EMF Compare - Diffing EMF UML2 XMI [message #86682]

Dear All,

We get sent business requirements etc as XMI files produced by a recent
version on Rational.

We need to be able to tell exactly what has changed when we get sent a
new XMI file vs the one we already have/are working from.

Looking at them, they appear to be the std EMF UML2 XMI.

Is there any tutorial or example as to how one would go about using the
EMF Compare tool to diff the 2 XMI files?

Dear All,

I'm also interested in available API and current state of Compare.
Latest build has dependencies on Eclipse 3.2.2 and EMF 2.2.2. Are there plans
to build Compare against Eclipse 3.3?
Also I can't find where sources hosted in Eclipse CVS.

Best Regards,
Sergey.

BTW with Eclipse 3.2.2 & the most recent update manager version I get
the following errors when I do a "compare as model" I get a
NullPointerException followed by a Unhandled event loop exception (see
below).

Is the latest version being built against eclipse 3.3. in preparation
for Europa?

Sergei,

Code source is available on CVS :

dev.eclipse.org:/cvsroot/modeling/org.eclipse.emf/org.eclips e.emf.compare/*

Cedric Brun is the lead for this project, I CCed him.

Hi,

Right now compare is being cleaned up, in the gui as in the comparison
engines and API. The lowest build dependencies are Eclipse 3.2.2 and EMF
2.2.2 but it should build on Eclipse 3.3 too.
The API is not frozen yet, more especially concerning the merge support.
I'll provide tutorials as soon as the API is considered as frozen.

Concerning the XMI file, if EMF is able to load them, then we should be able
to compare them, if not its a bug. Do not hesitate to report it. I would
recommend to use the latest integration build (which will be done today),
it will fix some bugs.

In the latest builds the usage is quite simple. when one click on "Compare
with each other" the emf comparison is launched if the file is a "Model"
content-type (you can configure that in the preferences). The "Compare as
models" action disapeared and emf compare may now be called using SVN/CVS
or the history view too.

cheers,

Cédric

Excellent

Which is the relevant update site?

http://download.eclipse.org/modeling/emft/updates/site-inter im.xml

?

Is the compare tool being aimed to get into the Europa release?
