It's a damn good start, though.

Thanks for the further info on the SRU check against viaf. I wondered 
why I wasn't seeing anything for dcterms:creator in the representation 
at all, and your explanation makes perfect sense. Very cool re: pulling 
additional URIs from LC and making the foaf:made assertions on them. 
I'll have to check that out when viaf comes back online.

I completely agree about the perils of lacking a persistence layer. 
Almost seems like it would make sense to cache remotely hosted data in a 
local triplestore, though that's the tradeoff when building all this 
stuff dynamically on-the-fly. Back to those discussions about caching 
and proxying for when a service goes down or is taken offline.

Thanks again for the very cool proof-of-concept, though!
