Re: calendar file for IETF
Bill, I couldn't agree with you more regarding multiple overlapping events. They're all designed for the case where one might double-book, and even on occasion triple book, but 8 or 9 events? None of them deal with that correctly. I could go on and on about what these Calendar programs don't do, but as I'm not going to fix them...

updated calendar file for IETF
Same location: http://www.ofcourseimright.com/~lear/ietf63.ics This one has the following changes: - proper quoting (RFC 2445). - published agendas are now included - URLs to WG Charters are now included - several schedule changes - room numbers are now included Again, use at own risk. This calendar does not merge 1 hour meetings. If you want that, see Bill Fenner's message to the IETF discussion list. Similarly so if your calendar program barfs on timezones.

Absolutely... Be that as it may, I was intrigued as to why Thunderbird did such a different job on the two files. A quick look at the code did not help. Anyway thanks for the effort.. very useful!

Re: calendar file for IETF
Why would you want to have a calender without timezones?? Mostly for clients with bad user interfaces - e.g., old Apple iCal which didn't let you set the display time zone differently from the system time zone, or web-based calendar servers that don't allow the visitor to set the display time zone.

Actually, the client I'm working on does do a pretty good job of laying out the events in IETF meetings. The reason for that is that I actually used the IETF meeting schedule as an example of a complex schedule that had to be displayed properly, and designed the system so that the IETF meetings look nice when displayed. The algorithm for doing that was of course designed to be generic enough to handle other complex schedules too. -- Cyrus Daboo ___ Ietf mailing list Ietf@ietf.org https://www1.ietf.org/mailman/listinfo/ietf

Outlook is unable to parse the VTIMEZONE object generated by iCal - despite the fact it conforms to 2445. What's alternately amusing and horrifying is the VTIMEZONE object's I've seen that Outlook can process are pretty goofy. For one thing the Outlook/Exchange-generated VTIMEZONE object uses a start date of Jan 1, 1601. This is hilarious. There are other problems with the iCalendar files generated by Microsoft, and with Outlook's attempts to read iCalendar files generated by means other than Outlook/Exchange.

Re: calendar file for IETF
It reads in to Thunderbird OK, but the result is less pretty than Eliot's effort. Eliot's version appears to lay out the multiple events in a partcular timeslot evenly across the available space, whereas Bill's results in different sized blocks and in some cases some of the events appear to be hiding others. Looking at the .ics sources it is not obvious why this should be. Clearly Bill's has additional useul info... need a merge of the two!

Since I'm not going to be in Paris, but do want to listen in to some sessions, having proper timezone info in the ics would allow me to see the times adjusted to my own local timezone without having to do any math in my head!

This may be because mine treats two sequential 1-hour meetings as a 2-hour meeting, and Eliot's treats them as 2 1-hour meetings. See l3vpn on Monday and mip6 on Tuesday evening. I originally wrote the agenda parser that's the basis of this .ics output when we switched to 1-hour meetings on Tuesdays because I could never tell whether a given meeting was one or 2 hours long. I have yet to find a client that has a good variable-length overlapping event rendering algorithm, especially with 8-9 events in the overlap. Apple's iCal usually does really well when there are 3 or 4. Bill ___ Ietf mailing list Ietf@ietf.org https://www1.ietf.org/mailman/listinfo/ietf

No responsibility if you miss your meetings. No promises to update it. But it works for me. Thanks for the file. Unfortunately it is not a valid iCalendar file as the VERSION property is missing. That property is required by the iCalendar specification (rfc2445 section 4.6). To fix this, just add the following line below the 'BEGIN:VCALENDAR' line: VERSION:2.0 In addition, each VEVENT component needs to have a UID property with a unique identifier in each one. Whilst the syntax of section 4.6.1 of rfc2446 implies that that parameter is optional, the description for the parameter itself (section 4.8.4.7) actually says it MUST be present. The Calisfy working group is attempting to fix ambiguities in the spec like that, amongst other things. I did 'fix' my version of the file with suitable changes and was able to import it correctly into my client. Also, I note there is a new updated agenda out that is different from the one you posted.
