Yes, I see both of them as data.  The "representation" is, presumably,
a 3d file set spinning and a wave file of some sort.
When I say [data] <> [criteria] I am enclosure of those formats.

The fact that that data can, in tern, act as a trigger to further data
(when the user clicks it) imho doesn't change the fact the original
information popping up is also itself data formats that have been
linked to the trigger. So to me your scenario is two separate
[data]<>[criteria] associations.

I think the difference here is the first (the automatic appearing of
the sphere+music), is a passive/auto triggered event, and the "user
selects" is a manual one.
You could just as easily have a video file as the "representation" in
this scenario, that then pops up a big 3d file for the "data". So I'm
not really seeing the separation myself.

I do think there is variably presentation issues, but I see this akin
to feeding device's different data based on their specifications. Akin
to the @media in css. So, as part of the criteria, we should also be
able to specify its intended for a certain device.
