SACM11 — Properties of Model Elements must be Distinguished from Properties of what they Represent

Obviously, properties that apply to Model Elements must be distinguishable from Properties of what they represent. Both these kinds of properties appear in SACM models. The issues titled “Property Inherence Hierarchy” states a way of doing this.

Deferred as still valid for SACM

RTF agree that the standard needs to make a sharper distinction between ‘uncontestable’ properties and assertions made (e.g. about evidence). In addition, there needs to be a clear distinction between properties of model elements and properties (assertions) concerning domain objects being represented. All assertions should inherit off a based Assertion class. To achieve this in SACM 1.1 would require a major reorganization of the standard that would significantly break backwards compatibility.
