Calendar database

The Maemo 5 calendar database can be found in /home/user/.calendar/calendardb. The goal of this article is to provide enough information on the calendar database in order to implement mass modifying/adding/deleting events verifying some criterias (string match in title, locations, comments for example). It could be easy then to write a small shell script using zenity and sqlite3 to perform this tasks.

If you want to help editing this article and writing useful informations on fields or new scripts, feel free to copy your own database on your computer and analyze it with some tools like "SQLite Database Browser" (Linux/Debian). The datatypes are those listed in the SQLite documentation.
