3.7. TC CALDAV

Several ongoing topics were presented and discussed, including

• Rich Capabilities — the basic outline was discussed. Current issues including backwards compatibility with the DAV header and efficient change notification will be considered by the TC.

• Storing encrypted data on a CalDAV server — input from the IETF was that it was important to expose this work early, and the TC will look into creating a problem statement to take to an appropriate IETF WAG.

• Draft Events — an outline of a possible solution was presented and discussed, but the feeling was that the approach was overly complex; the TC will work on a more streamlined approach.

• Group scheduling — a new topic from the interoperability test event earlier in the week. Discussed how scheduling with groups and “self-invite” modes of scheduling could be implemented in iCalendar and CardDAV; there is interest in the TC in working in this area.

• New issue in the meeting — possibility of defining a simple HTTP-based iTIP response option so that web services can implement a simple request/response scheduling feature without having to implement an e-mail service.

• REMOVED PARTSTAT — another issue from the interoperability testing, the addition of a new REMOVED partstat to allow attendees (VPOLL) voters) to have themselves entirely removed from an invite rather than just decline. This will probably be work on in TC FREEBUSY.
