Used to represent the HTTP-accessible realization of an information resource on the Web. The equivalent of irw:WebRepresentation, the Annotated Resource is that which generally triggers the act of tagging. Being dereferenceable by definition, it also provides the address that will be bookmarked on delicious-like sites and work like an anchor for tags. This said, the resource being tagged is in no way limited to HTTP-accessible data (indeed, what supports an act of tagging may very well be what the Web representation represents, a non-information resource for example, instead of the Web representation itself).
