Ok, thanks for the information. I didn't realize that it is good to start with owl:Thing as the root. And using Turtle is a good idea. I am just used to seeing many different foaf files that have everyone represented inside a <foaf:Person> </foaf:Person> set of tags. My file now has me inside a Description tag which doesn't appear in Turtle format. Anyway, I did something wrong with the mbox tag. Or maybe not. The spec says it is a owl:Thing but I don't have the value for it. Then there is the isuse of foaf:depiction which I had been just using rdf:resource="http://path/to/photo.jpg."; Anyway, this is what I have in Turtle with regard to not knowing where or how to specify the email: :BruceWhealtonJr a foaf:Person ; rdfs:label "Bruce whealton jr"^^xsd:string ; skos:prefLabel "Bruce whealton jr"^^xsd:string ; foaf:birthday "2011-07-24"^^xsd:date ; foaf:gender "male"^^xsd:string ; foaf:mbox [ a owl:Thing ] .
Oh, one other thing, if I had foaf:interest and used both a rdf:resource which points to a url and dc:title which is a text attribute, this isn't going to be part of the FOAF spec is it? So, in N3, I have <http://whealton.info/BruceWhealtonJr/foar.rdf#me>; foaf:interest <http://dbpedia.org/resource/RDF>, and then I have <http://dbpedia.org/resource/RDF> dc:title "RDF". in this case it is actually shorter in RDF/XML because I have <foaf:interest rdf:resource="http://dbpedia.org/resource/RDF"; dc:title="RDF"/> My question is how do I do that in TBC? Do I need to create a blank node and if so how? Or just like foaf:depiction the value or range should be a URL but it isn't letting me do that. Maybe because I'm entering it as a property and not an instance value.
