After a brief scan of Microsoft's site on OIM and the associated XML
Interchange Format (XIF), I'm concerned and confused about the conflicts
with the OMG's XML Metadata Interchange (XMI) specification.  XMI is in it's
second draft as a standard, and most of the large UML tools vendors have
voiced support (IBM, Platinum, Rational and Oracle are co-authors).

It appears that OIM and XIF are more focused on database and data warehouse
integration, but they also claim full UML metamodel support.  Currently, I'm
focused on OMG's XMI as the likely standard for UML model interchange.
However, I'm very interested on other opinions.
