[Pellet-users] SPARQL results

[Ibach, Brandon L]

Jan,

I don't believe applying the "regex" function directly to a subject (a
URI/IRI) will work in SPARQL.  You probably just need to use the
built-in SPARQL function "str" to convert it to a string, first.  See
the example in the SPARQL recommendation (which is official, as of
today!).
