Description Fabian Steeg

2009-05-21 17:51:41 EDT

This is related to bug 277380.

To provide core Graphviz import for Zest I plan to use Xpand to generate basic Zest code from DOT meta model instances (based on the existing Xtext DOT grammar and parser from the org.openarchitectureware.graphviz bundle).

See http://wiki.eclipse.org/Graphviz_DOT_as_a_DSL_for_Zest for details about the planned implementation and examples of the desired result.

Implemented by attachment 137800 [details].

Something the team will need to consider:

The source code for openArchitectureWare contains references to both the GNU General Public License 2.0 (GPL) and to the Apache License 2.0. These two licenses include some contradictory restrictions. 

At a high level, EPL and GPL licensed code cannot mix at Eclipse, so more investigation is required here.

Thanks for pointing that out. I was not aware openArchitectureWare is not purely EPL licensed. In the long run, we should probably find a solution based on the new Xtext and Xpand from TMF and M2T anyway. 

This would also require an updated version of the org.openarchitectureware.graphviz bundle, which in the meantime has been moved out of the core openArchitectureWare into a project of its own (http://code.google.com/p/emfmodelvisualizer/).

Anthony,

Where did you see the GPL (and Apache stuff).  I looked at the one bundle that Fabian is dependent on, and that bundle was marked EPL.

From my understanding the problem was the dependency on the rest of oAW 4.3. The latest milestone (attachment 144365 [details]) no longer depends on oAW 4.3 and uses the 'org.openarchitectureware.vis.graphviz' bundle from http://emfmodelvisualizer.googlecode.com/svn/galileo/ (which uses the Eclipse Modeling components from Galileo). See bug 277380, comment 7.

I just googled "openarchitectureware license"

and found https://www.ohloh.net/p/3702/factoids/1473445 , I do not know it's accuracy

There are no non-eclipse.org dependencies anymore for the import functionality.

See DotImportSuite for related tests and setup at http://wiki.eclipse.org/Zest
