using ical to import and export would be a bit hard.

I need to syncronize each night from a XML file I have. The translation from the XML isn't a problem, but I thought of using the default pical classes and methods to insert the data, and manipulate it, or inserting them directly in the DB.

Is there any documentation on the structure of the database (what is expected, what is needed...), or is there some "API", which states how you should create and use the classes?

Something along the lines of:

$foo = new PiCal();
$foo->createEvent(some, data, here, like, the, title, and, timing ...);

or simular... an Api, or how I should manipulate the db...

Thx,
