This proposal involves setting up an IANA registry to hold the controlled vocabulary of the SP category container. The registry would be setup with an open registration policy and might hold both URIs and abbreviated names (to support protocols with payload constraints of some form). The boiler-plate text could be copied from draft-johansson-loa-registry. Setting up an IANA registry involves:

  1. writing an I-D describing the registry
  2. getting a shepherd (eg an AD) for the individual publication process
  3. going through RFC publication

This is not a short process and in order to keep our March deadline we would have to start using the URI of the container before getting it published.
