We (Dojo toolkit) have been using REST Channels [1] for clients to
receive real-time notifications of resource updates. Could/should we
use the "hub" relation for resources to reference the URI that
Dojo/clients connect to for updates? And if so it seems like "updates"
or "notifications" would be a more generic, fitting term than "hub"
(but "hub" isn't bad).
