Hello,

 It's possible to rename the nested variables in the ncml descriptions ?

 I deployed on the TDS server a ncml file that rename the nested variable 
"/HDFEOS/GRIDS/GeoGrid/Data_Fields/temperature" by 
"HDFEOS_GRIDS_GeoGrid_Data_Fields_temp" for the hdf5 file grid_1_2d.h5, but 
when i execute the request (OpenDAP service) :

http://climtest2.ipsl.polytechnique.fr:8080/thredds/dodsC/testAll-Hyrax-directory/data/ncml/TPs/tds/example.ncml.html

, the following response is appeared:

Error {
    code = 500;
    message = "New variable (HDFEOS_GRIDS_GeoGrid_Data_Fields_temp) must have 
datatype attribute";
};

 The ncml description is the following :

<?xml version="1.0" encoding="UTF-8"?>
<netcdf xmlns="http://www.unidata.ucar.edu/namespaces/netcdf/ncml-2.2"; 
location="/usr/share/hyrax/data/hdf5/grid_1_2d.h5">
  <variable name="HDFEOS_GRIDS_GeoGrid_Data_Fields_temp" 
orgName="/HDFEOS/GRIDS/GeoGrid/Data_Fields/temperature"/>
</netcdf>

I also tested with the following ncml descriptions :

<?xml version="1.0" encoding="UTF-8"?>
<netcdf xmlns="http://www.unidata.ucar.edu/namespaces/netcdf/ncml-2.2"; 
location="/usr/share/hyrax/data/hdf5/grid_1_2d.h5">
  <variable name="HDFEOS_GRIDS_GeoGrid_Data_Fields_temp" orgName="temperature"/>
</netcdf>

and with

<?xml version="1.0" encoding="UTF-8"?>
<netcdf xmlns="http://www.unidata.ucar.edu/namespaces/netcdf/ncml-2.2"; 
location="/usr/share/hyrax/data/hdf5/grid_1_2d.h5">
  <variable name="/HDFEOS/GRIDS/GeoGrid/Data_Fields/temp" 
orgName="/HDFEOS/GRIDS/GeoGrid/Data_Fields/temperature"/>
</netcdf>


Please find the file hdf5 in attachment.

Do you have ideas? Thank you very much for your help.
