| Re: [gmf-dev] Tiger GMF Transformation |
Hi GMF Team,I've attached a PDF file with an overview of model and wizard changes (mainly screen shots) of the GMFtrans extension, as discussed in the last developer call.
Please let me know if this is helpful and what further description do you need.
Best wishes, Karsten Richard Gronback wrote:
Hi Karsten, Thanks for the additional info. I've added this to our GMF Dev call agenda for tomorrow's call: http://wiki.eclipse.org/GMF_Dev_Calls It would be helpful if you could join and discuss in more detail. Thanks, Rich On 9/10/07 8:36 AM, "Karsten Ehrig" <karstene@xxxxxxxxxxxxxxx> wrote:Hi Richard, I've attached a PDF file describing an overview of the changes. Here are answers to your questions below: 1. No API changes required 2. GMFtrans uses JET (as in GMF2.0M3) while GMF2.0 uses XPand. There are only some changes in a few number of GMF templates. JET is also used by the Tiger EMF Transformer. 3. no 3rd part libraries involved (we would only consider the Tiger EMF Compiler for contribution). Best wishes, Karsten Richard Gronback wrote:Hi Karsten, Perhaps an overview of what was changed could be provided? Based on the PSF file you provide on the website, it seems both the tooling and runtime components of GMF have been altered. It's tough to consider any contribution without a clear understanding of the impact it represents to the current code base. Pulling modified GMF sources from your repository doesn't make it easy to determine. Patches are the typical "Eclipse way" of providing contributions of this nature. Some important questions we'd need answered are: 1. Are there API changes required for this contribution to be accepted? 2. Could the addition of Tiger functionality be accomplished using the current extensibility options (model extension/decoration, Xpand template overrides/aspects, etc.)? What changes could we make to allow for Tiger to be added in this manner? 3. Finally, just to be explicitly clear about 3rd party libraries used, nothing outside the EMF Transformer code also being considered for contribution is utilized?

Adapting the code to the released 2.0 stream requires lots of changes which we like to do only if you definitely consider a contribution. In this case we would be also glad to discuss a contribution of the related Tiger EMF Transformer code to EMF or EMFT. Best wishes, Karsten Richard Gronback wrote:Hi Karsten, And what is the progress on becoming part of GMT? We'd not likely introduce a dependency from GMF to a component in GMT; that is, outside of something we'd include in our "experimental" SDK. I'd be helpful to assess the impact of the changes you've made if a patch were attached to a bugzilla using the released 2.0 stream code base. Thanks, Rich On 8/31/07 4:37 PM, "Karsten Ehrig" <karstene@xxxxxxxxxxxxxxx> wrote:Hi Richard, in fact we already got an invitation from Jean Bezivin to join GMT with the Tiger EMF Transformation Project (short EMT). Maybe EMT could be also used in the GMF generator: "Like in EMF, the GMF Generator model can be automatically created from high-level models. Unlike in EMF, GMF significantly reorganizes the diagram description while creating Generator model. The transformation from high-level GMF models to Generator model is not one-to-one transformation like in EMF, so more powerful techniques are used here. Currently this transformation is hand coded in Java classes, while some model-to-model transformation techniques could be used there in the future."

I see it's all released under EPL, or are there additional libraries that have another license? Thanks, Rich On 8/20/07 10:50 AM, "Karsten Ehrig" <karstene@xxxxxxxxxxxxxxx> wrote:Hi Richard, great, that we are still involved. A user and developer documentation for our extension is now available at: http://tfs.cs.tu-berlin.de/emftrans/gmftrans/userdoc.pdf Moreover a ZIP bundle containing all projects and a project set file for source code installation from the CVS repositories is available at: http://tfs.cs.tu-berlin.de/emftrans/gmftrans/ Up to now, we do require Eclipse3.3M2 and GMF2.0M3. This is because the extension is mostly implemented as patch/extension for the described versions. Please let us know your opinion about the current version. Is there a chance to integrate the Tiger GMF Transformation in GMF 3.0? If you consider a contribution we are happy to help with adapting the code to the current GMF version.

The last time I tried, it was a rather involved configuration. Any chance some of the documents on the website are translated to English? ;) Thanks, Rich On 7/19/07 1:46 AM, "Karsten Ehrig" <karstene@xxxxxxxxxxxxxxx> wrote:Dear Team, hopefully you remember our group from the kick-off meeting where we promised to implement complex editor operation support in GMF.
