Paul,

Thanks for the refs, particularly the unisys URL.  I've attached an
email I received from the x3l8 group back in Dec.  Now, the question I
have is: Has Microsoft really jumped onto the XMI bandwagon, or is the
collaboration the gateway that is described in the unisys article that
you cite?  In other words, is Microsoft dropping the XIF in favor of
the XMI?

Subject: FW: UREP-GENERAL: Microsoft jumps on the XMI bandwagon]] Date: Wed, 30 Dec 98 08:47:08 -0500 From: [log in to unmask] To: [log in to unmask], [log in to unmask],      [log in to unmask] ('Stephanie Haas'), [log in to unmask] (Powers_R),      [log in to unmask], [log in to unmask], [log in to unmask],      [log in to unmask] ([log in to unmask]) I think MS (Microsoft) joining MDC (Metadata Coalition) is a significant development. To understand MS's repository and Open Information Model, see Information Modeling Using the Microsoft Repository, Phil Bernstein, Repository Architect (Microsoft) March 26, 1996 PowerPoint slides at: http://msdn.microsoft.com/Repository/techmat/whitepapers/DamaOver/index.htm You can get to a lot of other MS Repository related info from the left panel. To see how the MS Repository is the key to the Datawarehousing Framework, see & hear Bill Baker's excellent lecture (PowerPoint with voice) at http://www.microsoft.com/Seminar/1033/SQL7DataWarehouse/Portal.htm Other interesting lectures, particularly, on SQL Server 7, are at this site:  <<Microsoft SeminarOnline.url>> > -----Original Message----- > From: Burton G.
