Do you mean that:
CONSTRUCT
{
?obj :result ( "A prefix" ?value1 ?value2 ?value3 ) .
} .
Works only when all values are present? It's Wrong...
The method that concatenates the prefix and values should ignore blank
and non-existent values and let the WHERE clause define what comes and
what doesn't.
Have you tried:
CONSTRUCT
{
?obj1 :result ?value1 .
?obj2 :result ?value2 .
?obj3 :result ?value3 .
} .
I know the result is not what you want, just to see how those engines
are rendering the query.
