[EMF Store] External Editor [message #1067372]

Hi there,

is it possible to use the EMF-Store (like git or svn) in connection with an external (non-EMF) model editor?
The model itself can be loaded as emf resource.

I'm asking because it seems that the changes to a model are only tracked by a linked editor (e.g. an ecp instance) as a history of operations which were applied to the model.

Thanks,
Marcel

Hi,
that is absolutly possible, the only precondition is that changes on the
model are applied using the API of the model ant not directly to a
underyling XMI file. If your editro works like that (like the generated
editro or ECP), then EMFStore is able to track the changes.
I hope that answers your question?

Regards

Jonas

Yep, that was informative.
Just a further question to the history/tracking: Are the changes tracked as operations?
Or is there some delta-algorithm implemented?

Yes, changes are tracked as operations, that is they are recorded WHILE
the model is changed. This opposed to diffing with a delta-algorithm
AFTER the model was changed. A more detailed description can be found here:
