Stephen,

I've looked at Karen Coyle's examples in the past. They are extremely
helpful for figuring out how to structure the BIBFRAME record, but my
question is more about how the BIBFRAME model interfaces with the semantic
web as a whole. As you mentioned, Karen's examples, like the LC examples
Nate mentioned, have both Work and Instance objects at the top level. To my
(limited) understanding, that makes them suitable for ingestion into a
local system for indexing but not necessarily as URI endpoints. For
example, if I were to reference http://kcoyle.net/bibframe/sr.rdf.xml in
another RDF document, how would an application know if I am referencing the
Work or the Instance?
