> I'm not sure that I agree with the idea of having a value for property X > *at each instant*... Hum, is it a question of time vs interval? If yes, then I agree, the notion of point is probably an overkill, but you might have intervals that are extremely short in duration ... In the media fragments WG, we cannot address a single time point, but it will always be an interval, of potentially of one frame duration. > Back to your copyright example: for me, the copyright is on a whole > media entity, spanning from T to T', even if embeded in a bigger one.

The analogy of words in a book vs a time point of a temporal resource is tricky! I'm not sure the words are the right unit to consider in a book, and I'm pretty sure you don't want to discrete a temporal resource.
