Hi Everyone, Does anyone have/or know of any good examples of using Jena to output RDF metadata with non-typical namespaces such as TCS/RDF? Currently I have the following code for my metadata method(I know it's wrong!). String TN_NS = "http://tdwg.org/2006/03/12/TaxonNames/"; ByteArrayOutputStream byteStream = new ByteArrayOutputStream(); Model model = ModelFactory.createDefaultModel(); Resource res = model.createResource("http://test"); res.addProperty(model.createProperty(TN_NS,"testProperty"),"test"); model.write(byteStream, "RDF/XML-ABBREV"); return new MetadataResponse(new ByteArrayInputStream(byteStream.toByteArray()),null,MetadataResponse.RDF _FORMAT); ...which gives me. <rdf:RDF xmlns:j.0="http://tdwg.org/2006/03/12/TaxonNames/" xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"> <rdf:Description rdf:about="http://test"> <j.0:testProperty >test</j.0:testProperty> </rdf:Description> </rdf:RDF> ...whereas I could really do with something along the lines of the IPNI metadata. <rdf:RDF xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:dc="http://purl.org/dc/elements/1.1/" xmlns:dcterms="http://purl.org/dc/terms/" xmlns:tn="http://tdwg.org/2006/03/12/TaxonNames/" xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"> <!-- example family (has an unlinked typifying name with non-standard format data)--> <tn:TaxonName rdf:about="urn:lsid:ipni.org:names:30000959-2:1.1.2.1"> <tn:nomenclaturalCode rdf:resource="&tn;#botanical" /> <dc:title>Amaryllidaceae J.St.-Hil.</dc:title> <dcterms:created>2004-01-20 00:00:00.0</dcterms:created> <dcterms:modified>2005-06-23 15:45:33.0</dcterms:modified> <tn:rankString>fam.</tn:rankString> <tn:nameComplete>Amaryllidaceae</tn:nameComplete> <tn:uninomial>Amaryllidaceae</tn:uninomial> <tn:authorship>J.St.-Hil.</tn:authorship> <tn:publishedIn>Expos. Fam. Nat. 1: 134. 1805 [Feb-Apr 1805]</tn:publishedIn> <tn:year>1805</tn:year> <tn:typifiedBy> <tn:NomenclaturalType> <dc:title>Amaryllis Linnaeus, nom. cons.</dc:title> </tn:NomenclaturalType> </tn:typifiedBy> </tn:TaxonName> I think the main problem I have is creating resources that aren't defined as vocabularies within Jena already. I can't seem to find a way to create that <tn:TaxonName root resource element. I'm starting to think that just outputting vanilla text could be the best option here, or am I barking up the wrong tree? Many thanks, Peter.
