W3C has a list of upcoming appearances. It's now (Mar 2003) available in .ics and RSS.

Once a week or so, some agent of mine (me being a team member) should check to see if there are upcoming appearances in my calendar that aren't in the list, or vice versa.

W3C has a list of upcoming events (mostly WG meetings). Each WG maintains a meeting schedule. Check that they're in sync once a week or so.

Check dependencies between WG meetings. Automatically raise issues on coordination group agendas.

I (TimBL) just (2005-02-04T05:31Z) tried again to use delta.py to sync calendars. This implements DiffAndPatch to provide a set of diffs between two RDF files, and works best when most nodes either have URIs or can be indircetly nailed to another node by a FunctionalProperty (FP) or InverseFunctioalProperty (FP). Those aren't wiki names, they are OWL classes. Anyway, for the record, the problems I had were:

  • The calendar properties are not noted as IFPs and FPs in the ontology.
 No big deal - I made a list of them.
 delta.py takes a --meta=foo.n3
 for stuff like that.  Request: put them in the ontology, please.
  • Alarms are a problem, as they don't have IDs. Evolution puts
 X-EVOLUTION-AlarmIDs
 on OWTTE, we noticed.  Removed all alarms to get around that.
 One event can have two identical alarms, and different people can
 change them at teh same time in a sync situation.
 Request: Add alarm IDs to iCal.
  • The timezone information in real iCalendar files has all kinds of
 conflicting
 stuff about real timezones. Removed all timezone info -- its on the web anyway.
 Request: resolve modus operani - does the tx ino on the net rule,
 or should we keep and keep consistent random daytime dates being  
 shipped aound in different iCal files?
  • iCal seems to have completely regenerated the UIDs for the events
 every time it saved back the file.  This last is a problem I was not
 execting, as I can't imagine how it keeps track of responses to an
 invitation if it keeps changing the UID.  Maybe this is a facet
 of the way we distribute .ics files with CVS.
 At this point I gave up!
