RE: XMI reality check

["Kanaskie, Kurt A (Kurt)" <kkanaskie@lucent.com>]

Yes the alphaWorks technology. The work was last touched around 6/2000. The
biggest problem we had was the size of the XMI. The UML model was 40 Meg and
the resultant XMI was over 100 Meg. As you can imagine this was a stress
test for the parsers and XSLT.

Exchanging XMI with different tools, I didn't personally, but this was an
action item for others on the team. Mega said they would be able to but I
never heard back. Someone was to try with GDPro but I don't recall the
results. The OAG team had chosen Rational (they had to choose one) as their
development tool and left it up to other tools to import XMI or RoseMDL. 

As I recall XMI's stuff preserved the model graphics perfectly.

Kurt,

Thanks a lot.  I assume this was IBM's alphaworks XMI toolkit?
http://www.alphaworks.ibm.com/tech/xmitoolkit 

Did you try exchanging XMI models between different UML tools?

>IBM's toolkit was also better at preserving the model graphics when
imported.

Did that mean, preserving model graphics thru XMI was not very good
even with the IBM toolkit?

All,

I have had some experience with XMI (Unisys's plug in for Rational and IBM's
XMI toolkit). I agree XMI is ugly but it was intended for machine to machine
exchange of models, not human readability. I have found IBM's version to be
more complete that Unisys's for what I was trying to do. IBM's toolkit was
also better at preserving the model graphics when imported.

I successfully used XSLT on the XMI from a UML model, based on Booch's
meta-model for XML Schema, to generate a human readable XML DTD. This
approach is being finalized by OAG as their method of generating DTDs from a
UML model of all of their BODs (170+). Thus I believe that XMI can be used
to generate XML instances of business processes modeled in UML. However,
this approach will require some consistency changes to the UML version of
the Spec Schema.

Another benefit of XMI is to generate meta-model instance DTDs that can be
used to check model instance UML models. The stock tools to generate these
DTDs are also quite ugly and not human friendly, but serve the purpose. 

Regards,
