Did you know something of the compatibility of HDF5 to HDF4 and HDF3.
If it's not compatibel then I believe it's no chance to get it
supported.

I asked many times for a newer version of netCDF. 3.6 is the latest
release
at the moment but in IDL it's 2.4.

There was a problem with the compatibilty of HDF in newer versions.
HDF,CDF and netCDF are the scientific dataformats which are included to
idl.
They won't upgrade only one format because they are added as package and
I always get the answer that they won't upgrade because of the
incompatibilty
of HDF formats which then occure.

Reimar

I don't have any inside scoop. But here is
a little tutorial for you on the subject:

1. Will RSI support HDF5?

Of course. RSI is in the data visualization business.
A huge amount of data is in HDF format. They have no
choice but to support it.

2. When will such support be in IDL?

About 6 months after you wanted it.

3. Why will support be delayed like this? My thesis
is due Tuesday!

Incorporating other people's software into your own
is a dirty, painful business. Mostly because that
software is shamefully under-documented and full of bugs.
It takes a certain amount of time and a great deal of
effort to sort through everything. And you have to
blend that effort with your own release schedule. It
all takes time. Usually more time than you hoped. And
you can bet more time than your customers wanted.

Cheers,

David

HDF5 is completely, totally and utterly different from HDF4. A whole
different ball of wax. The (NASA funded) project I work for uses HDF5
and IDL so we are going to need this, or we will have to abandon IDL.
Or write our own interface, of course, which is perfectly doable.

P.S. R (www.r-project.org) already has HDF5 support, see
