How to review diagrams in EA

[Espen Albrektsen]

Hi.

We need to produce a formal review of our EA model.
For classes and components, we are able to use the "Status" field to track if an item is approved or not.

But for diagrams, there is no status. I need

a) A method to know which diagrams have been reviewed
b) An "evidence" of the review - for example - can I link an EA Review to a specific version of a document
c) Prevent users from accidentally modifying diagrams _after_ they have been reviewed.

I ams ure more users have similar needs - what is the best way to solve this?
