A couple of months ago I began saving the iCalendar files that are submitted to the iCalendar Validator. Today I extracted a list of unique names of iCalendar producers along with associated counts of the number of calendars validated for each. Here they are, with Google Calendar at the head and a classic long tail distribution of almost 600 other iCalendar producers. (You can also see them elsewhere by name as well as by count.)

The next step will be to analyze how well these these producers conform to the validator’s interpretation of the iCalendar spec. But the list itself forms an interesting data set. We know intuitively that, after 12 years of evolution, the iCalendar ecosystem must have become broad and diverse. Here’s a nice illustration of that breadth and diversity.

(Note that these counts don’t necessarily reflect the real distribution of iCalendar producers. The iCalendar Validator is closely associated with the elmcity project, so certain producers used heavily there — DDay.iCal, EVDB, Meetup — are overrepresented. On the whole, though, I’d guess this is a reasonable proxy for the distribution of producers.)
