CalConnect XXXVI took place on April 18-22, 2016, hosted by Ribose and OGCIO in Hong Kong, as part of a larger event, the Hong Kong 2016 ITFEST. In addition to our regular conference and test event, we held a seminar at Hong Kong University, and a Public Day at the Hong Kong Convention Center on Wednesday. The CalConnect Test Event (Monday and Tuesday) and Conference (Thursday and Friday) were held at the Cyberport, about 20 minutes from central Hong Kong.
The CalConnect Conference was attended by 22 people from 15 members, plus 7 observers. The Test Event was held on April 18-19, 2016, and had 13 participants from 9 members, plus 2 observers.
The Conference focussed on strategic and possible work items more than ongoing work, in accordance with our new format, and finished with the CalConnect Plenary Session on Friday afternoon. The Conference agenda with notes on the discussion topics may be found at CalConnect XXXVI Conference Schedule.
Report on CalConnect Conference XXXVI, April 21-22, 2016
1. Status of documents since last conference
Much of the ongoing work in CalConnect is focused on specifications to become internet draft submissions to the IEETF and ultimately be progressed to publication as RFCs (Proposed Standards), rather than directly published by CalConnect itself.
1.1. Published Documents
Report on CalConnect Conference XXXV in Palo Alto, California
Report on Interoperability Test Event XXXV
1.2. CalConnect Specifications Published as RFCs
RFC 7808 Time Zone Data Distribution Service
RFC 7809 CalDAV: Time Zones By Reference
1.3. CalConnect Drafts completed IETF WG Last Call
New Properties for iCalendar
Calendar Availability (VAVAILABILITY)
1.4. New and Updated CalConnect Drafts at the IETF
v-event URI: A URI scheme for events
WebDAV User Notifications
WebDAV Resource Sharing
CalCOnnect Calendar Sharing
2. Technical Committee Work and Initiatives Going Forward
2.1. TC API
Working on a new key/value based data model. Much of the work is done and the remainder will continue.
2.2. TC AUTODISCOVERY
Will be reactivated to consider authorization issues.
2.3. TC CALDAV
Created initial draft of STRUCTURED-DATA iCalendar property — allows schema-based data to be included with an event/task
Created rough draft for scoped attendee parameters — allows control of which parameter(s) are sent in scheduling messages — initial draft in progress
Working on iCalendar-based patch/diff format — initial draft in progress
2.4. TC DEVGUIDE
Basic content for a single event is complete along with some other material. DEVGUIDE has been styled to fit with he CalConnect web site in appearance.
2.5. TC EVENTPUB
Reviewed DMOZ directory service as source of categorization but it doesn’t provide all the needed info. Will continue with editing approach of providing a web service to search and retrieve categories, but not invent something ourselves.
2.6. TC FREEBUSY
2.7. TC FSC
To be merged into TC SHARING.
2.8. TC IMIP
Investigating how/why particular MIME formats are used by vendors, in particular application/ics content-type.
2.9. TC IOPTEST
Conducted Interoperability Testing at CalConnect XXXVI. Looking at rebranding the test event as Developer’s Forum.
2.10. TC ISCHEDULE
Dormant. Specification is essentially complete but pending on other specs at the IETF which have a higher priority.
2.11. TC PUSH
Draft to be published to the IETF after CalConnect XXXVI.
2.12. TC RESOURCE
2.13. TC SHARING
Specifications completed over the last few weeks. Need to get some implementations and do some testing. New CalDAV tester tests would help. TC-Sharing will take on the work of coming up with a subscription model. How to upgrade subscriptions to something more efficient than periodic polling of an ics file.
2.14. TC TASKS
2.15. TC TIMEZONE
RFCs 7808 and 7809 published. Closed by decision of CalConnect Plenary XXXVI.
3. Special Events
On Tuesday evening, CalConnect offered a 2-hour seminar at Hong Kong University. On Wednesday, CalConnect held an all-day Public Day as part of the Hong Kong 2016 ITFEST, at the Hong Kong Convention Centre. More about these events may be found at Public Day and Seminar.
4. Plenary Decisions
Developer’s Guide announcement to be done after How to Contribute and Introduction sections added
Rebrand Interoperability Test Event as Developer’s Forum to reflect model of both testing and in-depth technical discussions
Close TC TIMEZONE
Provisional Committees PC QR (QRCODE include vCard info) and PC SEC (Security and Encryption) established, to report out at CalConnect XXXVII
TC AUTODISCOVERY will be reactivated
5. Future Events
CalConnect XXXVII: September 12-16, 2016 — dmfs, Dresden, Germany
CalConnect XXXVIII: February 13-17, 2017 — University of California, Irvine, California
CalConnect XXXIX: May 2017 — Tandem, Seattle, Washington
