Changes in the H5MD file format ------------------------------- ### Changes in H5MD 1.1 1. The development process for H5MD is based on proposals Proposals are motivated and present a change to the file format in detail. A change should be accompanied by sample code to test the viability of an idea. This change is formalised in proposal 1. 2. Proposal 100: Storage of time information Several changes are made: The `time` dataset can be left out if it is not needed. The `step` and `time` datasets can be scalar, in which case the data is mandatorily sampled at equal time intervals. 3. Proposal 101: Particles and tuples lists A storage layout is defined for lists of particles and lists of tuples of particles. 4. Proposal 102: Storage of charges Charges can be stored in a `particles` group along other per-particle data. 5. proposal 103: Connectivity group The storage layout defined in proposal 101 is used to unify the storage of connectivity information, i.e. lists of pairs (or bonds), etc.
