[Esip-documentation] Fwd: [esip-semantictech] ACDD vocab as RDF

Tue Nov 13 12:39:37 EST 2018

Hi Folks,

I’m fine with going with option 2 to clearly separate different vocabularies from NUG, CF and ACDD. But there is still the problem of how to best document overlap…. I believe there was a little misinformation earlier in the thread.  For example, attributes “title”, and “Conventions”  are clearly and uniquely defined and assigned in ACDD and CF even if they have the same language.  For example see here:

  http://wiki.esipfed.org/index.php/Attribute_Convention_for_Data_Discovery_1-3 (look for Highly Recommended Global Attributes)

Hi Jonathan, all,

Yes, Unidata could host something to capture the list of attributes included in NUG. We've started looking at making the NUG a bit more standalone (less intertwined with the C library docs). This might fit right in with that effort.

Cheers,

Ethan

Hi Dave, Edward, and Nan,

Thanks for that. Also, capturing semantics about global vs. variable level properties would be good too.

On representing properties... It would be ideal if we had CF, NUG and ACDD properties represented too. We're in a bootstrapping phase at the moment - these do not yet exist for the 3 conventions. The issue also is around publishing resources that are governed by the respective communities. I wonder if I could ask which of the following options is preferable for capturing attributes used across CF, ACDD and the NetCDF user's guide - (where <=> is something like a sameAs or exactMatch relationship) ?

-Option 1: Include equivalence statements across communities-
acdd:title <=> cf:title <=> nug:title
acdd:Conventions <=> cf:Conventions <=> nug:Conventions

or

-Option 2: Publish -
nug:title
nug:Conventions

@Ethan - would Unidata consider hosting a Github repo with a CSV or RDF files for capturing the list of attributes included in the NUG? The ESIP COR might be an option for hosting Linked Data descriptions for them like http://cor.esipfed.org/ont/~jyu/test-acdd

Regards,
Jonathan

I'd like to clarify that we have printed some attributes in our documentation (e.g. title, source, Conventions) that are not just identical to CF or NUG, but actually belong to those conventions, not to ACDD.  The text may not be quite as explicit as it was at one point, but we defer to CF  or NUG for these definitions, and don't claim ownership of them. They're included in our documentation because they're such a necessary part of discovery.

At least that's my take on this.

Cheers - Nan
