It is a representation of a resource in the sense that it was created/loaded from the resource. The arguments are passed to the loader to modify its behavior. An example for such an argument is "AsTemplate", which loads the resource as a template for a new document. (see MediaDescriptor for further details)

Models can be controlled by controller components, which are usually views of the model. (see Controller for further details)
