<DIV><FONT face=Arial size=2><SPAN class=011274913-20102004>Has anyone done any
work on a MOF 2 model of EXPRESS? The OMG Ontology Definition
Metamodel (ODM) project is underway for MOF 2 models and future QVT
mappings for ontology languages that includes UML, OWL, E-R, logic, Topic Maps,
etc but not EXPRESS. I asked, and the OMG ODM team does not have the capacity to
include EXPRESS in their current project. I mentioned this in a few meetings in
Seattle. </SPAN></FONT></DIV>

has offered to have a discussion on this topic at the OMG meeting in a
couple of weeks in DC.</SPAN></FONT></DIV>

<DIV><FONT face=Arial size=2><SPAN class=011274913-20102004>It might make sense
for SC4 to get started in this area sooner rather than later. Our original plan
was to do a UML 1.5 Profile of EXPRESS as Part 25 E2, which we started in
Seattle, and then do a MOF 2 of EXPRESS once UML 2/MOF 2 were formally published
(starting late 2004 or early 2005). That would be Part 25 E3 or a Part 1x series
maybe.</SPAN></FONT></DIV>
