2.1.  TC CALDAV

TC CALDAV provided a status update on the various IETF Internet Drafts relevant to CalDAV. The ZideOne Outlook to CalDAV connector was demonstrated. An open discussion was held on several projects for extensions to CalDAV which will be part of the TC’s remit going forward.

2.2.  TC EVENTPUB

TC EVENTPUB discussed the interactions between the TC and the shared calendar workshop discussions throughout much of the Roundtable, in particular public events use cases previously developed by the TC. The TC also discussed the state of work in its document describing how vCard can be used with iCalendar. A decision was made to put the TC on hold pending completion of vCard 4.0 work in the IETF, when it can be integrated into the EVENTPUB resource proposal.

2.3.  TC FREEBUSY

TC FREEBUSY reviewed the publication of the Freebusy Read URL proposal and discussed work that has begun on a proposal for support of consensus scheduling.

2.4.  TC IOPTEST

TC IOPTEST reported on the IOP test event just completed (elsewhere in this report) and on plans for an iCalendar parser and further use of the Virtual Test Lab Facility. The TC expects that testing will begin in October in new areas such as Freebusy Read URL, CardDAV, and the new Timezone service and registry proposals (the first two were tested informally this time; the Timezone protocols may begin informal testing in October).

2.5.  TC iSCHEDULE

TC iSCHEDULE discussed the progress on the protocol and had an open discussion on methods of deploying the iSchedule protocol in various scenarios.

2.6.  TC MOBILE

TC MOBILE discussed its work on a Vision for Mobile Calendar, and held an open discussion on the use cases for the document. An agreement was reached on the desirability of a proposed document describing how CalDAV could effectively be used by mobile devices. The Technical Committee is looking for a new Chair, following the reassignment of the previous Chair within his organization.

2.7.  TC RESOURCE

TC RESOURCE was established after the last Roundtable and has begun work on defining a schema to represent resource attributes to enhance interoperability of resource data. A consensus was reached in the discussion to use an abstract schema a bit more complicated than name-value pairs, with an LDAP mapping example at the end of the document.

2.8.  TC TIMEZONE

TC TIMEZONE presented work to date on its draft RFCs on Timezone Registry and Timezone Service. It seems likely that there will be at least three trial implementations available for interoperability testing at the October C.I.T.E.

2.9.  TC USECASE

TC USECASE presented an overview of its three Resouce documents which have just completed Last Call, and a vote to publish was taken at the TC Wrapup session at the end of Roundtable XV. The documents are published at:

The TC will begin work in three areas new areas:

2.10.  TC XML

The protocol for a round-trippable transform of iCalendar data to/from XML has been completed and approved for publication, and has been submitted to the IETF as an Internet Draft; see iCalendar XML Representation. A visitor from the OASIS oBIX working group was present and discussed their interest in taking advantage of this work in the devleopment of their WS calendar specification for intelligent building management. TX XML expects to begin next on a JSON document for the specification.
