Hi Abdelrezzak BARA:

HDFEOS/GRIDS/GeoGrid/Data_Fields/temperature

becuase the CDM replaces an internal ' ' with an '_'.

Apparently the Hyrax server doesnt do that.

Hello,

  I deployed on the TDS server a file hdf5 which contains the variable
whose the name is (dont le nom est) "/HDFEOS/GRIDS/GeoGrid/Data
Fields/temperature" (it's a composed name). It's a array of 32 bit Reals
[YDim = 0..3][XDim = 0..7]. The origine name of the variable is temperature.

when I execute the request with the web browser :

http://host-sever:port/thredds/dodsC/......../grid_1_2d.h5.ascii?/HDFEOS/GRIDS/GeoGrid/Data%20Fields/temperature[0:1:3][0:1:7]
<http://climtest2.ipsl.polytechnique.fr:8080/thredds/dodsC/testAll-Hyrax-directory/data/hdf5/grid_1_2d.h5.ascii?/HDFEOS/GRIDS/GeoGrid/Data%20Fields/temperature[0:1:3][0:1:7]>

, the following error is appeared:

Error {code = 2;message = "The variable `/HDFEOS/GRIDS/GeoGrid/Data
Fields/temperature' was not found in the dataset.";};

I also tested the following requests :

http://host-sever:port/thredds/dodsC/......../grid_1_2d.h5.ascii?temperature[0:1:3][0:1:7]
<http://climtest2.ipsl.polytechnique.fr:8080/thredds/dodsC/testAll-Hyrax-directory/data/hdf5/grid_1_2d.h5.ascii?/HDFEOS/GRIDS/GeoGrid/Data%20Fields/temperature[0:1:3][0:1:7]>
http://host-sever:port/thredds/dodsC/......../grid_1_2d.h5.ascii?_HDFEOS_GRIDS_GeoGrid_Data%20Fields_temperature[0:1:3][0:1:7]
<http://climtest2.ipsl.polytechnique.fr:8080/thredds/dodsC/testAll-Hyrax-directory/data/hdf5/grid_1_2d.h5.ascii?/HDFEOS/GRIDS/GeoGrid/Data%20Fields/temperature[0:1:3][0:1:7]>

, The same error is generated.

For indication, The Hyrax server manages these compozed names well. The
following request passes well :

http://host-sever:port/opendap/......../grid_1_2d.h5.ascii?temperature[0:1:3][0:1:7]
<http://climtest2.ipsl.polytechnique.fr:8080/thredds/dodsC/testAll-Hyrax-directory/data/hdf5/grid_1_2d.h5.ascii?/HDFEOS/GRIDS/GeoGrid/Data%20Fields/temperature[0:1:3][0:1:7]>

Have you idea and solutions for resolve this problem with the TDS server?

Thank you very much for your help.

Abdelrezzak BARA.
