Linda, George,

I have a recollection that CovJSON and CoverageJSON were different things.

CoverageJSON is the work done by Reading University and Jon Blower, and is a target for a candidate spec within OGC, currently on the list of things to be done in WCS SWG. There is now an OGC repo on GitHub. It started as an item in the W3C  SDWWG ‘Funnel’ and the WG (now IG) decided to push it over to OGC for Standardization.

Jon Blower did use ‘CovJSON’ as a short name for CoverageJSON, and I think that the WCS SWG also used it for a JSON encoding of output from a WCS CIS server, but with a different structure from Coverage JSON.

‘Cov’ has the potential to be confused with testing software outputting JSON.cov etc.

I support Linda in minimising editorial changes.

Chris

It seems to me that it would be a bit tricky to rename this document. It has been published as a W3C Note since 2017. We would have to update the W3C published doc as well. Of course, we are capable of doing that if we think it’s important.

BTW, the format is named CoverageJSON throughout the document, not just in the title. Would we want to change every occurrence?

I’m keep to hear opinions from this group!

Linda, all,

Regarding this document:
- https://www.w3.org/TR/covjson-overview/  (OGC 16-145)

There are several documents that provide encodings of Coverages in JSON.
It would be good if we had well known names for the documents.

To that end I recommend changing the title of 16-145 to match its URL:
- Change from:  Overview of the CoverageJSON format
- Change to:      Overview of the CovJSON format

Regards,
George

Dear group,

As requested in https://github.com/w3c/sdw/issues/1174 this is a Call for Consensus to release three W3C Notes the SDWWG has produced, as OGC Discussion papers. These Notes were published as W3C documents, and were assumed to have the status of OGC discussion papers - but internal processes mean they only appear in OGC document registers when the OGC Technical Committee (TC) votes to release them - and that step got missed.

Once the SDWIG decides we want to release these Notes as OGC discussion papers, the OGC TC can decide to publish them.

These are the three Notes:
- https://www.w3.org/TR/qb4st/  (OGC 16-142)
- https://www.w3.org/TR/2017/NOTE-eo-qb-20170928/  (OGC 16-125)
- https://www.w3.org/TR/covjson-overview/  (OGC 16-145)

Please let us know if you have any concerns by next Wednesday 29th April 2020.
Silence is considered consent.


Thanks,
Linda van den Brink
SDWIG Chair

No motion has been made to have CovJSON as a Discussion Paper.

The motion indicated by George was related to CovJSON, but not the one I’m looking for. The W3C Note about CoverageJSON was never published as an OGC Discussion paper, as was the intention. Was there ever a motion proposing to do that?

Yes, and there is a GitHub repo for the effort, but no charter for a SWG yet.

This motion was approved in the Singapore TC, Feb 2019:

•The Met Ocean DWG recommends that the OGC Technical Committee approve the development of a charter to establish a SWG to progress Coverage JSON to an OGC Implementation Standard.

     *   Coverage JSON fits the ISO concept but being schema-less, not completely WCS2.1/CIS1.1 compatible

     *   Motion: Don Sullivan, NASA

     *   Second: Chris Little, UK Met Office

     *   Discussion: the originator and implementer of the proposal (Jon Blower, Reading University) is willing to be involved in the process, but not take a lead. The NetCDF community also involved in using CoverageJSON .

     *   NOTUC There was no objection to unanimous consent

@lvdbrink yes, a motion from SDWIG is sufficient as it is an OGC subcommittee
