Hi Graham, I think you have to use exactly what you have, an array of bytes (i.e. byte[]). Here's a unit test in Jena for base64

How do I store that in a typed literal. I guess I need something like this model.add(subject, predicate, model.createTypedLiteral(bytes, new XSDbase64Binary("???"))); But what do I put in the ??? part? thanks graham
