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? -Bill Attachment: Visio-Lonely Metamodel 5-2-1.pdf Description: Binary data
