<< vCalendar defines a transport and platform-independent format for exchanging calendaring and scheduling information in an easy, automated, and consistent manner. >>
-> vCalendar est un format d'échange
<< iCalendar consists of three RFCs:
* RFC 2445, Internet Calendaring and Scheduling Core Object Specification (iCalendar)
* RFC 2446, iCalendar Transport-Independent Interoperability Protocol (iTIP): Scheduling Events, BusyTime, To-dos and Journal Entries
* RFC 2447, iCalendar Message-based Interoperability Protocol (iMIP) >>
--> iCalendar est une série de spécifications ? A confirmer, c'est vrai que c'est très mal documenté.
