This section defines the reports that CalDAV servers MUST support on calendar collections and calendar object resources.

CalDAV servers MUST advertise support for these reports on all calendar collections and calendar object resources with the DAV: supported-report-set property, defined in Section 3.1.5 of [RFC3253]. CalDAV servers MAY also advertise support for these reports on ordinary collections.

Some of these reports allow calendar data (from possibly multiple resources) to be returned.

Need to test your iCalendar feeds? The iCalendar Validator provides developers and testers a method to validate their iCalendar feeds, which can take data from either a URL, file or text snippet and compare it against the RFC 5545 specification.  We believe we have one of the best iCalendar validation tools available on the internet. More information about the validator can be found here.
