How to have calendar events indexed by search engines

I'm developing a site for which one of the main components is an events calendar. For users, the calendar is offered in 3 formats

1. an interactive AJAX web calendar (monthly view)
2. an iCal subscription feed
3. a downloadable PDF

None of these seem particularly search-engine friendly. What would be the best way to make sure the individual events ar开发者_JS百科e being indexed?

My ideal situation is where, for example, a user would type into a search engine "[company name] craft fair" and land on the calendar page for November 2010 which is showing the fall craft fair event.

All events should be exposed as individual, seo optimized links and included in sitemap.

Request to this link should open specified item or whole calendar with selected item.
