[Historic] the "spherical mercator" of time?

[Mikel Maron]

One thing I'm pondering is how to efficiently and easily share time aware geodata. Prior to Google gifting the world spherical mercator tiles, web maps were rendered on request, based bounding box, dimensions, projection. WMS was slow. Naturally I'd expect we'd use cached tiles for serving time data, but I don't see an obvious way of this not exploding to all arbitrary times in history. Perhaps enough to begin by expanding the tile template to /{time}/{zoom}/{x}/{y}, and maybe limiting time to year or decade or century. Is there something more clever? What ways do historians bring methodical order to the times and eras in history that are of most common interest and utility?
