Anyone an idea why this query has a trouble when I add the OPTIONAL keyword?
Doesn't look much harder than the queries in the examples.
Looking at the bottom of the exceptions, you can see that the system simply refuses to run the query. The problem seems to be with the labelling service. If you don't select the label for ?head, it works fine:
It seems the implementation of the label service needs some improvement to support unbound variables (which should then return unbound labels, rather than throw a runtime exception ;-).

However, you would miss people like me, who use the service mainly from within R or my text editor (Text mate with turtle bundle). I wouldn't see a blinking banner.

Fair enough. A big blinking banner at the top of the page might do then? Cheers Lydia -- Lydia Pintscher - http://about.me/lydia.pintscher Product Manager for Wikidata Wikimedia Deutschland e.V.
