E16. Measurement Event. P39 measured (was measured by): E70 Stuff
Scope note: This property indicates the item to which an attribute or relation is assigned.
Examples: February 1997 Current Ownership Assessment of Martin Doerr�s silver cup (E13) assigned attribute to Martin Doerr�s silver cup (E19).
01 June 1997 Identifier Assignment of the silver cup donated by Martin Doerr (E15) registered silver cup 232 (E19).

 

P141 assigned (was assigned by)

Domain: E13 Attribute Assignment
Range: E1 CRM Entity
Quantification: many to many (0,n:0,n)
Superproperty of: E14 Condition Assessment. P35 has identified (identified by): E3 Condition State
E15 Identifier Assignment. P37 assigned (was assigned by): E42 Object Identifier
E15 Identifier Assignment. P38 deassigned (was deassigned by): E42 Object Identifier
E16. Measurement Event. P40 observed dimension (was observed in): E54 Dimension
Scope note: This property indicates the attribute that was assigned or the item that was related to the item denoted by a property P140 in an Attribute assignment action.
Examples: February 1997 Current Ownership Assessment of Martin Doerr's silver cup (E13) assigned Martin Doerr (E21).
01 June 1997 Identifier Assignment of the silver cup donated by Martin Doerr (E15) assigned object identifier 232

 

Outcome: 

E13 Attribute Assignment

Subclass of: E7 Activity
Superclass of: E14 Condition Assessment
E15 Identifier Assignment
E16 Measurement Event
E17 Type Assignment
