[h5md-user] parameters group

[Felix Höfling]

Let me continue this discussion in a new thread.

There was the suggestion, to store box size and particle numbers as  
datasets in the /observables group, which I support. What about space  
dimension? Of course, it could be extracted from the dataset extents in  
observables/box. But this appears cumbersome to me. Why not storing it  
explicitly as attribute in the parameters group?

/parameters
 +-- dimension (or space_dimension)
