I think that x3d is a very specific type of 3d data. In most cases, 3d 
does not include behaviour. That means that it is about geometry and, 
probably, some meta information. This may include structure such as 
layers as well as editing support. There are some open standards for CAD 
which are well documented, though support in CAD software is often 
underdeveloped. See e.g. STEP or IGES.

So the challenge for what we are usually talking about on this list is 
to include behaviour and scene logic - which touches the problem to 
archive software as implemented algorithms besides data. The same 
problem as faced by typical dynamic web-content. I remember the times 
that mirroring a web-site was perfectly possible by copying, and was 
used to archive web pages.

Cheers, Lars.
