RE: [plcs-dex] Traceability.

I agree the requirement but am not clear quite what you mean by usage.
Do you mean "where used", in the sense that engine serial number 3 has
been fitted to aircraft 4, 7 and 9?  The term usage also applies to
"hours run" or "number of starts".
Maybe iii) should read -- "have history of where used recorded".

There is a (potential-user) requirement to identify a part as

	i)   being serialisable
	ii)  being tracked/traced throughout its life
	iii) having it usage recorded

I would expect the need to serial number a part to be a classification
applied to a product or product version. Does such a classification
appear in a capability or DEX? if so which one? if not, which one should
I raise an issue against?

The need to track/trace a part may be part of the definition of the part
or may be a consequence of a user requirement. Where will this be
documented?

I would guess that the need to record usage will be a classification
against product or product version, as for serialization - same
questions.

In terms of a classification hierarchy, I guess that we have root class
"Traceability" and three subclasses
	Serialised
	Track/trace
	Usage

with usage implying track/trace and track/trace implying serialized/

Comments soonest, as I have a request for an example of what this would
look like, as this is currently done using properties (as an extension
to the PDM schema).
