Application Development Software

Hello,

I use a java application that can synchronise external  events from iCal file (google calendar for exemple). I would ask,

If  Oracle convergence provides iCal file for all user events? Or we have only caldav protocal?

With caldav protocal can i make filters (start date, end date, ..)  in my request to "base_url/dav/home/adress@mail.com/calendar/"?

Thanks.
