Just to note, that is a BIBFRAME1 vocab example. You can tell because the namespace is http://bibframe.org/vocab...
You could certainly extract them and post them to their own end points, but you have to decide how to make the uris unique in your endpoint area: Karen's had a unique uri for the Work: http://id/test/C:\Users\deborah\Documents\OxygenXMLDeveloper\samples14107665 , but nothing for the Instance. If she wanted, she could have posted the Work part to http://kcoyle.net/bibframe/works/samples1410665 And she could have posted the Instance part to http://kcoyle.net/bibframe/instances/samples1410665 (and changed the bf:Instance bf:instanceOf address to the new work URI). <bf:instanceOf rdf:resource="http://kcoyle.net/bibframe/works/samples1410665 "/> BY the way, the bf2 version is comparable here (if I'm right that the number is the LC voyager bib id): Id.loc.gov/tools/bibframe/compare-id/full-rdf?find=14107665 or Id.loc.gov/tools/bibframe/compare-id/full-ttlf?find=14107665 It's also available for extraction and use here: http://lx2.loc.gov:210/LCDB?query=rec.id=14107665&recordSchema=bibframe2a&maximumRecords=1 Making things even more interesting, this one also has embedded Work descriptions : <bf:Work rdf:about="http://bibframe.example.org/14107665#Work740-46"; > <rdfs:label >Blest pair of sirens.</rdfs:label> They are pretty skimpy but could be used as stub descriptions and given their own identity (uri) until such time as they can be reconciled to an existing description or be more fully cataloged to stand on their own.

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?
