[Esip-documentation] ACDD 2-3 question (Conventions)

[Nan Galbraith via Esip-documentation]

Hi all -

Sorry if ACDD has hijacked this list ...

I'm going to modify the 'working version' text with regards to the 
Conventions
attribute, and I'm not completely comfortable going ahead without checking,
so let me know if you don't agree with this, please.

We've agreed to adopt the NUG recommendation for Conventions, and that's 
not
yet part of CF. The current (working) text might cause confusion on this:
> ACDD adopts all CF global attributes, with the exception of 
> institution; we
> specify creator_institution and publisher_institution to allow more 
> information
> about the data to be included. 

I'm going to modify it to say:
> ACDD 1.2 adopts all CF 1.6 global attributes with the exception of 
> 'institution'; we specify
> 'creator_institution' and 'publisher_institution',  to provide more 
> provenance information. We
> also modify the syntax of the 'Conventions' attribute; we adopt the 
> NUG recommendation
> to supply all conventions in a single attribute. This change has been 
> approved by the CF
> Conventions Committee and will be part of CF 1.7, which is not yet 
> published. 

Thanks - Nan
