Hi Joshua, not sure if I understood you correctly, but I think you are asking two questions:
First, how to resolve URI as http://www.unprot.org/uniprot/Q6GZX4 to data served at http://www.unprot.org/uniprot/Q6GZX4.rdf? The regexuri LDCache endpoint was introduced exactly for those cases where servers are not fully Linked Data friendly. The second is how to trigger the caching of those references resources? In the Marmotta KiWi stack LDCache is triggered every time a triple-pattern like "<uri> ?p ?o" is requested from the triple store. Then LDCache tries to load URI from remote according the available configuration. That remains completely valid for raw Linked Data requests, LDP requests and LDPath queries, but not anymore for SPARQL. Because performance reasons the new SPARQL implementation by-passes the Sesame stack, so queries are directly issued to the database. That means that if you want to used the cached data for SPARQL queries it'd need to be cached before. A trick we commonly use is to force the cache triggering by sending a simple LDPath program that matches with the resources you want to cache eagerly. In you case, whatever statement you use lo link with those IDs. If our users community remains asking about such eager population, we might need to think about an infrastructure to directly support it. Hope that helps.
