what client(s) should be targeted in implementing an ICalendar export for events?

Question

http://en.wikipedia.org/wiki/ICalendar

I'm working to implement an export feature for events. The link above lists tons of clients that support the ICalendar standard, but the "three big ones" I can see are Apple's iCal, Microsoft's Outlook, and Google's Gmail.

I'm starting to get the feeling that each of these client implement different parts of the "standard", and I'm unsure of what pieces of information we should be trying to export from the application so that someone can put it on their calendar (especially around recurrence).

For example, from what I understand Outlook doesn't support hourly recurrence.

Could any of you provide guidance of the "happy medium" here from a features implementation standpoint?

Secondary question, if we decide to cut features from the export (such as hourly recurrence) because it isn't supported in Outlook, should we support it in the application as well? (it is a general purpose event scheduling application, with no business specific use in mind...so we really are looking for the happy medium).

Thanks,

Ian

Answer 1

I use iCal in Lightning (Thunderbird) and Rainlendar.

I have used Calendaring software for years (decades) and have never had a need for repeating events within the same day. It is simple to add additional daily repeating events in the same day if it is really needed.

Answer 2

I have to say that I don't use the hourly recurrence feature as really how many people have events that repeat in the same day? I could see if someone however was to schedule when they needed to take a particular medicine at recurring times throughout the day.

I would say support full features in the application itself, but provide a warning when they go to export the calendar that all event details may not work as expected or find a way to export in a different manner for Outlook alone that does provide the hourly recurrence feature.
