OMA MEM liaison

• Response to specific questions
• will study the possibility of a shorter list that
  is mandatory for the MEM enabler for OMA STI. We
  will provide IETF LEMONADE an update on this
  after our next meeting.
• only notification and send/receive roundtrip
  delay is of concern at this point.
• message recall is still a requirement.
  Specifically, that the client be able to request
  a recall and that success/failure be indicated
  back. MWG-MEM will let IETF know if any further
  work is requested.

Proposed Mandatory list of Conversions to support
for draft-ietf-lemonade-convert-xx

• Proposal from Alexey / Chris / Stephane
• HTML to Text
• Details to be worked out from STI doc etc
• HTML, XHTML,
• Doc structure
• Tables
• Images
• image/gif, image/jpeg and image/png (un- / no
  more encumbered)
• Parameters from STI
• Size limit (i.e. reduce quality),
• width,
• height,
• resize directive (crop, stretch, aspect ratio)
• Note we have not considered depth, is this
  needed?

21
Proposed Mandatory list of Conversions to support
for draft-ietf-lemonade-convert-xx

• Continued
• Audio
• Not considered because of lack of widely used
  unencumbered codecs
• To be treated as others
• Others (including, proprietary document formats,
  audio, video, )
• To be described via MIME types and STI parameters
• May not be supported by server gt behavior
  described in draft
• Should be validated with device manufacturers and
  operators

22
Additional thoughts for CONVERT

• Not part of the proposal from task force (two
  previous slides)
• Add a compression transformation for object level
  compression based on discussions of Monday
• Will take to the list

Reconnect Status

• Got New draft-05
• Did Not Last Call (Next Slide)
• After Meeting
• Depends on
• CONDSTORE, expunged,
• Need implementations of 05

25
Reconnect Issues

• What state is to be saved by the server?
• Address some edge cases, e.g. "SID, SID
  ltsession-idgt, SID". Is the last operation "create
  new session", or should it be noop?
• Figure out if RECONNECT should depend on EXPUNGED
  extension (extension to send a compressed list of
  expunged messages).
• Is LOGOUT (PRESERVE) needed?
• Do we need to add a new DELETESID command (i.e. a
  command to delete an existing session without
  logging out)?

26
RFC2192bis IMAPURL Status

• Updated text on mailbox naming scope field
  (section 3.1), more changes to this section
  needed.
• Updated section 3.2 to describe anonymous logins
  and client behaviour if it sees LOGINDISABLED
  IMAP capability.
• Reworked section 5 (listing IMAP server content)
  to talk about NAMESPACE command.
• Removed references to Content-Base header, as it
  was obsoleted. Updated reference for
  Content-Location header to point to MHTML
•  Allow for UTF-8 (as non-synchronizing literals)
  in Search criteria
•  Clarified that IMAP usernames and Search
  criteria can contain UTF-8 data.
•  Fixed error in ABNF for partial body range.
•  Added IANA considerations section (more work is
  needed).
•  Updated references

27
RFC2192bis Issues

• Include URLAUTH IMAP URL extension into this
  draft?
• Extend syntax to allow for BINARY, SEARCH return
  options (ESEARCH extensions), LIST-EXTENDED,
  etc.? (I think the answer to this question is
  yes, the question if we want to put all mentioned
  IMAP URL extensions in 2192bis)
• ABNF Error Will Be Fixed in Next Version

28
