[CF-metadata] Usage of the 'Conventions' attribute
Dear All, Currently, the 'Conventions' attribute is restricted to be a global attribute. There is currently a requirement to label multiple QC flag variables following different conventions with their source convention and having the 'Conventions' attribute as a variable attribute for these non-co-ordinate variables would seem a convenient and consistent mechanism. Is there any support for or objections to this suggestion? Cheers, Roy. Please note that I now work part-time from Tuesday to Thursday. E-mail response on other days is possible but not guaranteed!

Re: [CF-metadata] Usage of the 'Conventions' attribute
I'm currently working with a group looking at profiling glider date a files from multiple countries. We've identified a similar need to differentiate qc tests on a per variable basis. I support the idea and the problem and I suppose one solution is the conventions attribute.

Re: [CF-metadata] Usage of the 'Conventions' attribute
Hi Roy - As far as I know, there is nothing to prevent you from having Conventions attributes other than the global one. Only the global attribute is part of CF, but you could certainly implement similar syntax in Conventions attributes for multiple variables. Or are you looking for more of a formal acceptance of a variable- level Conventions attribute? You're not proposing to replace the flag_values and flag_meanings attributes with this reference to an external QC flag convention, by any chance? That would be a difficult step.

Re: [CF-metadata] Usage of the 'Conventions' attribute
Hi Nan, I am definitely NOT trying to replace the flag_values and flag_meanings attributes - the Conventions attribute would be in addition. It's more formal acceptance of what is becoming a de facto practice that I'm after. Cheers, Roy. Please note that I now work part-time from Tuesday to Thursday.
