[JIRA] Created: (CAY-762) ERDiagram for Object Entities in Cayenne
Modeler
ERDiagram for Object Entities in Cayenne Modeler
------------------------------------------------
Key: CAY-762
URL: https://issues.apache.org/cayenne/browse/CAY-762
Project: Cayenne
Issue Type: New Feature
Components: CayenneModeler GUI
Affects Versions: 3.0
Reporter: Ahmed Mohombe
Assigned To: Andrus Adamchik
Please add an ER Diagram to the Cayenne Modeler. This is the feature that I miss the most from WebObjects.
For start it would be even enough to have an ER Diagram View (so no interactive activities) - just display and layout of entities.
I think this would help allot and would increase the productivity with CM - most people think visually.
I don't think that it would be complicated to implement, the most complicated question to answer is what graph library is allowed to use, due to the restrictive "license compatibility" of the Apache license.
Thanks in advance,
Ahmed.

This takes us back to the Modeler plugins discussion. If we have a
plugin environment in place, third party plugins will not have any
licensing restrictions (kind of like Maven, hehe)

We'll have to do a "complicated license talk" with the ASF no matter
what happens unless the published license of the code appears in the
list of approved ASF licenses.
And anything that does not fall under "Category A: Authorized
Licenses" will be difficult to integrate.

GPL falls under "Category X: Excluded Licenses"

+1 - I think this would be an awesome addition.

I asked Francisco if he would mind if I redistribute parts of his code
under the GPLv2. This was no problem for him. I'd first contact Francisco
before doing some complicated licence talk with the ASF.
But first of all it would be required that everybody is OK with adding
some (this) diagram editor to Cayenne. My earlier mail was just a
suggestion. Please first have a look at alternatives and at the
source/implementation in question...

The license appears to be the Open Software License despite the
commentary at the top of the page. We'd have to run this license by
legal-discuss before we could use it as it has not yet been classified
by the ASF yet.

I had the same problem and therefor was contacting Francisco Morero the
author of the jdbcmanager tool. He has written some Diagram viewer for his
tool and I asked him for permission to use his sourcecode. I chose his
source because it did not require any third party libraries but was
working with the normal Swing distribution.
The integration was a question of a few hours. Perhaps that would be a
solution for Cayenne as well. Afaik there was some traffic on one of the
Cayenne lists a few years ago concerning this.

Adrian
