Access to Linked Data

Get the clear idea about the linked data; come up with suggestions.

very up-to-date

so up to date that nothing will support it :) but a nice and parsable alternative…

I've implemented RDF support in 42e9daf (in a new lod branch) and created a very basic example in c773060:

@Override
public Model encodeRDF(User t, MediaType mt) {
    Model model = ModelFactory.createDefaultModel();
    URI uri = getUriInfo().getBaseUriBuilder()
            .path(RootResource.class)
            .path(RootResource.USERS)
            .path(UsersResource.USER).build(t.getName());
    model.createResource(uri.toASCIIString())
            .addProperty(VCARD.EMAIL, t.getMail())
            .addProperty(VCARD.NICKNAME, t.getName());
    return model;
}

It will result in this RDF output (I've implemented RDF/XML and Turtle encodings):

curl http://localhost:8080/webapp/rest/users/testuser1 -H "accept: application/rdf+xml"

<rdf:RDF
    xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"
    xmlns:vcard="http://www.w3.org/2001/vcard-rdf/3.0#">
  <rdf:Description rdf:about="http://localhost:8080/webapp/rest/users/testuser1">
    <vcard:NICKNAME>testuser1</vcard:NICKNAME>
    <vcard:EMAIL>testuser1@example.org</vcard:EMAIL>
  </rdf:Description>
</rdf:RDF>

curl http://localhost:8080/webapp/rest/users/testuser1 -H "accept: text/turtle"

<http://localhost:8080/webapp/rest/users/testuser1>
        <http://www.w3.org/2001/vcard-rdf/3.0#EMAIL>
                "testuser1@example.org" ;
        <http://www.w3.org/2001/vcard-rdf/3.0#NICKNAME>
                "testuser1" .

Closed because the task is to unspecific.
