Libxcal
From Arnout Engelen
The de facto standard for exchanging calendaring information is the iCalendar standard. This is a rather old-fashioned, plaintext file format. An slightly more convenient XML counterpart has been defined, dubbed xCalendar.
At the time of writing, there were no good actively maintained iCalendar parsing and manipulating libraries available.
At some point I had the idea of writing a library for reading, writing an manipulating calendars, which would support reading and writing both xCalendar and iCalendar. That would allow for easy convertion between the two. Some early code was written, but the project has since been abandoned.
