Jo, Given that XMLSchema dates (ISO8601) are the basis for most WWW date and time, I would venture a guess that it has been a direct help to anyone reading this message. And should you know of anyone looking at grant funding for Time OWL, kindly send them my way. A lot of people are desperate for a better "people time" solution and Time OWL is currently the only such solution. I use it.
To paraphrase a colleague "The nice thing about standards is that there are so many of them to choose from" (See also [1]) . This said for all of the many problems with WGS84 (aka EPSG:4326), it is not a stretch to say that it currently runs a big chunk of civilization. I am not a fan of GML or KML, but a number of javascript libraries will draw on the screen in some reasonable way if you give them a string in that standard. GML is also the only spec that I have seen deal with precision and accuracy. This is a problem for me in the automated extraction of features and I insist it be something that OHM should tackle, probably not with GML. Whatever solution we come up with will also be useful in automating some of the 2D rendering decisions that are currently hard-coded. Jerry's routing over historical data is a nice prototype and foreshadows cool applications with historical simulations of say, the barbarians sacking Rome or railroad goods distributions in Victorian England. But It's a prototype. Not a tool yet or a major piece of infrastructure that everyone is going to pound on. What makes that prototyping possible is that the 'core' tools have been solid and consistent enough for others to build around them. This thread is a necessary exercise to get us to that same point.
