I have a small appeal to you, my dear readers. I seem to recall that there was, in the not-too-distant past, an RDF-based concept that - I think - went by the name of "Personal Flight Plan" (though it doesn't show up on Google). If, by chance, I have dreamt it, then I naturally take all of the kudos.
The idea was to store a sequence of geographic locations for a person, to represent the tour that he or she had made of the world hitherto, complete with naturally-rich metadata. There was, I believe, a little Flash animation that would render this path on a map of the world.
I've been writing quite a bit about the places that I've been visiting in recent weeks, and it would please me to bring all of this information together in a useful (by which I mean machine-readable, not practically useful), structured form. As with most SemWeb things, I'm sure there would be interesting applications that one could build upon it, as well.
Right now, I don't really have the ability to do anything with this, beyond writing down my itinerary, but I'd love to build an application to support it. It would be quite simple, providing a way to create these files, and render them, using a zoomable map. I've no idea if this would be practical or not, but I'd enjoy the exercise.
So, if anyone remembers the original website, I'd greatly appreciate a pointer, or any other suggestion, in the comments.
