[Esip-preserve] [FOO] Foo Project moves to Google Spreadsheets

[Kenneth S. Casey]

Curt - I've been quiet on this list owing to lack of time to respond, but I did want to say that I think your FOO analysis is excellent and I've been following it closely!  Thanks so much. I think this approach is (1) extremely informative and (2) very comforting... comforting because the Group for High Resolution SST (http://ghrsst.org), a big international effort that produces standardized SST data from multiple satellites around the world that I participate in, just decided to use UUIDs embedded in a netCDF attribute for every single granule. It also plans to use DOIs for the collections being generated by the network of data providers from around the world.  The UUID usage is part of the new version of the "GHRSST Data Specification Version 2 (GDS2) " which was just published on October 1st.  The GDS version 1 produced about 30 collections and 1.5 million netCDF files, and there will be even more GDS2 data in just the next few years... so, we'll see how well this approach works...  

Ken
