iCalendar Validation

In my previous post, I spoke about Jon Udell's work with iCalendar feeds and his push toward acceptance and compatibility of iCalendar feeds on the Internet. With electronic scheduling and calendaring become a more popular method to manage ones life, the ability to share this information with others also becomes increasingly necessary.

In response to this problem, Jon Udell, Ben Fortuna (creator of iCal4J), and I have started an initiative to standardize the iCalendar validation process, to ensure that calendars indeed will work with any system that consumes them:

We've also begun work on an XML schema for representing information that validation utilities can use to validate iCalendars. This validation process will notify the end user about variations from the standard, and will indicate areas of their iCalendar that may be incompatible with other systems, along with recommending alternatives.

If you're interested in validation of iCalendars, then please visit the Wiki.

Thanks,

iCalendar feeds

Hi everyone,

Jon Udell from Microsoft has been doing some interesting work lately involving iCalendar feeds, their current status, and where they need to go for future acceptance.

Among the libraries he's using to test are:

• iCal4J
• DDay.iCal
• iCalendar.py
• vObject
