Re: PROPOSED WORK ITEM: DID-Linked Resources Specification

Given DWNs only rely on a few parameters to be able to identify a resource
in this way (schema URI, protocol URI, Record ID, and Context ID [I don't
mean JSON-LD context]), it would be great to see these as params that can
be normalized at whatever layer so we don't have to 1:1 replicate them
through the adjacent service-specific query syntax. If it ends up that the
param set of this desired initiative was inclusive of a param set that we
could use in DWN query URLs, then that would certainly lower the ol' blood
pressure a lot.
