[jena-arq] Cast a literal to an IRI

[Nicolas Paris <ni...@gmail.com>]

Hello,

Is there a way to cast a literal to an IRI within SPARQL in jena ?
(link to sparql 1.1 doc)
http://www.w3.org/TR/sparql11-query/#func-iri

eg: I have got triple:

foo bar "baz"^^anyUri
baz rdf:label "tiz"^^xsd:string

I would like to query  :

foo bar ?baz
IRI(?baz) rdf:label ?tiz

then i would like to get :

?tiz = "tiz"^^xsd:string

Thanks by advance,

Hello Andy,

Thanks a lot, this works as I wish.
It looks like I missed something in the doc.

BIND assigns function values to to new variables:

foo bar ?baz
BIND(IRI(str(?baz)) as ?baz_iri)
?baz_iri rdfs:label ?tiz
