Just a thought. The metamodel presuppose the hard conceptual work done by the thinker in grappling with a domain, and is best kept to oneself.
A friend told me once that when I presented my models to groups, that I showed too much scaffolding and should just show the end produce thanks to CW for that advice….. I showed them too much of how the magic was done, but I should have just done the trick.
This is SOOO true, and I am realising now that really, as an architect, this is your private investment.,
I will spend more time firming this up, but wrap it up at the same time.
