This is my first post.  gee, for a semantic web group, these archives are pretty hard to search. Appologies if this is posted incorrectly, please point me to somewhere else if need be. I'm wanting to experiment with a site that uses semantically marked up travel itinerary data.  Has a standard been developed for this yet?  hcalender seems like the logical choice without developing a new standard.  Each destination reached would be a new hcalender event? A long trip would be a list of hcalender entries.  each entry would need a new "vevent" id... That doesn't sound too bad but I'd like to conform to any standards or healthy precedents that exist. thanks!
