Publish NUG attribute names as Linked resources

[marqh]

Hello netCDF folks

I was at an OGC meeting where @ethanrd was describing some work on the NUG

I would like to highlight and discuss with the community one facet that would be massively useful for our group, working on https://github.com/opengeospatial/netcdf-ld and a valuable way to establish good practice for publishing controlled terms

we looked a while ago at the now defunct (404ing) resource https://www.unidata.ucar.edu/software/netcdf/docs/attribute_conventions.html

it appears that there are 11 controlled attribute names within the NUG

We extracted these and presented them in a linked data registry which we own, but which has no links to Unidata nor netCDF
http://def.scitools.org.uk/NetCDF

this is illustrative, but absolutely not definitive nor endorsed by netCDF / Unidata

The crucial facets of this approach are:

1. each individual attribute term is defined by a fully qualified unique URI
2. rdf:type is defined as rdfs:Property
3. rdfs:domain is defined as https://www.opengis.net/def/binary-array-ld/Resource
4. rdfs:range is defined as rdf:Literal
   • for any attribute where the value is not from a controlled vocabulary (all of NUG terms, I think)

we would like to investigate with Unidata how to go about establishing that this list is valid, and how to publish the list as a linked data resource set using a controlled and authoritative namespace that demonstrates that a new published list is an authoritative

many thanks
