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
