Few Questions Reg Vcal/iCal

[Manoj Gangadhar Dixit <mgd@xxxxxxxxxx>]

 Hi,

Kindly forgive me if any of below is naive, as I am very recently
introduced to any PIM application. Basically I wanted to know the basic 
difference between vCal 1.0 and iCal. Also wanted to know which is more 
popular vCal 1.0 or iCal? 

  I have Few questions :

  1. I would like to know where I can find this document:
     XAPIA CSA, Calendaring and Scheduling Application Programming
     Interface (CSA) Version 1.0, X.400 API Association, November 15,
     1994.
     This document is being reffered in Vcalender Spec 1.0. I tried google
     but unable to get it.

  2. Is this the major difference between Val 1.0 And iCal?
     a. Reg Object Specification :
        iCal specifies "object Methods" and using iTIP scheduling protocol
        defines transport independent ways of exchaning schduling
        information with messages like PUBLISH, REQUEST, ADD etc.
        Such a transport independent specification is NOT available with
        vCal (1.0).
     b. If "a" above holds then how the PIM application (possibly from
        different vendors) implementing Vcal 1.0 interact (in absense of
        any Protocol) with each other?

  3. Any freeware giving PIM Calendar Source code?
  4. Is there any spec reqd apart from RFC2445/2446/2447 to implement 
     iCal?


  Regds,

   Manoj
