Hello, Is it possible to do a report on a collection of calendars, like a user’s calendar home? If I’m looking for an event by UID, I can find it in a specific calendar with a report like this: <?xml version="1.0" encoding="utf-8" ?> <C:calendar-query xmlns:D="DAV:" xmlns:C="urn:ietf:params:xml:ns:caldav"> <D:prop> <C:calendar-data/> <D:getetag/> </D:prop> <C:filter> <C:comp-filter name="VCALENDAR"> <C:comp-filter name="VEVENT"> <C:prop-filter name="UID"> <C:text-match>F3CFFF98-555B-4961-BF6E-7BDAA75AAEF3</C:text-match> </C:prop-filter> </C:comp-filter> </C:comp-filter> </C:filter> </C:calendar-query> But, if I’m not sure which calendar it’s in, I want to run the report on the user’s collection of calendars. I’m not a CalDAV expert, but I did find section 7.2 of the CalDAV RFC:

Servers MAY support the reports defined in this document on ordinary collections (collections that are not calendar collections), in addition to calendar collections or calendar object resources. In computing responses to the reports on ordinary collections, servers MUST only consider calendar object resources contained in calendar collections that are targeted by the REPORT request, based on the value of the Depth request header.

This seems to suggest that a server may support this kind of report, but when I ran it (with Depth: infinity) I got an empty <multistatus/> back. Any ideas? Sidney San Martin: Developer | DeepTech, Inc. sidney@deeptechinc.com | T: 646-638-4824
