HDF data Import

Hi group,

I use the HDF  Import functionality of Mathematica and would like to
ask for your experiences. My biggest concern is that the HDF4 format
is only partly functional. So far it is only possible to access SD
(scientific Data, i.e. arrays of data) Datasets. But HDF4 consists
also of AN Data (annotations), VData (customized tables) and VGroups.
Pure SD data is somewhat useless if I can not access the explanatory
metadata in the file.  I need to access HDF files containing SD and VD
fields. So far I can only get the SD fields. Has anybody come up with
an updated HDF interface or a workaround via direct BinaryRead ? HDF5
is somewhat similar because compound expressions are nor supported.
Any ideas or experiences?

Thanks,

Markus
