I would support adopting this specification.  The notion of var-base could be very helpful in many scenarios.  I have run into cases in OpenAPI where being able attach a globally unique identifier to a URI parameter would be extremely helpful.

I think this could significantly improve the usability of standardized rel values.  It would be nice to be able to communicate things like this:

Link-Template: <https://www.bing.com/search?q={search}> ; rel=”search”; var-base=”https://bing.com/searchparams/”

I also wonder if we could increate applicability by adding support for default values.  E.g.


Link-Template: </messages?skip={skip}&top={top}>; rel="next"; var-base=”https://odata.org/queryparameters”; defaults=(skip=100,top=30)

This would give a combination of a fully resolved URL and a uri template.

Mark. Should we put this on the agenda for IETF 112?
