Hi Roland, Oops, I think this was my mistake, since I got your email addressed to "address@hidden". I'm not sure who forwarded it to that list, but I just assumed you had CC:ed that address, and I was apparently mistaken. NetCDF is similar to HDF5 in providing a data model and APIs for scientific data access. The upcoming version, netCDF-4, actually uses HDF5 as one of its possible storage layers. NetCDF-4 is supposed to offer a somewhat simpler API and simpler data model, but at the expense of not supporting some of the more complex HDF5 features.
