Foreword

The Calendaring and Scheduling Consortium (“CalConnect”) is a global non-profit organization with the aim to facilitate interoperability of technologies across user-centric systems and applications.

CalConnect works closely with liaison partners including international organizations such as ISO, OASIS and M3AAWG.

Introduction

Roundtable X and the accompanying IOP Test Event took place September 17-21, hosted by The Massachusetts Institute of Technology, in Cambridge, Massachusetts. The event was attended by 43 representatives from 31 organizations, including representatives from three observers (organizations attending a Roundtable to see if they wish to join).

The CalConnect Interoperability Test Event (C.I.T.E.) was held immediately prior to the Roundtable, running Monday noon through Wednesday noon, September 17-19. Nine (9) organizations participated in this event, performing interoperability testing between their calendaring and scheduling implementations. A report on the IOP Test Event will be published as soon as possible.

In conjunction with this Roundtable, CalConnect hosted a one-day open vCard Workshop on Tuesday, September 18th. The vCard Workshop was attended by about 20 people. A report on the workshop together with presentations and other materials may be found at vCard Workshop Report.

Roundtable X, attended by 43 representatives from 35 organizations, including 4 observers ran Wednesday afternoon, all day Thursday, and Friday morning. Wednesday afternoon began with a Technology Preview demonstrating live interoperability in the areas of CalDAV Scheduling, Server-Server, and Free/Busy URL between multiple dissimilar clients and servers. The majority of 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 morning. The Technical Committee sessions were organized sequentially, without competing parallel sessions, to allow all attendees who wished to be involved in the discussions of a Technical Committee the opportunity to do so.

Report on Roundtable X, September 19-21 2007

1. Update on Technical Committees and Initiatives

Work Products since Roundtable IX:

TC CALDAV has published CalDAV Scheduling Requirements.
TC MOBILE has published the Mobile Calendar Interoperability Test Suite.
The DST Ad Hoc Committee has published CalConnect EDST Reflections and Recommendations, reviewing how the industry dealt with the early DST conversions in March, and with recommendations both for the November 4 reversion from Daylight Savings Time, and for the future of DST and timezone management.

1.1. TC CALDAV

TC CALDAV reported on its work to date including its recently-published CalDAV Scheduling Requirements paper. Discussions covered new and continuing work in several areas of potential extensions to the CalDAV specification, including Roles, Access Control, Alarm Management and other scheduling extensions.

1.2. TC EVENTPUB

TC EVENTPUB reviewed the current state of the VVENUE proposal, generating a great deal of discussion concerning possible intersections between VVENUE and the potential work on vCard. The TC also reviewed the current status of work on the “eventmap” event sharing proposal.

1.3. TC FREEBUSY

TC FREEBUSY reviewed work since the last Roundtable, especially work on Free/Busy URL and in preparing for the Technology Previews of CalDAV Scheduling, serverserver, and Free/Busy URL. Going forward the TC will continue work on Free/Busy URL and on Free/Busy discussions with external entities.

1.4. TC IOPTEST

TC IOPTEST reported on the IOP test event just completed, and discussed early plans to implement an issue-tracking mechanism and to work with TC MOBILE on planning for a Mobile Interoperability Test Event.

1.5. TC MOBILE

TC MOBILE presented and reviewed its recently-published Mobile Calendar Interoperability Test Suite, and discussed plans for an initial Mobile Interoperability Test Event, including liaison activities with the OMA/DS group. The TC may also participate in establishing interoperability testing for vCard if the Consortium goes forward in this area, as vCard is already reflected in the Mobile IOP test suite.

1.6. TC REALTIME

TC REALTIME has been reactivated since Roundtable IX, and has been meeting alternately with TC FREEBUSY to work on the VAVAILABILITY proposal and the Technology Previews at this Roundtable. Going forward the TC will work on the REALTIME messaging protocol, Discovery, and Authentication and Authorization.

1.7. TC TIMEZONE

TC TIMEZONE was reactivated to consider the DST Ad Hoc recommendations and work on a formal Timezone Registry proposal and a proposal for a Timezone Service Protocol. The TC presented the conceptual work to date for the registry and service proposals.

1.8. TC USECASE

The TC presented its in-progress work on Resources generating a lengthy discussion on the subject. The TC has also undertaken a study of recurrence features in mobile device support for TC MOBILE.

1.9. Daylight Saving Time Ad Hoc

The DST Ad Hoc published CalConnect EDST Reflections and Recommendations just prior to this Roundtable, and gave a short discussion of the paper and its recommendations. The Ad Hoc will remain instantiated until it is apparent whether additional information gathering and delivery will be needed in preparation for the November 4 reversion to standard time.

The Consortium plans to initiate a TC in the area of XML representation of iCalendar data; a draft charter will be prepared shortly after the Roundtable.
The Consortium will initiate a TC in the area of a vCard Revision if the resources can be found. A draft charter will be circulated via the public vcard-workshop-l mailing list.

2. Future Meetings

ROUNDTABLE XI: February 4-8, 2008, at Sun Microsystems, San Francisco Bay Area, California.

The format of the CalConnect week is:

Monday noon through Wednesday noon, C.I.T.E. (CalConnect Interoperability Test Event)
Wednesday noon through Friday noon, Roundtable (TC sessions, BOFs, networking, Plenary).
