Dear CF Conventions People,

Some of you may be aware of the Spatio-Temporal Asset Catalog (STAC)
project.
https://github.com/radiantearth/stac-spec/
STAC is basically a .json specification which aims to standardize the way
geospatial assets are exposed online and queried. It originated from the
geospatial imaging community, and is described in this blog post by Chris
Holmes:
https://medium.com/radiant-earth-insights/announcing-the-spatiotemporal-asset-catalog-stac-specification-1db58820b9cf

There is currently some discussion on the STAC repo about how STAC could be
useful for netCDF-type data.
https://github.com/radiantearth/stac-spec/issues/366
This is a technology space that is currently occupied by THREDDS and
OpenDAP. But something like STAC could be very useful for our community,
especially as more netCDF-style data moves into the cloud.

In particular, there is a proposed extension to STAC to describe "data
cubes," which is roughly what geospatial imaging people call netCDF-type
gridded datasets:
https://github.com/radiantearth/stac-spec/pull/361

I wanted to email this mailing list to see if someone from the CF community
could weigh in on this proposed standard. More generally, if the CF /
netCDF community wanted to engage with the STAC people more broadly, I
think there is quite a bit of potential.

Cheers,
Ryan Abernathey
