Hi, 

I have problem to create typed literal (datetime) when I use TripleJena.java class to add extra properties to aggreagation.

 AggregatedResource ar = agg.createAggregatedResource(new URI(resurl));

Triple triple =  new TripleJena ();

    triple.initialise(new URI(resurl));

    Predicate pred = new Predicate();

    UUID a = UUID.randomUUID (  ) ; 

    String blanc ="urn:uuid:" + a.toString();

     pred.setURI(new URI("http://www.mementoweb.org/terms/tb/validOver"));

    triple.relate(pred, new URI(blanc ));

    Triple tr =  new TripleJena ();

    tr.initialise(new URI(blanc));

    ar.addTriple(tr);  

    Triple trd =  new TripleJena ();

    trd.initialise(new URI(blanc));

    Predicate pr= new Predicate();

    pr.setURI(new URI("http://www.mementoweb.org/terms/tb/start"));

    

    trd.relate(pr,(Date) date);

    ar.addTriple(trd);

The  literal type  is always String. How to  solve this problem?

Thank you, Lyudmila
