RE: Vcal having multiple events and tasks

Hi,
 
 But isn't multi events and todos valid in a single vCal version 1.0?
 
The following grammer very much says that it is possible that we have many events and todos in a single vCal, please do comment on this?
 
And regarding iCal ( which i think is vCal version 2.0) is this grammer removed in iCal?
 
vcal     = “BEGIN” [ws] “:” [ws] “VCALENDAR” [ws] 1*CRLF
     calprop calentities [ws] *CRLF
     “END” [ws] “:” [ws] “VCALENDAR” [ws] 1*CRLF

 

calentities = calentities *CRLF calentity
     / calentity

 

calentity   = evententity
     / todoentity

 

evententity = “BEGIN” [ws] “:” [ws] “EVENT” [ws] 1*CRLF
     entprops [ws] *CRLF
     “END” [ws] “:” [ws] “EVENT” [ws] 1*CRLF

 

todoentity  = “BEGIN” [ws] “:” [ws] “TODO” [ws] 1*CRLF
     entprops [ws] *CRLF
                                “END” [ws] “:” [ws] “TODO” [ws] 1*CRLF

According to RFC 2445 multiple events within a vcal is not valid. Wether the entire vcal will be treated as corrupted or not is entirely depended on the parser. Like in my case i would parse all the events as valid or maybe thje first event. But if you stick to strict RFC 2445 then your vcal is invalid. Why do u want to do that. If are thinking of some proprietory solution why not roll out your own format in xml.
 
For more information go through the RFC 2445 documentation.
 
Do let me know.

Vcal having multiple events and tasks

Hi,
 
   I have simple question, regarding vCal 1.0
 
does it support multiple events and todos within a single vCal? If so is this object considered to be a valid one?
 
BEGIN:VCAL
 
BEGIN:VEVENT
END:VEVENT
 
BEGIN:VEVENT
END:VEVENT
 
BEGIN:VEVENT
END:VEVENT
 
Note that END:VCAL is not present.
 
Also what should be the behavior when a particular vEvent within the vCal is corrupt, should the entire vObject be treated as corrupted, or the decoder should just ignore the corrupted vEvent and process the others?
 
Please do give your feedback, if possible, also the link or document where i can find the specs for the same.
 
Thanks And Regards,
Vairavan.S

Reg TZ property of a vCal

Hi,
 
  I have a clarification regarding version 1.0 of vCal, vCal has properties like TZ and DAYLIGHT, and objects like vEvent and vToDo. Now based on the TZ and DAYLIGHT the time and date values of the event is converted normally. Here comes my doubt, is it possible that the TZ and DAYLIGHT property comes after the END:VEVENT, like the following,
 
BEGIN:VCAL
VERSION:1.0
BEGIN:VEVENT
...
...
...
END:VEVENT
TZ:+00:00
DAYLIGHT:FLASE
END:VCAL
 
is the above vCal a valid vCal?
 
Thanks And Regards,

RE: Reg Date and Time representation in vCal 1.0

Hi,
 
 But the vCal specs says, The date and time values for all vCalendar properties are formatted as a string consistent with the ISO 8601 representation for combinations of dates and times
 
and according to ISO 8601,
 

Combined Date/Time Formats

The symbol "T" is used to separate the date and time parts of the combined representation. This may be omitted by mutual consent of those interchanging data, if ambiguity can be avoided

Does it mean that an ideal decoder should be able to decode date and time both with T as a seperator and without T as a seperator?
 
Thanks And Regards,
Vairavan.S

I believe that notation is from an ISO standard and the T is quite mandatory.

Hi,

 

  I have a very genuine doubt regarding vCal 1.0 date and time representation, is it mandatory to represent the character 'T' between date and Time.

 

DTSTART:20061212T080808

 

 Is the t as a seperator mandatory or optional?

Few Questions Reg Vcal


 Hi,

  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?

  Regds,

   Manoj

 P.S. Kindly forgive me if any of above is naive, as am very recently
introduced to any PIM application.

Top 10 iCal clients & interoperability Tests


Hi, I want to know if anyone has done any marketing research on the top 10 
most popular iCal clients in the market?  I want to see if there is such a 
thing.

I know that MSN supports iCal protocol as well.  Do you know if other public 
providers are supporting that?

Do you know where I can get information or a consortium for doing an iCal 
RFC2445 interoperability Tests?

Thanks.
