[CDO] Idiomatic way to install dynamic MM (i.e. Ecore file) [message #1856490]

We have a dynamic application and are unlikely to ever generate Java bindings for our metamodels. Instead, we would like to use the functionality of the server to upload existing schemata. I have seen the feature in the UI that performs this step by uploading an ecore file resource.

I am wondering what the idiomatic programmatic way would be to transfer an ePackage as ecore or other notation to the server.

I am further interested how I can list and access these packages programmatically and remotely.

Is there any documentation? Are there any tests for this case?

Hi Jörn,

There are several test cases that demonstrate how to use dynamic packages. You can find them by searching for

.ecore"

The most obvious one is org.eclipse.emf.cdo.tests.DymamicEcoreTest:

      CDOSession session = openSession();
      session.getPackageRegistry().putEPackage(ecore);
      CDOTransaction transaction = session.openTransaction();
