Hi Karen, Here's the RDF I got back from the link you gave:
@prefix rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#> . @prefix rdfs: <http://www.w3.org/2000/01/rdf-schema#> . @prefix bibo: <http://purl.org/ontology/bibo/> . @prefix rdg2: <http://RDVocab.info/elementsG2/> . @prefix dcterms: <http://purl.org/dc/terms/> . <http://openlibrary.org/authors/OL31800A> rdg2:biographicalInformation """Margaret Mahy ONZ (born i....""" ; rdg2:dateOfBirth "21 March 1936" ; rdg2:identifierForThePerson "/authors/OL31800A" ; rdg2:name "Margaret Mahy" ; rdg2:variantNameForThePerson "Mahy, Margaret" ; dcterms:modified "2010-04-12 12:42:10.448987" ; bibo:uri "http://en.wikipedia.org/wiki/Margaret_Mahy"; . I'd like to understand if you're modelling this as a person, or as a "bibliographic entity" as obviously that has implications. Putting aside the possible confusion of pen-names my preference would be to see the author modelled as a person, or an organisation if a corporate author. This should be shown as a type statement so we know which way OL goes. <http://openlibrary.org/authors/OL31800A> a foaf:Person ; If using foaf Person, it might be better to foaf:name for the name, foaf doesn't include a variant name so you might need to invent that, or where possible you could parse the name into family and given using the foaf properties. I know, names are a can of worms. Having made Margaret a Person, it then wouldn't be right to say that she was modified! You'd have to add in some data about the representation or dataset. <http://openlibrary.org/authors/OL31800A.rdf> dcterms:modified "2010-04-12 12:42:10.448987" ; dcterms:subject <http://openlibrary.org/authors/OL31800A> . That date would ideally be typed as well, so we can do date sorting: <http://openlibrary.org/authors/OL31800A.rdf> dcterms:modified "2010-04-12 12:42:10.448987"^^xsd:Date ; It would also be good for the date of birth to be formatted and typed as an xsd:Date: <http://openlibrary.org/authors/OL31800A.rdf> rdg2:dateOfBirth "1936-03-21"^^xsd:Date ; A further implication of making Margaret a Person is that you can't use bibo:uri, bibo says that things with a uri are either a Document or a Collection, and those are not compatible with also being a Person. Also, uri probably isn't the right term to describe the 'aboutness' of a page. I did think foaf had topicOf, but I can't see it in the spec - but something like <http://openlibrary.org/authors/OL31800A> foaf:topicOf <http://en.wikipedia.org/wiki/Margaret_Mahy> Note, the uri is treated as a resource in RDF so goes in <> rather than quotes. I'm not sure what you mean by: rdg2:identifierForThePerson "/authors/OL31800A" ; isn't the full uri <http://openlibrary.org/authors/OL31800A> the identifier for the person? If you do want to model the OL identifier for use in non-uri based systems perhaps then you would also want the scheme the identifier came from, to do that the identifier might need to be modelled separately: <http://openlibrary.org/authors/OL31800A> rdg2:identifierForThePerson <http://openlibrary.org/authors/OL31800A#id> . <http://openlibrary.org/authors/OL31800A#id> rdf:value "/authors/OL31800A" ; rdg2:identifierScheme <http://openlibrary.org/identifier-scheme> . but I haven't thought that through very thoroughly. rob On 3 Jun 2010, at 16:54, Karen Coyle wrote: > There's a first draft of author RDF available.
