Separate visual information from model when saving [message #213736]

Hello dear community!

We intend to implement a graphical editor for a uml2-like visual language,
so the model of the uml2-plugin fits covers our needs.

Till now our editor models contained specific visual information like
locations, colors etc. I wonder how to make this information persistent if
we used the uml2-plugin which does not contain (at least I didn't find it)
such information. I'm sure that we could extract this manually while saving
the model to a file and creating an extra file for visual information only
which would be merged with the model on loading.

But as this seems to be a common issue to me, I'd like to know if anybody of
you knows about a plugin that handles its models in a way that we could use
for our project. Thanks a lot!

Regards,
Tony

Hi Tony,
I currently work on a similar project as yours but it is still in very early
implementation stage. In my design considerations I think of wrapping the
UML2 model by using composition. More specifically, I have a wrapper class
for each Classifier within the UML2 that add the style and decoration
properties for the view side. It seems a flexible approach for me. You may
throw a look on my project's page at http://vuml.sf.net. There are detailed
analysis and design docs in UML, although my design has not completed yet.

Ferad Zyulkyarov

Take a look at the GMF project. www.eclipse.org/gmf

It defines a notation meta-model in EMF that persists the diagram
information separately from the user domain model. The notation model then
references the domain model.

I threw a look on GMF, it appears to be really very powerful. I will
consider how to get advantage of it.
