Subject: RE: [regrep] Final draft recommendations for CC's and Registry - UML/UMM Profile for CCTS


Not sure that guarantees consistency.  If you don't harmonize the UML
models, the MOFs will always be different.  You have got to do the
difficult harmonization - using core components at the data analysis
level - to standardize the UML models.  Even then, as I understand it,
the optionality of XMI features in XMI 2.0 does not guarantee consistent
XML.  You must still have a set of parameters (NDRs ala UBL or CEFACT
ATG) for how to invoke the XMI. CEFACT ATG already has an approved
project for UML to XML and will be accelerating that work as soon as the
CEFACT NDRs are finished next week.
