I think two levels (i.e. [criteria]<>[data]) is too simplistic. I would like to see a three level approach:
[criteria]<>[representation]<>[actual data]

I'm not really seeing this (yet). They way you put it, isn't the
representation implicit in the type of data that's being linked? As in,
if the [actual data] is X3D we're dealing with a "visual" representation
(of the subtype "3D model") and if it's an OGG container with a Vorbis
stream inside it's an "aural" representation, etc.

I may be using some terms that are not really suitable above. Let's take a concrete example to illustrate:

- Company A has a sign with their logo on outside their stores
- When this logo is detected the company wants a spinning sphere with the logo on to be displayed while a music piece is playing
- If you select/activate/click this spinning sphere the latest ad is played back as a video

Criteria: if computer vision detection of the logo occurs (criteria expressed in suitable markup language)
Representation: a spinning sphere + music (layout and resources of this representation expressed in suitable markup language)
Actual data: the video ad (content in specific format stored reached through some URI and over suitable protocol)

If we then consider that one device is a audio only device and one device is a touch display mobile then representation and actual data may change but criteria is the same. I was just thinking about the separation of these three parts. Maybe what I call representation is what other people call data? Note that both representation and data may need "layout" markup to explain how it should appear in our real world.

Best regards,
