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.
The procedures used to develop this document and those intended for its further maintenance are described in the CalConnect Directives.
In particular the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the CalConnect Directives.

This document was prepared by Technical Committee CALCONNECT.
CalConnect XLII took place June 4-8, 2018, hosted by Jorte in Tokyo, Japan. The Developers Forum (Monday, Tuesday, and Wednesday morning), Data Event Summit with JEDC (the Japan Data Event Committee) (Wednesday afternoon), and Conference (late Wednesday afternoon, Thursday and Friday) were held at Jorte’s offices in Tokyo or in conference rooms in the same building.
The CalConnect Conference was attended by a total of 12 people from 8 members. The Developers Forum had 7 participants from 4 members and was largely devoted to the forum rather than specific testing. The Conference focussed on strategic and possible work items in addition to ongoing work, and finished with the CalConnect Plenary Session on Friday afternoon. The Conference agenda with notes on the discussion topics may be found at CalConnect XLII Conference Schedule.
The Data Event Summit was attended by a total of 26 people, all CalConnect participants for the conference plus 15 people from JEDC, and featured presentations from two government agencies, Sharp, and our hosts. The primary focus was Japan’s efforts to ensure open data is available from their local governments (about 1800) in a common data format, and our encouragement for them to adopt the international calendaring and scheduling standards, which would require some enhancements and joint work between us.
Much of the ongoing work in CalConnect is focused on specifications and standards, many of which will become internet draft submissions to the IETF and ultimately be progressed to publication as RFCs (Proposed Standards), rather than directly published by CalConnect itself. CalConnect will also co-publish standards with other standards organizations, or self-publish as needed.
Specifications in progress and not yet published are generally resident on GitHub either in our public or private areas.

CalConnect has established a formal reciprocal membership liaison with M3AAWG.
CalConnect has established formal Category A Liaisons with the folllowing ISO Committees:
ISO PC 317
ISO TC 154
ISO TC 211
ISO TC 46
ISO JTC 1 SC 27
ISO TC 37
IETF is considering reopening the TZDIST working group to deal with the new Time Zone drafts we have submitted.
A new TC CALSPAM has been created to work on calendar spam best practices, a joint effort with M3AAWG, and is actively working on a best practices document. The work has been at both the latest M3AAWG conference and our Tokyo conference.
A new TC STREAMING has been created from the Ad Hoc previously set up. Its first task will be the devleopment of the specification.
TC IOPTEST was closed as its function has been subsumed into the Event Planning committee and process.
CalConnect is planning to resume its practice of self-publishing standards, which hasn’t been done for some time as much of its work has focused on extensions to existing IETF specifications (many of which were also developed by CalConnect). A new Ad Hoc on Publishing has been set up to review the obsolete processes and establish new ones. CalConnect also intends to begin co-publishing some documents with other organizations with which we have liaisons.
The TC CHAIRS committee has been renamed the Technical Coordination Commitee to better reflect the role and responsibilities of this group.
A new work area has been proposed on “Party Crashing” — event invitations can be forwarded to uninvited persons who then can spoof the the systems to gain an invitation.
The work on CALSPAM has proposed a new work item on establishing a mechanism whereby users can determine where an event on their calendar came from.
More discussion was held on a proposal for a completely revised conference format for CalConnect, which would offer both the Conference Track and a Technical Track as a single event with a single fee. This matter is being proposed for a one-time test at the next (Karlsruhe) event.
Status provided on synchronization (time to draft a spec?), server-side subscriptions, series as an alternative to recurrences.
Work on JSCalendar is progressing, accommodating contacts and tasks as well as events.
Pending; Draft update in progress
Response tokens for Party Crashing (NWI proposal from Google)
CALSPAM’s proposal for storing information about how events ended up in iCalendar.
Review approach on standards
Move page content from Drupal to DevGuide where appropriate
Looking into GitHub pages (layout first, CNAME second)
Draft has been submitted to the IETF; we are exploring which working group should handle it. Looking for more implementations.
