At #ldow2010 on Tuesday there was a presentation on "semantic" Twitter 
via TwitLogic:
http://twitlogic.fortytwo.net/

You can download the full paper if you're really curious:

Twitter Annotations system was mentioned at the end as a possible side 
option. There's bound to be a good bit of talk in the Linked Data 
community on strapping RDF/RDFa into Twitter Annotations, but I believe 
that's still beginning.

Additionally (as someone outside of the library community proper), 
OpenURL's dependence on resolvers would be the largest concern. Anyone 
could build similar "real thing" URL's and use 303 See Other redirects 
to return one or more digital resources about that "real thing." See 
this for more information:

Enjoy the reads,
