The XMI (proposed) spec is on the OMG server ad/98-07-01 (base spec, DTD production rules, design guidelines) and ad/98-07-03 (DTDs for UML and MOF for exchanging models and metamodels respectively) . A preliminary spec' was presented in June.
The key points to note are as follows :
Some of these standards may be applicable to the XML repository efforts as identified below. (eg: UML/XML work is specifically identified below)
This co-operation across standards group is a good sign.
|If you download the OMG MOF document it is hard to unravel. The specific sections you should focus on are "1.1 Four Layer Metamodel Architecture", then "1.2 Organization of the MOF", and then "1.3 How the MOF Model is Described". 1.3 especially details in subheadings each of the properties of the MOF Model. These look to potentially have close equivalents in the XML Glossary for XML/EDI.|
