org.locationtech.udig.catalog.IGeoResource
Represents a handle to a spatial resource.
The resource is not guaranteed to exist, nor do we guarantee that we can connect with the resource. Some/All portions of this handle may be loaded as required. This resource handle may also be the result a metadata service query.
Implementing an IService

Implement the abstract methods and you are good to go:
- getInfo - information describing the resource such as name, bounds and CRS
- service - the service providing the resource
- getIdentifier - unique identifier used to track the service in the catalog
Please consider implementing support for resolve( ImageDescriptor.class, null ) as it will allow your IGeoResource to show up with a unique representation in the Catalog view.
