Roy Lowry has mentioned in the past that the official maintainer is at STFC, though I can?t remember who (female if I remember right) but it was a very part-time job, and there are no canonical URIs.
With netCDF coming under the OGC banner, it is not clear if this also includes CF (probably not), but there is an opportunity here.

I pass this along to the CF list for obvious reasons.

Hi Simon,
Thanks for the suggestion. That approach would seem to have many advantages, but my sense is that there would be some concerns among some members of the CF conventions community. But, with Russ Rew and John Caron having left Unidata, I need to figure out a good liaison with whom to broach the topic.
Have you brought it up with any of the active CF brethren?

Hi Ben ?
Regarding CF convention terms ? would there be any interest in seeing these hosted by OGC with a permanent URI per item?
As I think you are aware, we are moving the OGC system to a registry in which maintenance of the content can be delegated to appropriate managers. Mark Hedley (who was on the program here) is very familiar with this system too.
Take a look at our test system here
http://registry.it.csiro.au/def
We have a bunch of sandboxes here
http://registry.it.csiro.au/sandbox so I could create one there for netCDF to do some testing.

Subject: [NetCDF.swg] OGC NetCDF SWG DIscussions
Hello all:
First and foremost, I thank Lorenzo Bigagli for chairing the OGC TC NetCDF SWG session at the TC meetings in Nottingham. Stefano and I were unable to attend those meetings. The items from his meeting summary for the closing plenary are included below along with discussion topics that have arisen in email and other interactions since the meeting.

============================================================================================================
Nottingham TC NetCDF SWG Session Summary Items
Agenda:
1. NetCDF-CF ? ISO 19115 conceptual model mapping ? Stefano Nativi (CNR) [skipped].ISO Spatial referencing for netCDF ? Mark Hedley (MetOffice)
2. NetCDF Uncertainty Conventions (netCDF-U) update ? Lorenzo Bigagli (CNR)
3. Update on MetOceans interactions
4. Update on WCS interaction
5. AOB
Issues:
1. How to apply Well Known Text for Coordinate Reference Systems to CF-netCDF
o Consider OGC standards to map CF-netCDF to ISO terms
2. OGC may investigate a standardised approach to encoding spatial coordinates and spatial referencing in netCDF
o Possibly applicable also to other formats (HDF, JSON)
o May be provided back to CF as a basis for a revision of the CF Conventions
o Equivalent to OGC Coverage Implementation Schema, but for NetCDF
Actions:
? Ask OGC staff about publishing revised NetCDF-U Conventions DP as corrigendum
? Continue gathering NetCDF-U use-cases and usage examples
o Aim: NetCDF-U Best Practices document
================================================================
Items from follow up discussions
The items below have come up in follow up discussions after the Nottingham meetings. Many of them warrant further discussion at the NetCDF session at the next OGC TC meeting in Sydney.
Issue From the Nottingham Meeting Summary
"OGC may investigate a standardised approach to encoding spatial coordinates and spatial referencing in netCDF." In practice, how do we to follow up on this issue? Is it an item for the netCDF SWG or an ongoing action in some other WG? Is it related to the more general OGC effort to ?standardize? the CRS specification, introducing N-Dimensions?
ESA Prod Trees Project Completion
ESA Prod Trees project is now complete and plans to contribute its work to the OGC NetCDF SWG. CNR has already given of presentations on that work in earlier OGC TC meetings. It will be useful to continue efforts to harmonize this and other ongoing efforts within the OGC SWG activity and establish extended conventions supporting the Geosciences (Earth Sciences) Community. Likewise it is important to continuing to ensure that these conventions do not conflict with other netCDF conventions such as CF. (Note that CF conventions are already established as OGC standards.)
Related Projects
Other projects include conventions and other netCDF-related development efforts, e.g.:
? ODIP (Ocean Data Interoperability Platform), an EU Horizon 2020 project.
? EarthCube IA: Advancing netCDF-CF for the Geoscience Community, a recently funded US NSF Earthcube project. .
http://www.nsf.gov/awardsearch/showAward?AWD_ID=1541031
? the work of the the National Computational Infrastructure at the Australian National University.
Key questions ares how to coordinate all these efforts and, especially, where do we find the resources to do so?
Name of Recently Adopted OGC netCDF Extension Standard
A suggestion has been made that the name of our recently adopted NetCDF spec which references the coverages spec as "GML coverage model" which, as per a decision at the Barcelona TC, has been renamed to "Coverage Implementation Schema" (CIS). The idea is to avoid confusion for those who might read the two standards. However, there is some question as to whether this is completely accurate since the netCDF extension standard involves more than the Coverage Implementation Schema.
