Hi Pierre,
I wrote a proposal for the storage of quaternions http://nongnu.org/h5md/proposals/0104_particles_quaternion.html Comments welcome.
"The specific meaning of the quaternion depends on the creator of the data."
If the interpretation is undefined, why put this into a standard? It looks more useful to define a standard method for adding program-specific data to a trajectory, and then use that method for adding quaternions or whatever else.
Konrad.
