But at the same time making the general assertion that the resource is a
as:Link.

<http://example.org/image.jpg> a as:Link, dctypes:Image;
  dc:format "image/jpeg" .

be bleeding semantics out into the web at large, when it should be kept
within the AS space.

-1 on removing the functionality, +1 on exploring how else it might be
represented
