CalConnect Workshop on Tasks – Wednesday May 25, 2011

CalConnect will hold an open Workshop on Tasks on Wednesday afternoon, 25 May, at NASA Ames, Mountain View, California.


Over the last few years there have been more and more applications developed that allow users to manage tasks or to-do lists. In particular, with the ever increasing use of smart phones, there are now a plethora of smart phone “apps” that allow users to manage their task lists. Many of those offer an option to synchronize the task list with desktop computers or “the cloud”. However, in many cases a proprietary synchronization protocol is used with non-standard data formats.

Tasks (VTODOs) are a part of iCalendar and thus part of CalConnect’s focus. In 2007 our USECASE Technical Committee developed a use case document on tasks based on a review of existing products, with the goal of identifying commonality of properties and establishing a minimum set needed for interoperability.

Since that time the potential applicability of VTODOs has expanded into areas such as project management, and energy/price scheduling in the work being done towards the national “Smart Grid” effort, with a concomitant increase in needed properties and flexibility.

The aim of the CalConnect workshop is to examine the key use cases for tasks with the goal of promoting use of iCalendar and CalDAV as a standards-based solution to task management and synchronization. We expect that extensions to both iCalendar and CalDAV may be needed to support the key features that application developers require.

Proposed Agenda:

1. Introduction
2. Review of current task based applications and services
3. Introduction to tasks in iCalendar and CalDAV.
4. Examination of key use cases – where do iCalendar and CalDAV fall short?
5. Conclusions – what is needed to support a standards-based task management system, what can CalConnect do to help?

Who may participate:

Participation in the workshop is open to interested individuals, regardless of whether or not they work for CalConnect members, or are otherwise registered for the CalConnect Roundtable or interoperability test event. (Participants in the CalConnect Roundtable are automatically registered for the workshop.)

No fee will be charged for attending the workshop; however you will need to register in advance, and space is limited.


The meeting will be held in the NASA Ames Conference Center, 500 Severyns Road, NASA Ames Research Center, Moffett Field, Mountain View, California.

Non-U.S. Residents please note: NASA Ames is a government installation and there are some special restrictions on access to the NASA Ames Research Center. U.S. Citizens and permanent residents may gain access by presenting their driver’s license and (if not a U.S. citizen) green card. However, visitors to the U.S. who are not permanent residents will require an invitation from NASA which must be arranged well in advance. If you are planning to attend the workshop (or any part of CalConnect week) and have not already made these arrangements please contact us immediately at:


The workshop will be held from 1:30 to 4:00 Wednesday afternoon, May 25th, at the NASA Ames Conference Center, as the first item of business at the CalConnect Roundtable. There will be a break and refreshments from 4:00 to 4:30, followed by a presentation by NASA and an evening Reception. Workshop attendees are invited to stay for the NASA presentation and the following reception beginning at 5:30.

Four weeks to CalConnect XXI at NASA Ames

Only four weeks until CalConnect XXI, the week of May 23-27, 2011, at NASA Ames in Mountain View, California. If you are planning to come, you should get your registration done by May 6th as the early registration rate ends on that day, and registration will change from $350 to $395 for the Roundtable. We’re also going to be holding a workshop on Tasks on Wednesday afternoon the 25th, and of course our interoperability test event on Monday-Wednesday. You can find information about the week, including schedules, logistics, and registration information, at

Remember, you don’t have to be CalConnect members to attend the interoperability test event. And if you’re not members you can attend the Roundtable as observers. We’ll post more about the tasks workshop in the next day or two – it will be available to individuals not attending either the Roundtable or the IOP test event, subject to room and advance registration.

Microsoft announces Exchange ActiveSync Logo Program

For anyone who did not see the original announcement, on April 13th Microsoft announced EAS, its Exchange ActiveSync Logo Program: “to establish baseline for EAS functionality in mobile email devices . The program is designed for device manufacturers that license the EAS protocol from Microsoft for use in mobile email clients that connect to Exchange.” This includes a test plan which must be successfully demonstrated to qualify a device for the plan.

As ActiveSync is broadly implemented upon mobile devices, many of which support calendaring services, this is clearly of interest to those in the calendaring and scheduling space.

Microsoft is a member of CalConnect, and we have in the past conducted ActiveSync-based interoperability testing between multiple servers and devices using ActiveSync. While CalConnect is unlikely to figure as part of the EAS program, we expect that our interoperability testing and Mobile Calendaring Interoperability Test Suite will provide a useful adjunct to EAS participants in the futre in validating their complex calendaring interactions.

Registration is open for CalConnect XXI May 23-27 at NASA Ames Research Center

Registration is now open for CalConnect XXI, May 23-27, 2011, at NASA Ames Research Center, Moffett Field, Mountain View, California. Please see for logistics and registration information.

As usual, we will be conducting an Interoperability Test Event Monday-Wednesday, May 23-25. Information about the Test Event is at The Roundtable Members’ Meeting will be Wednesday-Friday May 25-27.

We will be conducting a Workshop on Tasks on Wednesday afternoon during the Roundtable from 1:30 to 3:30. This workshop is open to non-CalConnect members, and you do not have to register for the Roundtable to attend; however you do need to register for the workshop. See the logistics page noted above for more information. NASA will also offer a tour of the Ames Rsearch Center on Friday afternoon following the close of our meeting.

The meeting venue is at the NASA Ames Conference Center, 500 Severyns Avenue, located in the NASA Ames Research Center on Moffett Field. The logistics page includes a map of the area (including the location of the meeting venue and hotel).

Note well: NASA Ames is a government installation and has security controls. If you are a U.S. citizen you must show your driver’s license or proof of identify If you are a non-citizen permanent resident you will need to show a driver’s license or passport and your “green card”). If you are a non-citizen visitor, you will need a special invitation from NASA and visitor pass; see the logistics page for more details.

The Conference Hotel will be the Sheraton Sunnyvale, which is very close to NASA Ames. They are offering a discounted rate for our conference. This is a courtesy rate and we do not have a room block, so you should book early to ensure you get the special rate. We have a special booking arrangement so be sure to review the Hotel section of the logistics page carefully.

We will be announcing additional and special sessions of interest as more material becomes available. We expect to set the actual schedule for TC sessions by mid-month and announce the topical agendas early in May.
