Very nice!

It's interesting that the sort-order in the subquery is preserved by the GROUP_CONCAT. (So eg this query works: http://tinyurl.com/yafz8zvn)

I'm not sure that the SPARQL standard guarantees this, indeed I thought I could remember @Lucas_Werkmeister_WMDE complaining that there seemed to be no way to ensure it. But it does indeed appear to work, so many thanks @Fnielsen for showing this is how it can be done.

Here's a very slightly tweaked version of @Fnielsen 's query -- this time workplaces of society portrait painter Philip de Laszlo, showing points as well as lines: http://tinyurl.com/ydev3fjs
