LMAP WG Interim, 12 February 2015

Chairs: Dan Romascanu, Jason Weil
Minutes: Barbara Stark, Joan Luciani

Participants: barbara Stark, Jason Weil, Joan Luciani, Marcelo Bagnulo, Trevor
Burbridge, Vajbhav Bajpai, Dan Romascanu

Summary of Action Items
--------------------------------
* Trevor Burbridge it going to send email to the list wrt proposed Version 04
changes for the Information Model draft. He will request that feedback be given
within 7 days and then he will update the draft accordingly. This email should
also include a clarification on the relationship between the running task and
the reporting task, particularly in the (immediate state), i.e. he will address
the concern/question raised by Juergen S. as part of this email on proposed
changes.

* Barbara S. will update the Protocol Criteria document by end of February.
This should give folks time to review it for the March IETF meeting.

* Dan will make a FINAL call for NEW LMAP protocols on the LMAP list and also
at the IETF level.  The request will ask for any new LMAP protocols to be
documented in an Internet draft.   The deadline for introducing a new LMAP
protocol will be by the IETF WG submission deadline for the Dallas meeting of
March 9th, 2015. The goal is that any new protocol will be documented in an
Internet draft so that folks have a chance to read about it before the Dallas
meeting.   Then the new protocol can be discussed at the Dallas IETF meeting,
however, flexibility will be given such that if someone comes forward on the
LMAP mail list with the name of a new protocol and references, that this will
also be considered as having met the March 9 deadline, although an Internet
Draft is preferable. NB: Since the protocol criteria draft is undergoing some
changes, flexibility (i.e. a minimum of announcing a new protocol with
references in an email to the LMAP WG by March 9, 2015) will be acceptable.

* Dan and Jason to update the LMAP Working Group milestones by the Dallas IETF
Meeting.

done.

Discussion on CP-MUST-1 and CP-MUST-2
Dan echoed Juergen's concern of over-engineering the criteria, but wanted these
to remain in the document.

MUCH DISCUSSION about making a FINAL call for any new LMAP protocols (See
action item above.)

CP-MUST-3 -- need to agree with framework.  Barbara to check wording wrt
"secure credentials"

CP-DIFF-4 (added "yes is better")

CP-DIFF-8 Dan requested this be dropped or merged with CP-DIFF-10

CP-DIFF-10 add examples, (compilers, tutorials, open source, etc.)

CP-DIFF-12 goes with CP-DIFF-11

CP-DIFF-13 Dan questioned whether or not this was necessary as people need to
supply an Internet draft on their protocol

RP-MUST-1
Dan:  Maybe framework doc needs to be changed
Barbara:  Maybe ask on the list

Jason W. asked about congestion control.
Dan suggests adding that to the criteria
Barbara: added question in draft

Dan asked Barbara about timeframe for updating the draft, especially since the
"call for protocols" will be soon. Barbara will update Draft by end of Feb. 
(See Acton Items above.)
