11. Standards Efforts zIETF working group (CALSCH) charted to develop standards for calendaring and scheduling. It is tasked to: Create standards that make calendaring and scheduling software significantly more useful Develop standards that enable different products to interoperate and to work across organizational boundaries

12. Documents (Drafts & RFCs) zGuide to Internet Calendaring (currently in last call) zInternet Calendaring and Scheduling Core Object Specification (iCalendar) – RFC2445 (in interop testing) ziCalendar Transport-Independent Interoperability Protocol (iTIP) – RFC2446 (in interop testing)

13. Documents (Drafts & RFCs) ziCalendar Message-Based Interoperability Protocol (iMIP) – RFC2447 (in interop testing) zCalendar Access Protocol (CAP) ziCalendar in XML (new draft)

14. Examples zA doctor’s office wishes to keep track of all appointments – no standard required zA patient wishes to request an appointment with the doctor yThe patient’s calendar app uses iCalendar to define the grammar, iTIP to build the calendar object and iMIP to send it via . iTIP can check available timeslots and return them via iMIP

15. Examples zThe office wants patients to check timeslots first and the doctor wants to be able to look at his calendar from out of town yCAP allows software to check available timeslots with no delay and return available times – a CAP-enabled service or ISP can “present” the calendar to the doctor (similar to a POP server)

16. Putting it all Together

17. Summary zHeld three interop testing sessions yLotus, Steltor and iPlanet key vendors -Microsoft involved early on. Looking at 1 year before able to state iCalendar is a tested standard zInhibitors to draft/standard continuation yNeed more input from user community – all work done on mailing lists. Mailing lists can be intimidating to non- vendor members yCurrently, Microsoft “not” a key player

18. Summary zUser community usage will drive requirements for standards – calendaring not quite at the level of or Web usage zhttp://Calsch.org – resource for calendaring & scheduling

19. Q & A zHit “14” on phone pad to get in message queue
