downloaded 3.2M4. But I still cannot run any example applications either in
the GMF plugin itself or follow the tutorial at its home page.

Everything happened shows that GMF is still under development and is not
able to be used very smoothly, its help in the eclipse help contents is also
not very mature. Maybe you guys have already run throught the tuturial. If
there is any experience, please share it.

I also generated the xpdl model from xpdl2.0 schema. A very interesting
thing is that, EMF does generated two model named xpdl1 and xpdl2. For now,
I haven't find their differences and the classes in each model do have some
wrong information. I know that the generation from xml schema to ecore is
not 100% correct. So this is what we should keep an eye on.

GMF is now M3. I am thinking that maybe this project fully depends on GMF's
schedule. Am I right? Do we have our own schedule now? I want to have a look
at it.

Why have you tried "experimental" versions? I have simply installed the
latest stable eclipse (3.1.1), added GEF though "Software Updates" ...

.... and have experienced no problems. To get started, there is a
complete Redbook from IBM with step by step instructions. It has been
written for an older GEF version, but is still very useful. There are
also several open source projects around that build on GEF and can help
to get started.

EMF generation for XPDL 2.0 is an advanced topic. It does work, but is
too complicated to describe in a few sentences. I had the advantage of
trying it with XPDL 1.0 first and really understood EMF generation while
doing this.

The XPDL 2.0 XSD schema also uses the XPDL 1.0 namespace to achieve
backward compatibility. That's why you get two models.

Though eclipse/EMF suggests that everything is just point and click, it
really needs deep understanding (first of all of the schema itself). I
have spend about two weeks' evenings before I succeeded with the
generation (starting with zero EMF knowledge). But I do believe that it
is a good investment of time on the long run.

Of course, there are other graphical toolkits around ...

Hi, Michael:

I used "experimental" versions because they are on the GMF 1.0M3's
requirements list. I have some experience on GEF and are trying to get
familiar with EMF. But talking about GMF, I have no experience at all. So I
read the tutorial and run the example(which failed).

About EMF generation for XPDL 2.0, I am thinking whether we should draw the
UML from XPDL first, and then make the generation from UML. This can
guarantee the correctness. After all, we must understand the XPDL schema
first after which drawing UML should not be that difficult.

Again Michael, if you have already run the GMF tutorial's example
successfully, please tell me how to make it.
Thank you~

I downloaded Eclipse 3.2M3 (windows platform) and GMF 1.0M3 as well as
all other dependencies and it seems to work well except the taipan demo
- that is, at least running all other samples works.

Here is the full list of dependencies needed:
http://download.eclipse.org/technology/gmf/downloads/drops/S -1.0M3-200511182000/index.php

Hope this helps.

along the tutorial you will find yourself stuck when you want to create a
new gmfgraph. The only way to be able to create this is to get the GMF
integration build. Even though you get this, you'll still be stuck as the
gmfmap editor seems unstable : I can't get the canvas mapping work...

Did you successfully do all the tutorial ?

No I actually did not, I only looked at the few provided demos.
I guess this raises the issue if GMF is the correct framework to base
our work on, or if we'll have to stick with EMF/GEF. Altough according
to their roadmap they will have an API freeze for 1.0 in march, so we
could expect things to be more stable by then.

Roman

This is also my opinion. At this time I would say we cannot go with GMF,
at least until it becomes stable.
However, reading the tutorial, GMF seems interesting to speed up
development. I'm always afraid of using code generation tool, especially
when the times come to generate again. But things seems pretty well
separated using JET. I'm reading EMF/GEF/GMF material but if anyone has
some concrete user experience on using GMF it would be interesting to
know what are his thoughts.

I think that we can keep an eye on the project and mention that this is
a possible way to implement things for the creation review.

I would agree with Allen. He is original (in that he is not mimicking
opinions and visions of others, in this case, of IBM).

I have exactly the same project for me alone for 3 months that you all are
going to accomplish in more than a year scale.

I should recreate anew in GEF with EMF already existing Workflow Graphical
Editor in Swing.

What is killing me is that no old/Swing code may be (re)used and
requirement of EMF. It is just "pain in the ass". Nobody has experience with
it but everybody wants it.

I also had big enthusiasm about EMF initially . It is a great time-,
good-wishes- and sanity-killer.

Let me cite from
http://en.wikipedia.org/wiki/Model_view_controller
:
"The best models are fully encapsulated, meaning that they implement every
aspect of that real world object of interest to the domain of interest, and
that they don't have any extra code that doesn't model the real world."
what I am rereading for a second day for some or another reasons.

Correct me,

Eclipse 3.2 is on its way and I think we should go with it.

I had a similar experience but as of the following nightly build,
http://download.eclipse.org/technology/gmf/downloads/drops/N -N20060104-200601040410/index.php ,
everything is working fine for me.

We are going ahead with the generation of a GMF based front end for a DOD
communications model defined with EMF.
I will share our experiences and follow your development efforts as they may
be of use to us for our OV-5 activity models.

OK I'm going to give it a try. Thanks for this pointer.

This is interesting. Very few people have experience on GMF based model
and I think that there are few people that have built a EMF-backed GEF
application either.
Thanks to keep us posted about your experience.
