[h5md-user] proposal 101 - update

[Pierre de Buyl]

Hi all,

Felix suggests in
http://nongnu.org/h5md/proposals/0101_particles_and_tuples_lists.html

"""Alternatively, let `particles_group` point to the respective group in
`/particles` using a hard/soft link, which ensures that this group exists."""

It cannot be a hard link because if the list is time-independent you cannot have
this hard link anywhere (hard links go into groups).

However, if we have

<list_name>: Integer[N]
  +-- particles_group: HDF5 Reference

(see http://www.hdfgroup.org/HDF5/doc/RM/RM_H5R.html)

References can be stored as attributes. I vaguely remember that we discussed the
use of references in the past but cannot find this topic on the list.

Has anyone a comment on the use of HDF5 references?

Cheers,

Pierre
