I'm having a problem - probably a misunderstanding, possibly a bug - using Values.statement and .iri to insert data into stardog. I created a short example to try to figure out what I was doing wrong. I think it also illustrates my problem nicely:

```
aConn.begin();	
				final Statement aStatement = Values.statement(
						Values.iri("http://purl.org/rail/simulator/Test#testting")
						,Values.iri("rdf:type")
						,Values.iri("http://purl.org/rail/simulator/Test")
						,(Resource) Values.iri(URIs.BraveDataModelBase));
				aConn.add().statement( aStatement);
				final Statement idStatement = Values.statement(
						Values.iri("http://purl.org/rail/simulator/Test#testting")
						,Values.iri("rdf:id")
						,Values.literal("uniqueID")
						,(Resource) Values.iri(URIs.BraveDataModelBase));
				aConn.add().statement(idStatement);
		
		aConn.commit();

```

This produces the following RDF (exported from stardog):

```
<http://purl.org/rail/simulator/Test#testting> <rdf:type> <http://purl.org/rail/simulator/Test> ;
  <rdf:id> "uniqueID" .

```

As you might assume I was hoping for rdf:type and rdf:id NOT having "\<" and "\>" as if they are uri's.  
How should I be creating the triples?

You can get the rdf:type IRI directly from the `com.stardog.stark.vocabs.RDF` class. Otherwise, the prefix declaration isn't recognized in the string passed to `Values.iri()` so you must expand it and pass the full IRI.

Many thanks, how might I go about adding some prefixes (such as rdf)?

Prefixes are not recognized in these calls. You can do:

```auto
Values.iri("http://www.w3.org/1999/02/22-rdf-syntax-ns#", "type");

```

Or

```auto
Values.iri(com.stardog.stark.vocabs.RDF.NAMESPACE, "type");

```
