Seems that I need to set some kind of calendar alarm to remind me to post here!
I haven't heard any new news on the Calconnect.org front, although there was another Interop in early June, so there's nothing to report there.
There is, however, some new news as far as uses of iCalendar goes.
I regularly attend SHARE, which is a conference of computer users. SHARE started as a group of IBM users 50(!) years ago in 1955. They are now a group of IBM users, but users of anything which runs IBM software. The conference happens twice a year, and the sessions at SHARE run the gamut from Windows desktops to "giant" (actually smaller than some server racks) z/990 machines.
Like many other groups, SHARE tries to have conference agendas online to make it easier to plan your attendance. Well, starting with the next conference, their 105th, each session will have a calendar link attached to it, which allows you to dowload and open an iCalendar file! This, of course, lets you add the sessions directly to your calendar, if your calendar package supports iCalendar. It works in Outlook - I tested it at home even though I don't use Outlook for my home calendar. It won't, of course, work in Palm Desktop - because its VERSION component is "2.0" and Palm Desktop doesn't support that "new-fangled" iCalendar, they just support vCalendar. It may work in Apple's iCal but I don't have one to test with.
At any rate, this is great news - now we will be able to build our own personal agendas and sync them to our PDAs (if we have them). If you've ever tried to keep track of what sessions you want to attend for a large conference like SHARE, you'll realize what a boon this is.
