[Esip-documentation] [DIWG] netcdf containers

[Ted Habermann via Esip-documentation]

Mark,

Thanks for the follow-up presentation on netCDF containers (http://marqh.github.io/ncContainers/build/html/intent.html). I am cc’ing two groups in the US that are also interested in this discussion:
the NASA working group I mentioned, and the ESIP Documentation Cluster. The second group is also interested in applying these ideas to the metadata in these files. There is an older (and maybe a bit out-of-date) discussion of some of these ideas at http://wiki.esipfed.org/index.php/NetCDF,_HDF,_and_ISO_Metadata.

The second group is also interested exploring conventional approaches to flattening files with groups. Most of our discussions have focused on concatenating group and variable names with some sort of delimiter(s). The approach you show in the Vector example at http://marqh.github.io/ncContainers/build/html/examples/vectorfield.html with container_members that are containers, might be an approach that avoids this somewhat fragile approach…

Mark,

Thanks for keeping me up-tp-date on this. I am sharing it with a NASA working group on interoperability as I know they will be interested...

Hello all

I have made some small updates to the content:
http://marqh.github.io/ncContainers/build/html/index.html

based on feedback from a colleague here, which deal with some inconsistencies and clarity; nothing major has changed.

I would hugely value any feedback on the details of this proposal, whether it's aim has merit and potential avenues to pursue.

many thanks
mark

Subject: netcdf containers

Hello

Following on from the discussions at the recent OGC TC on CF NetCDF I have reworked my draft proposal for netCDF containers

I have attempted to illustrate how they may support:

uncertainty
netcdf4 groups in netcdf3-classic
vector fields

I would very much welcome some informal feedback from each of you, as you each expressed interest from different points of view during the OGC meeting

I have prepared my first draft here:
http://marqh.github.io/ncContainers/build/html/index.html

Please feel free to browse the source:
https://github.com/marqh/ncContainers

and provide any comments on my private project issue tracker
https://github.com/marqh/ncContainers/issues

I do not know how this may be able to address some of the issues of the community but it seemed worth pursuing following the Washington discussions

I would like to discuss ways to perhaps take this on, if it is viewed to have merit, potential, not be so full of holes it's not worth further effort.

All input gratefully received

mark
