Package Registry at Development Time [message #656323]

Hi,
I don't know whether this question has been asked before or not, but i am not sure whether the packages in an Ecore model can accessed in the development time. To ellaborate my problem, Assume that i have an Ecore Model "library.ecore" and it has "library" package in it, whose nsURI is "http://eclipse.org/modeling/emf/librarytest/1.0.0". I have also exposed the package through the "org.eclipse.emf.ecore.generated_package" extension in plugin.xml and have given the same nsURI used above as the URI.
Now if i have some xml files also in the development time:-

<?xml version="1.0" encoding="ASCII"?>
<library:Library xmi:version="2.0" xmlns:xmi="http://www.omg.org/XMI" xmlns:library="http://eclipse.org/modeling/emf/librarytest/1.0.0" location="Anshan">
  <books>
    <instanceOf href="../publisher/dpunkt.xmi#//@manuscripts.71"/>
  </books>
</library:Library>

And I have a search framework installed, which is going to search for data, based on the registered packages. But, I think that, my package would not have been registered, as i am still in development workbench. Is there a way by which i can use those packages which are there in the development time at development time itself?

I had seen at some places that we can use the platform:/resource:/<project-name>/<path-to-ecore> to refer to ecore, but i have to refer to the Package inside the Ecore and not just the Ecore. Any suggestions on how to do it??

You'd have to find them first. Once you do, you can register them in
the local package registry of the resource set your using to load your
instances. Or you could use an xsi:schemaLocation in the instance
document to point at the physical location of the Ecore resource. I.e.,
try doing Create Dynamic Instance... on the EClass at development time
and look at how the instance resource is formed.

Some other folks have worked on solutions to this problem (Olivier
Moïses) using the PDE to find all the registered models in the workspace.

I don't want to do it programmatically as i cannot alter the existing code. I would like to register the EPackage inside the Ecore registered either through Extension points or by some other means(directly through the IDE). Isn't there any way to do that?

Is there any link on this topic, so that i can get an idea about it?

Yes, but that sounds different from your original question. Where
exactly does the package you want used exist? I.e., in the running IDE
(where extension points apply) or in the workspace of the IDE (where
extension pointers don't apply)?

Sorry for the confusing reply, but my requirement is still the same. I have an ecore file which has a library package in it in my workspace(development time only). I want to refer to refer to the EPackage(in development time only), but i can't do it programmatically. So i need some other way, directly through the IDE. I guess it is not possible.
