Subject: RE: Agenda for tomorrows teleconference

All -
It has been a busy week of email discussion on a variety of topics!  So, we will have a full agenda tomorrow for our 11:30 AM EST teleconference.
Possible agenda items:
1. Discussion of Dave Danko's 3 suggested approaches (See below) for enhancements to CAP for handling coordinate reference systems. Our recommendation would result in a change request proposal for a new work item after CAP 1.0 has been approved.
2. Discussion on RAINS in Oregon and whether we should seek collaboration with them (at some level)
3. Thoughts on CAP registries and what that means (like implications moving forward in terms of access to a CRS registry (there is one!)
4. Any other hot topic :-)
