Per @jkeck, the live lookup code is not straightforward ... and moreover, may be in javascript. Our RDF sourced data is using the default catalog_controller code and thus probably isn't even triggering the javascript live lookup methods at all. Plus, unclear if the live lookup code for our marc records is easy to use for a different record display.
Jessie thinks if we went with live lookup, we might be better off creating an appropriate RDF display type (akin to Mods and Marc behaviors in SearchWorks code) and going from there.
AKA: seriously non-trivial.
Some of the above implies this route is likely non-trivial as well.
Given a ckey, how feasible is it for the RDF data to
