[Esip-documentation] Documentation Cluster Telecon TODAY

[Mike McCann]

I captured the chat.  Here it is:

from John Graybeal to Everyone:
http://wiki.esipfed.org/index.php/Attribute_Convention_for_Data_Discovery_1-2_Working
from Mike McCann to Ted Habermann (privately):
Not seeing a specific CF version number referenced. Doesn't that present an inconsistency e.g. with things like featureType and cdm_data_type?
from John Graybeal to Everyone:
http://wiki.esipfed.org/index.php/NetCDF_Utilities_Metadata_Handling
from Mike McCann to Everyone:
Not seeing a specific CF version number referenced. Doesn't that present an inconsistency e.g. with things like featureType and cdm_data_type?
from John Graybeal to Everyone:
ah -- potentially it does, though we tried to steer away from those particular conflicts
from John Graybeal to Everyone:
(the cdm_data_type was explicitly defined as different from the CF featureType)
from Ed Armstrong to Everyone:
my email is edward.m.armstrong at jpl.nasa.gov
from Ajay Krishnan to Everyone:
Mike, there is a 'Conventions' attribute under Highly Recommended. Wouldn't the CF version number be listed under that? 
from Mike McCann to Everyone:
Correct. But here is the inconsitency: CF-1.5 specifies cdm_data_type with a specific controlled vocabulary, CF-1.6 replaced it with featureType and a different controlled vocabulary. If a file follows CF-1.6 and ACDD isn't there an inconsistency?

For Discrete Sampling Geometry type data CF-1.6 is a much better convention than 1.5. I think it would be good to not use the older (and somewhat duplicative) terminology, as it is confusing to both metadata writers and readers.

>> In CF 1.5 there was a cdm_data_type with a specific controlled vocabulary; in CF 1.6 it was replaced by feature_type with a different controlled vocabulary. Since ACDD doesn't specify what CF convention applies, does this represent a potential conflict?
