Hi Phil,
while I agree with you that the only clean solution would have to be
defined in the netcdf API itself (not in CF), I don't think that groups are
what we are looking for here. This namespace thing is entirely related to
attributes, while groups are a variable concept. What would help were
"hierarchical attributes", so that one could define metadata "groups" just as
in an XML file. Possibly something like
float myvar(dim1, dim2)
cf_attributes:
standard_name: "..."
units: "..."
OSD_attributes:
measurement_principle: "..."
etc.pp. -- only this would make reading netcdf files a wee bit more complicated
;-(
Best regards,
Martin
