Report on Roundtable XII June 4-6 2008Roundtable XII took place June 4-6, 2008, hosted by the University of Wisconsin in Madison, Wisconsin. The event was attended by 31 people from 22 organizations, including representatives from two observers (organizations attending a Roundtable to see if they wish to join). The Roundtable was dedicated to technical committee sessions, BOFs, and informal discussions and networking, with an all-hands Plenary meeting as the last item on Friday afternoon. The Technical Committee sessions were as usual organized sequentially, without competing parallel sessions, as is our standard practice to allow all attendees who wished to be involved in the discussions of each Technical Committee the opportunity to do so. UPDATE ON TECHNICAL COMMITTEES AND INITIATIVESTC CALDAV: TC CALDAV reported on its work since the last Roundtable and on implicit scheduling. In particular the discussion focused on calendar roles in preparation for the development of a draft protocol on role-based access control in CalDAV.TC EVENTPUB: TC EVENTPUB discussed venue information on vCard and the need to let the new vCard specification develop. vCard V4 as planned will include new property types for individual, organization, and group, and provide scope for resources. The TC will focus going forward on requirements and use cases around the public event space, and additionally on how that may relate to CalDAV. TC FREEBUSY: TC FREEBUSY reviewed its work on Freebusy URL. Key issues related to whether FBURL would be used to publish information, as well as meeting events and interactions with CalDAV. Going forward the TC will focus on developing a formal FBURL specification. TC IOPTEST: TC IOPTEST reported on the IOP test event just completed, and presented the proposed Virtual Test Lab as part of the TC MOBILE session. TC iSCHEDULE: TC iSCHEDULE was renamed (from TC REALTIME) to reflect its focus on the development of an HTTP-based protocol of iTIP, preliminarily called Internet Scheduling Protocol (iSCHEDULE). The session was primarily composed of reviewing authentication alternatives including a presentation on DKIM to determine a way forward for iSCHEDULE. The preliminary interest is in a TLS-like mechanism with credentials and a key distribution method derived from DKIM. TC MOBILE: TC MOBILE presented its work on extending the Mobile Calendar Interoperability Test Suite in the area of recurrences and formal definitions of mobile device capability levels. Plans for a Virtual Test Lab were presented by TC IOPTEST, and the second Mobile Interoperability Test Event was decided upon. TC TIMEZONE TC TIMEZONE presented the work to date on its draft proposal and RFC and will work towards having the proposal ready to present at the October Roundtable. TC USECASE: TC USECASE has been reviewing the topic of resources and finds little commonality between existing implementations. The TC will focus on a recommendation document for specific resource management issues. TC XML: TC XML, founded at the last Roundtable, reported on its work to date in developing a transform of iCalendar data to/from XML, particularly with respect to the size of an XML representation and the relative friendliness of the XML created. CALCONNECT INTEROPERABILITY TEST EVENTS: Participants in the IOP test included Apple, Mozilla, RPI (Bedework), Scalix, and Yahoo!/Zimbra. Results from the event will be posted at Past IOP Reports as soon as they are collated and prepared. BOFS: The major BOF was on preparing for an enhanced Technology Preview at the October event, and to what degree CalConnect should be trying to conduct a public event with press representatives. As before, we will invite a small number of selected individuals from the media with an interest in calendaring to the Technical Preview in October. NEW INITIATIVES:
