[Ietf-calsify] embedding the iCalendar URI (a late proposal related to 2445bis)

[Julian Reschke]

Hi,

I've got a quick question about the iCalendar format, or actually an idea.

If I serve an iCalendar resource through HTTP, what I really want is to 
allow the client not only to read it (display it in a calendar 
application), but also to *subscribe* to it, for which I obviously need 
the URI.

Apple, years ago, "solved" this (and potentially some other use cases) 
with their custom "webcal" URI scheme. (I note that this URI scheme 
hasn't been registered with IANA.)

The Atom WG was smarter, by allowing the format to carry a "self" URI, 
for subscription (see 
<http://greenbytes.de/tech/webdav/rfc4287.html#rfc.section.4.2.7.2>).

Bernard already pointed me to the URL property 
(<http://tools.ietf.org/html/rfc2445#section-4.8.4.6>), but what I'm 
looking for is a Calendar property, not a Component property (I think).

Is something like that possible in iCalendar? If not, could/should it be 
added? (Separate document?)

BR, Julian
