Subject: [ubl-ndrsc] SQUIRTS, CCTS feedback and "Primitive Types"

There was an error
in the metamodel presented in our CCTS 1.8 feedback (v 5.2). At the end of
section 2 on page 7 we show BCC related to Primitive Type through
BCCProperty. That was wrong because it fails to distinguish the 1-1
relationship between a BCC and it's "content component". A better model is
shown here (inline and attached as PDF):
In this model we
explicitly show the distinguished relationship between BCC and its content
component (of meta-class "Primitive Type"). The association role
"contentComponent" captures this special relationship explicitly.
This model retains the BCCProperty to relate the BCC to its supplementary
components -- each of which needs to be named in relation to the
BCC.
Arofan -- do I
understand SQUIRTS right, that a SQUIRT is essentially what I've shown as a
"PrimitiveType" in the diagram.
So that's two
issues:
1. we added an
association directly from BCC to PrimitiveType for the content
component
2. we might need to
change the metaclass PrimitiveType to SQUIRT
Thoughts?
