I agree that using something like this would be desirable.

But I think Octave needs the other features as well, to provide
compatibility with Matlab's binary I/O.  I believe that this is also
important, since people seem to want Octave to be compatible.

If there is a (mostly) standard library for binary data that is freely
available, I would like to use it.  I would even drop Octave's own
binary format in favor of the new method if it is easy to write a
conversion program (something that I expect should not be too hard).

In addition to HDF, I have heard about netCDF, which also looks like
it might be a reasonable alternative.

Can anyone comment on which data file formats (netCDF, HDF, or others)
are likely to be become standards? 

(Please e-mail me directly unless you really think it is something
that would be of interest to most people who read help-octave.)
