Dear All,

Here the old scope note:


      E13 Attribute Assignment

Subclass of: E7 <#_E7_Activity> Activity

Superclass of: E14 <#_E14_Condition_Assessment> Condition Assessment

E15 <#_E15_Identifier_Assignment> Identifier Assignment

E16 <#_E16_Measurement> Measurement

E17 <#_E17_Type_Assignment> 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 allows 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 characterised 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.

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 structured queries.

=====================================================================
Here my new proposed scope note:


      E13 Attribute Assignment

Subclass of: E7 <#_E7_Activity> Activity

Superclass of: E14 <#_E14_Condition_Assessment> Condition Assessment

E15 <#_E15_Identifier_Assignment> Identifier Assignment
<#_E16_Measurement>

E16 <#_E16_Measurement> Measurement

E17 <#_E17_Type_Assignment> 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. The type of the property asserted to hold between two 
items or concepts can be described by the property /P2 has type/.

  This class allows for the documentation of how the respective 
assignment came about, and whose opinion it was. Note that all instances 
of properties described in a knowledge base are the opinion of someone. 
Per default, they are the opinion of the team maintaining the knowledge 
base. This fact must not individually be registered for all  instances 
of properties provided by the maintaining team, because it would result 
in an endless recursion of whose opinion was the description of an 
opinion. Therefore the use of E13 Attribute Assignment marks the fact, 
that the maintaining team is in general neutral to the validity of the 
respective assertion, but registers another ones opinion and how it came 
about.

All properties assigned in such an action can also be seen as directly 
relating the respective pair of items or concepts. Multiple use of E13 
Attribute Assignment may possibly lead to a collection of contradictory 
values. All cases of properties in this model that are also described 
indirectly through a subclass of E13 Attribute Assignment are 
characterised as "short cuts" of a path via this subclass. This 
redundant modelling of two alternative views is preferred because many 
implementations may have good reasons to model either the action of 
assertion or the short cut, and the relation between both alternative 
can be captured by simple rules.

  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 structured queries.

Best,

Martin
