[Tdwg-guid] Jena examples?

[peter.hollas at thomson.com]

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.
