Virtuoso R2RML rr:IRI generating - mapping

Question

I have a problem with generating rr:termType rr:IRI in Virtuoso. I don't know if am I doing it wrong but I followed the W3C specification.
My mapping looks like this. When I generate triples with CONSTRUCT statement I still get "URL" but not IRI => <url> (OWNER_LINK and BRAND_LINK columns). Is it something Virtuoso doesn't support or am I coding it the wrong way?

Answer 1

So I figured out my code was wrong it should be like this
rr:predicateObjectMap
[
rr:predicateMap
[
rr:constant s:url
];
rr:objectMap
[
rr:termType rr:IRI ;
rr:template "{BRAND_LINK}" ;
];
];.
and it's working
Thank you.

Answer 2

To be clear — are you saying the R2RML mapping is loading successfully, but when running a SPARQL CONSTRUCT query, the rr:termType rr:IRI mapping is not being displayed in the result set?
As the docs indicate, only rr:sqlQuery is not currently supported ...
