Dear Jeff,

the problem is the following. Imagine that I use RDF to describe
a resource such as an image. How to I model in RDF that I
want to refer to a fraction of this image. This might be needed
if want to express the following.

Subject (Susanne) - Predicate (is_the_person_in) - Object (rectangle  
in an image)

Looking at multimedia document models such as SMIL and other
research models they provide modelling constructs that virtually
select a part of a medium. In SMIL you can jump to a subsection
of a video, or add a link to a rectangular area in an image.

Annotations in the photo use case might need the same construct
to label an image region with a name. Such a selector, however,
is not part of RDF.

Kind regards,
