[eGroupWare-developers] Relaunch of "calendar for sitemgr"

[Hans-Juergen T. <ta...@he...>]

Hi!

After I had my try with a calendar display module for the sitemgr (for
automated event publishing) with eGroupware 1.4, I'd like to start "from
scratch" for 1.6.

The problems with 1.4 were various, the core problem I faced was the
session management, which keeps some calendar data of the user in the
cache (but if I visit the website while logged in, I don't want to see
my personal calendar but the public announcements).

The new approach should be based on existing ical/caldav PHP calendar
viewers and use:
- one (or more) networking calendars
- from a defined user (default: The anonymous user)
- of a defined time scale (multi-week or month view)
- caching of the data found

Can someone (Ralph, you probably know the caldav code best :-) ) please
point me to a function any prerequisites in order to use internal
functionality to retrieve caldav (or ical) data instead of pulling the
data through the network - but with a fixed user ID?
What would be the URL of a remote calendar to limit view on user and
time frame?
Also, maybe, there is already a framework that can be used for the
caching mechanism?

Thanks a lot,
Hans-Jürgen
