Discussions during the current #IETF meeting led me to write a new draft on a compact CoAP URI expression, Short Paths In CoAP (ShoPinC, following the trade tradition of contrived acronyms).
As not all of the #CoAP crowd is reading the IETF lists, I'm soliciting opinions or feedback from here as well.…

Short Paths in CoAP

This document introduces an option that allows expressing well-known paths in as little as two bytes.
