Tim and all others,
As I se it, the main purpose of the Concept Model is to define the terms we use to express different concepts among out selves and to a future external audience.
It first came from the need to clarify the difference between a DEX Specification and a DEX file because the term 'DEX' was used for both! The use of 'Business Concept' was also unclear...
I think it will help us all lot in the future if we complete and agree on this model, and then add new terms/concepts to it as we make them up.
