[DDI-SRG] [MRT] Model cleanup: leaf classes without attributes and associations to other classes

[Gillman, Daniel - BLS]

Designation isn’t really needed since we have the signification pattern. As a result, each application of designation, whether it be a code, term, or other, will be modeled in the realization. Designation, being a generic term, probably is not needed.

I think that Dan was the one who advocated for Designation.

We are not using Designation anymore.

Thanks Jay.

Just to be sure that I understand correctly:

·         ControlStep, ScriptingAgent and RulesEngine can be removed.

·         Sequence, Service, and Designation should be maintained for the purpose of future expansion. Currently, nothing (like attributes and associations) will be added to them.

Is this correct?

I’ll ask Larry regarding Representations-Designation.

There are some leaf classes (i.e. they get not inherited further) without attributes and associations to other classes.
This kind of classes don’t seem to have practical value in their current definition. Either they need some attributes or associations or they should be removed.

Do you have any suggestions?

Many.

ControlStep, ScriptingAgent and RulesEngine should have been removed when I was cleaning up with Flavio.

Sequence and Service need to remain as is in line with idea that this is a conceptual/logical model that some but not all will use for implementation too (Smile).

Sequence is a container for other ControlConstructs and because it inherits from ControlLogic which is reflexive maybe Sequence can host other ControlLogic and itself.

Service is an idea we would like to finish at another time.

UnitSegmentLayout belongs to Larry.

Designation is another touchpoint with Signifier, Sign and Signified
