Using another data source for semantic model than xml-file [message #109668]

I have a question about changing the data source of the EMF model:

I want to use a remote data source in form of a proprietary repository.
Instead of the EMF xmi-file I want to connect to a remote repository, a
procedure my semantic model is able to. I want to implement the load
process only as the semantic model reacts on changes of the repository
already and vice versa.

What is the typical way to achive this? The size and possibilities of
the framework are overhelming me once again :-)

Is it simply implementing my own DocumentProvider oder do I have to look
more closely at the Resource-Framework of EMF?

Greetings,
Alexander

Alexander,

You'll want to implement a derived ResourceImpl and override doLoad and
doSave.
