RE: Methods in the NIM requirements



David, Thanks for this reply/email.

Let me try to reset the thinking on CIM and DEN.  If you look at CIM as
organizing, supplementing and pulling all the management info together,
similar to what the backing OO databases do for the enterprise console
vendors - then, you get a whole different view rather than saying that CIM
and DEN are recreating/redefining the world.
