I can't figure out the command to Export an HDF5 file from Mathematica that includes both an Attribute and a DataFormat. I can do one or the other, but not both.

How can I export to HDF5 with a specific Datatype ("DataFormat")

Ok, after trying a few more things, the following works:

Export["test.h5", {"Datasets" -> {"/m1" -> {{1, 2}, {2, 3}}, "/m2" -> {{10, 
11}, {12, 13}}}, "DataFormat" -> {"UnsignedInteger16", "UnsignedInteger8"}, 
"Attributes" -> {"m1" -> {"m1Attribute" -> "testAttribute"}}}, "Rules"]

Then Import["test.h5", "DataFormat"] and Import["test.h5", "Attributes"] give <|"/m1" -> "UnsignedInteger16", "/m2" -> "UnsignedInteger8"|> and <|"/" -> <||>, "/m1" -> <|"m1Attribute" -> {"testAttribute"}|>, "/m2" -> <||>|>, respectively.

    $\begingroup$ One possible issue here is that currently export of group attributes does not work correctly. It does not affect your example, though. $\endgroup$ – rafalc Dec 12 '17 at 14:01
