I have a base structure for my model (ecore). The UI that uses this model allows users to configure properties for Persistence Data Stores. The Data Stores configurations themselves are pluggable and the configuration for each of these Data Stores is very specific to the Data Store.
[Attaching an image to show two such configurations]
Considering the UI is pluggable, I would like the model to be pluggable as well. The provider of the UI extensions would also provide model extensions and would know how to populate the model. Is there some way to achieve this?
I see EMF Facets (www.eclipse.org/modeling/emft/facet/) tries to address this problem, but it's in incubation. Are there any other creative ways someone achieved this?

This is normally done by encoding all this information in the URI
and specializing URIHandlers or by providing specialized resource
implementations.<br>

I don't know what "this" is. Is it similar to this:<small><br>

You can always model your objects so they can be annotated with
other objects, much as EModelElement can contain EAnnotations which
in turn can contain any other object or can reference any other
object.<br>
