Re: XMI import

Hi Phil,
I have replied to your e-mail several days ago on [email protected] 
mailing list. Here is the text I am copy-pasting from that e-mail:
Hi Phil,
yes, MDR is able to load XMI 1.1 files, etc. But only if it has the 
metamodel that the XMI file conforms to. XMI file format is different 
for MOF models, than for UML models for example. Because XMI is a 
generic specification of how to derive XML serialization rules from a 
given metamodel. By default, MDR contains the metamodel of MOF loaded in 
itself (because MDR is implementation of MOF). What you are trying to do 
is to load a UML XMI into it. That does not work. You first need to load 
the definition of UML (from http://mdr.netbeans.org/metamodels.html - 
make sure you load the right version of UML and please read the 
instructions at the top of the page - besides the metamodel you will 
need the diff file that is also provided on the page). To do this, 
instantiate Model package in MDR Explorer (this will create a new 
instance of MOF extent - "database" for storing MOF metadata) and import 
the UML metamodel into this new extent. After that, you should see 
several UML packages under that new extent. One of them is named UML. 
Instantiate that package - this will create instance of UML metamodel - 
an UML extent, into which you should now be able to load UML XMI files.
Hopefuly this helps,
Martin
