@mnot has been working on collecting ideas for an update to RFC 5988 for 
a while now. maybe that's one more motivation to go forward with this? 
i'd certainly be willing to put in some time to get it off the ground.

this is not really code, but people want to use URI templates and there 
have been some efforts to provide a context that makes that more easy:

- @mnot's https://tools.ietf.org/html/draft-nottingham-link-hint

- my own https://tools.ietf.org/html/draft-wilde-link-desc

- part of the JSON home model: 
https://tools.ietf.org/html/draft-nottingham-json-home#section-3.1

if i recall correctly all of these have slightly different use cases and 
models, but (unsurprisingly) also a lot of overlap. it would be great to 
consolidate all of this so that tooling and implementations can rely on 
a robust spec.

cheers,

dret.
