Let's say I have this simple model for a dataset of books
<a-book>
title "only 1 title" .
topic "some topic", "another topic", "many topics" .There is one title, but several topics. I want to retrieve a list of books, together with their title and only one topic (any one of them is OK). So what I want is a list of results like this <book-1> title "title" <book-1> topic "some topic" <book-2> title "the title" <book-2> topic "random topic" ... Is there any (simple) way to do this with SPARQL?
