[ESIP-all] New ESIP Cluster proposal - request for comment

[Ethan Davis]

Hi all,

The new ESIP Data Model cluster has been set up. We have a wiki page [1]
and an email list (please sign up for the list here [2]).

George: Thanks for the pointer to Testbed 14. Yes, we should definitely use
this cluster as a venue for discussion of that effort.

Thanks,

Ethan
