Once the Registry instance is in place (embedded registry or remote registry), navigation is straightforward. It is the same as working with the Registry API. If we have a resource called "/foo/c1" in the Registry, you can access it using the Registry instance as given below:
Resource resource = registry.get("/foo/c1");
The resource object will represent the actual resource object in the Registry. But if the resource is a collection, then the object will represent the collection.
Tip
Once we have a registry instance, we do not need to pass a complete URL for all invocations. It is adequate to pass only a relative path to a resource.
