[news.eclipse.modeling.mdt.uml2] Re: Strategy for loading commercial UML

["James Bruck" <jbruck@xxxxxxxxxx>]

Hi Dawid,

There is an ongoing effort at the OMG to get XMI interchange working between 
various tools.
Have a look at:
http://www.omgwiki.org/model-interchange/doku.php?id=start

There is also a XMI validator that you can use to verify XMI:
http://syseng.nist.gov/se-interop/sysml/validator

Cheers,
- James.
