Information Model Support

I just received a private email with a suggestion to improve the SAE metamodel.

"I am approaching information management from the Information Engineering perspective. I am suggesting that the metamodel indicate the different users views or levels of data oriented models (Mission, Subject Area, Conceptual Logical and Design). These models serve different purposes in the Enterprise Architecture stack."

It's an interesting idea, and we shall consider it. However, we are conscious of the need not to overload the metamodel, so it may get excluded on those grounds. We are also keen to keep the metamodel as uncontroversial as possible. I am sure there will always be room for people (including ourselves) to differentiate themselves by adding local refinements.
