Hello,
is EMFStore capable of dealing with cross references? This is a very important feature since we are working pretty frequently with this feature of EMF: We want to check in models with cross references. When this models are checked out, the references should be resolved (for instance by checking out the dependend models or copying the dependend informations in the model).
I can't find any hint for cross references in the EMFStore Navigator or the reflective Editor. When I create a model the "classical EMF way" with cross references ("Load Resource...") and then click on "Add to EMF Client Platform", a new project is created in the Navigator with a little icon showing that this project contains cross references, but when I check in the project und later check it out, the references are lost and consequently the information as well.
Is the EMFStore-Client able to deal with cross references? What about the API? Is there any information or documentation available?
I'm looking for any response.
Best Regards
Philipp

Hi Philipp,
with the current trunk version of EMFStore this is possible and has been
tested. It is probably also possible with the current EMFStore release,
although I have not tested it.
A project can have links to resources (EObjects) outside of the
Project (Cross-project links and even links to other resources such as
external files or databases). This means not all referenced and/or
referencing models have to be in the same project.
Also there is no UI support for this so far, so links to external
resources can not be added via the reflective UI, that ships with
EMFStore. We are planning on providing I support for this in the
upcoming months.
More comments inline.
Cheers,
Maximilian

EMFStore will ignore references to external resource and will not track
changes to them, but it will keep these references even if they cannot
be resolved (e.g. on the server).

Where did you find this functionality, did you get this from the
democamo? I think, it was not intended to be able to handle cross
references and will probably not work as expected. To import a model
with cross-references you would need to implement a custom UI. The
import code itself would be simple. Just add the root element(s) to the
selected project (project.getModelelements().add(x)).

There is JavaDoc for all public methods. A good starting point is to
look at the example client here to discover the API:

Hope this helps, do not hesitate to ask if you run into problems!
