Leonard, if you keep saying that [lack of deformable skin animation] I 
must report you for abuse of the HAnim and X3D standards.

Specifically, HAnim and X3D include two tools for deformable skin 
(mesh) animation: the skeleton-skin hookups where the controllers are 
Joint rotations, and the Displacer where the controller is a numerical 
weight input. And they can work together.

If you are not convinced that X3D does deformable skin animation using 
the same types of documentatation as every basic skeletal animation 
tool uses, then you have not even studied the problem or the standard, 
or even any examples.

What did Dr Cerf wish to do abour that? Why is that true for you for 
X3D? How is the X3D format not durable? Depends upon the storage 
medium since X3D is juman readable. True, other archival formats are 
not so readable so are they are in more danger than X3D?
If you want want just a bunch of data sets with some validation and 
without much of a runtime, then look at collada.
X3D will always be able to use data from collada.

Sorry, what is the proposal? Do you wish to split the data and the 
names of data?
X3D is an archival format, it just happens to also have a high 
performance runtime.
That should not be a penalty or reason to somehow create two different 
versions.

Smithsonian? Google drive? Usually, he would't talk unless he had some 
sort of plan in mind.

If you are interested in the idea that X3D should accept many 
different forms of data, then look over Don's shoulder as he is 
working on implementation of a plan to convert and use typical mocap 
data.

Good Luck,
Joe
