RDF and N3 format examples?

[markfarrell]

What should the response look like when rdf or n3 are selected as formats in a request?

[rwarren2]

See the redland library bindings. You are better off to create the content in memory and then serialize it out to the web server - at least for the headers.

Using redland/librdf. Are these responses correct?

N-triples example:

<rdf:Description rdf:nodeID= should be <rdf:Description rdf:about= but that might be a parser problem.
