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.

You can use the <noscript> tag to provide this information to search engines and users that have disabled javascript in a textual format.

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.
