Hello!I am using the NetCDF-Java Library to parse TDS configuration THREDDS catalogs and I've run into a sticky point that I'm hoping you can help sort out. I have an example TDS configuration file which I can read in and validate using the NetCDF-Java Library, but a certain piece of information I'm expecting to see is either NOT there, or in a place I'm not looking. The piece of information is a dataSize for a dataset. The twist here is that the dataSize is embedded within a metadata tag thusly:
<dataset name="Atmosphere" ID="cgcm3.1_t47_atmos" serviceName="gridded">
<metadata inherited="false">
<dataSize
units="Kbytes">439.78</dataSize>
</metadata>
</dataset>
The specification says that a <dataset> can contain an element of the
threddsMetadataGroup which contains <metadata> and <metadata> can
contain elements of the threddsMetadataGroup which includes
<dataSize>. However when I look at the InvDatasetImpl that this
example produces, getDataSize() returns 0.0 and I cannot see the size
in any of the metadata structures.
My questions are: - Is this a valid structure?- If it is a valid structure, is there a reason the size element of an InvDatasetImpl is not populated with the dataSize from this structure?
- If it isn't a valid structure, can that somehow be noted or changed in the specification?
Thanks for your time, Hannah Wilcox Software Engineer in the VETS group hannah@xxxxxxxx
