Re: [emf-dev] Does EMF support JOIN of several models?

Ivy,

Please ask questions on the newsgroup
rather than on the mailing list.  

If "joining" two models requires
creating a new model with classes that derive from base classes in both
models, then the data will need to be migrated, since the data will be
typed according to the base classes and not to the derived classes.  If
"joining" two models simply requires a third model with new classes
that reference instances of the two existing models, then the new instances
can just be created to refer to the existing data.  Either way, there's
nothing automated to make this happen, although there are interesting transformation
tools that may help you map instances of one model to instances of another;
links for then are on the EMF Corner page.

Subject	[emf-dev] Does EMF support JOIN of several models?

Hi all,
 
I have a question regarding the JOIN of several models
within EMF. 
 
For example, one user created two separate models, and
EMF generated the APIs for these two models, and then this user input a
great deal of data into the models. But later on, he found that he needed
to join these two models into one big model. But he didn't want to lose
any data or his own codes. 
 
Could EMF support this? If yes, how does EMF achieve this
goal? And what should this user do?
 
If anybody knows the answer, please give some detailed
explanation. 
 
Thanks a lot!!   _______________________________________________
