Issue 450: Update the scope note of E54

Starting Date: 
Working Group: 
Closing Date: 

In the 45th joint meeting of the CIDOC CRM SIG and SO/TC46/SC4/WG9; 38th FRBR – CIDOC CRM Harmonization meeting, and in  accordance with the decision reached on Issue 349 Belief Values, a new issue has been formed to update the scope note of E54 Dimension.

Changes must include removing of the phrase: An instance of E54 Dimension represents the true quantity, independent from its numerical approximation, e.g. in inches or in cm. A clause stating that error margins on dimensions may sometimes not be relevant can be added to the definition.

Current Proposal: 

Posted by Martin on 16/6/2020

Attached along overdue homework, changing the definition of E54 Dimension from the "true quantity" to the empirical one. I have also modified it to allow for dimensions being results of theoretical calculations and data evaluations. I used the term "following the laws of physics" to exclude models such as discrete time.


In the 47th joint meeting of the CIDOC CRM SIG and ISO/TC46/SC4/WG9; 40th FRBR - CIDOC CRM Harmonization meeting; the sig reviewed and accepted the proposed, by MD,changes of the  scope note of E54 Dimension. The final version can be found here. Also it is decided to open a new issue to rework on the examples of E54.

The issue closed
