Hi, While going through the caldav specifications I understood that data exchange in the protocol in done using iCalender format. So it is really necessary to accommodate iCalender format in the project if we are going to support caldav protocol. But working with two data formats for calender events would e really painful. So it is really good if we can change the current data model to support iCalender data format.
So the first question I had was whether I have to change the data model of the project (regarding the appointments table and other tables relevant the event data in the project) so that it can store the iCalender objects in the database. Unless I am not going to change the datamodel, I have to map the current columns in the data tables to the matching fields in the iCalender objects (which would not be practical sometimes. But with this method, adding the functionality of recurrence events support wont take much effort as the the we can easily store recurrence details in the current appointments table). Somehow the first part of the project would be to convert the existing calender events format to iCalender format. After doing that I have start working with adding the missing iCalender and caldav functionality to the project. Please correct me if I am wrong.
