In that case, isn't the object of rdf:resource an identifier (URI), and not a URL? foaf has homepage, which has range document... but these aren't homepages, just any sites with some unspecified relationship to the person. > To be honest, maybe I don't know the 2nd draft RDF example (I *just* > joined the list, etc., etc.).

No, I don't have access (yet) to a dev machine, so I can't move in any changes. I have to send them along to Anand, and they aren't live yet. I posted a mocked-up API output that looks like: <?xml version="1.0" encoding="utf-8"?> <rdf:RDF xmlns:rdf='http://www.w3.org/1999/02/22-rdf-syntax-ns#' xmlns:rdfs='http://www.w3.org/2000/01/rdf-schema#' xmlns:rdg2='http://RDVocab.info/elementsG2/' xmlns:dcterms='http://purl.org/dc/terms/' xmlns:foaf='http://xmlns.com/foaf/0.1/' xmlns:ol='http://openlibrary.org/type/author#' > <rdf:Description rdf:about="http://openlibrary.org/authors/OL22022A";> <foaf:PersonalProfileDocument rdf:about="http://openlibrary.org$author.key";> <dcterms:modified rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime>2010-06-03 01:02:45.525432</dcterms:modified> </foaf:PersonalProfileDocument> <foaf:Person> <foaf:name>Barbara Cartland</foaf:name> <rdg2:variantNameForThePerson>Mary Barbara Hamilton Cartland</rdg2:variantNameForThePerson> <rdg2:biographicalInformation>Dame Mary Barbara Hamilton Cartland was an English author, known for her numerous romance novels. She also became one of the United Kingdom's most popular media personalities, appearing often at public events and on television, dressed in her trademark pink and discoursing on love, health and social issues. Other than her fictional romance books, she also wrote health and cookery books, and stage plays and recorded an album of love songs. She was often billed as the Queen of Romance.</rdg2:biographicalInformation> <rdg2:dateOfBirth>9 July 1901</rdg2:dateOfBirth> <rdg2:dateOfDeath>21 May 2000</rdg2:dateOfDeath> <rdg2:titleOfThePerson>Dame</rdg2:titleOfThePerson> <rdg2:identifierForThePerson>http://openlibrary.org/authors/OL22022A</rdg2:identifierForThePerson> </foaf:Person> <ol:link> <foaf:primaryTopic rdf:about="http://openlibrary.org/authors/OL22022A"; /> <ol:uri>http://en.wikipedia.org/wiki/Barbara_Cartland</ol:uri> <ol:title>Wikipedia</ol:title> </ol:link> <ol:link> <foaf:primaryTopic rdf:about="http://openlibrary.org/authors/OL22022A"; /> <ol:uri>http://en.wikipedia.org/wiki/List_of_books_by_Barbara_Cartland</ol:uri> <ol:title>Wikipedia entry</ol:title> </ol:link> </rdf:Description> </rdf:RDF> > > I attached the ProvenanceStatement mainly because it seems > <http://openlibrary.org/authors/OL31800A> is about Margaret Mahy and > modified/created/revision/etc. is about the metadata about Margaret > Mahy, not Margaret Mahy herself. Interesting: I used foaf:PersonalProfileDocument, which I interpreted to be a reference to the metadata itself (but I could be wrong). Is this a standard format for referring to a metadata record?: http://openlibrary.org/authors/OL31800A#meta It would be great to have a common way to express that. > > I just changed rdagr2:identifierForThePerson to dcterms:identifier > there because we know she's a person (at this point, thanks to the > foaf:Person type) and dcterms is a much more recognized vocabulary > than RDA Group 2. DC less specific, but the RDA G2 one is probably overkill anyway. I'll switch that to dcterms.
