IETF releases "Requirements for a Location-by-Reference Mechanism"

The Internet Engineering Task Force (IETF) released Requirements for a Location-by-Reference Mechanism, or RFC 5808. Place, or unambiguous identification of location, can get complicated quickly, especially when things like security and context come creeping into the equation.

Being able to identify a place in space and time in a (mostly) context free form seems to be of value to me. If I leave my Namiki M90 in my desk at the office, I can ascribe several locations descriptions to it: where I left it, in my drawer, at the office, etc. It's actual location could be used equally well to describe other things: where I left it, my drawer, the office, etc. Time is important, too, since I am prone to pick it up, move it around, write letters, etc. Also, what if an earthquake shifts my desk 3 meters to the West Southwest? What about reuse? Expiry? Confidentiality? Interesting stuff!
