Re: [core] CORE Draft Agenda for IETF 77

Hi Don,

Sure, I think we should discuss these points during the WG meeting and I'd be happy to include them in my slot on CoAP. We have a (currently blank) resource discovery section in the I-D, and need to move forward on that as a result of Anaheim. Same goes for subscription.

There are two issues to be considered there:
1. Discovery of CoAP resources, this is clearly in the charter and could include both directory agent/user agent models.
2. Pointing to a service discovery technique that should be used in case you don't even know if/who is running a CoAP service is something we can do. We can't modify or create a protocol for this without re-chartering.

Could I suggest that you help me out with a few slides regarding resource discovery (1.)? I'll be on vacation for the next week, but let's do this together in the first days of Anaheim.
