what does this mean? How do you access your data right now if not via
SPARQL? I mean you put it into a triple store or not?
Something like
select * where {
?s a madsrdf:PersonalName ;
text:query "some_search_string_here"
}
Also, as Andy pointed out, your index creation seems odd. You add an
index on madsrdf:elementList predicate, but according to your sample
data this doesn't link to string literals at all. It should be
madsrdf:authoritativeLabel in your config file
