Agenda:

* CBOR specification status : Carsten
  https://tools.ietf.org/html/draft-ietf-cbor-7049bis-13

  Summary from last meeting:
  - #177 Review the list for history
  - #176 Good support on the call for this to be added.  Need more discussion on how it is used.  Bring to mailing list.
  - Implementers review status
  - Next submission by the end of the month, then ready to ship
  CB: Expects to see some more comments coming in from at least one additional impementor
  Did not manage to make much in the way of progress
Expects to have about 4 days of work to get the next version out
  FP: Looked at the mailing list for the DE update information.  Could not find the minutes for the discussion.
  
  Will get back to this before EOM.


* Date and time tag document: Mike  (no slides)
  https://tools.ietf.org/html/draft-jones-cbor-date-tag-01
  
  MJ:  Asks the chairs/WG for the expected process to get the documents stable.
  CB: What is the status that we give these documents.  Information or Standards
  More of an issue in terms of additional documents referencing for the downref list.
Might allow documents to reference the registery directly rather than to the document.
Should get some AD perspective on this question
Still believes that we should look at doing a consolidation document for having an archive of 
tags that are currently defined in places like a website.
  MJ: Would like this to be done for ISO to be able to reference quickly.
  Would like to request adoption from the WG.
CB: Agree that document would be way to go
FP: we can start WG adoption call.  Asks for poll of people who have read document
(CB, HB, MJ, JS, LL, ID, PY, FP)
  LL: Does worry about the possiblity of having too many types of dates and ties
  HB: Dates and times are very different things - doesn't expect this to be an issue

* CDDL freezer: Carsten
  https://tools.ietf.org/html/draft-bormann-cbor-cddl-freezer-03 
  HB: How do we compartmentize this?  What else should be in the first chunk.
FP:  Related to the chairs project to try and get feedback on rquests for features
How urgent is this compared to the other items on the list.
JS: Would prefer not to have a huge document to make things wait on the slowest item
FP; Still have an issue of same author may cause issues
CB: I think that the JSON format needs to get pulled in sooner
Module interface is highest priority, but it is not clear how to do this.
HB: Suggest bundling controls and make the JSON format separate
CB: What other controls are ready to go?
HB: Bitfield control, 
CB: That looks to be a can of worms - Lots of design space to cover this
ABNF is well understood
HB: Start a draft with all controls and then trim out things that are not progressing.
Would like to see a more fleshed out cut design
ID: Would probably favor several documents.  Really would like to see ABNF control done.
FP: CB to submit individual draft for comments to start working on in the group.
Can rediscuss scope as part of the adoption call.
CB: Need to get a proposal for import/export thing.

  Summary from last meeting:
  - Please read section 4
