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 ;-).

Hi Denny,
The following R script

wikidata content on a worldmap in R.

Is there a write up of how you are using Wikidata from R? That
sounds quite cool.

I think a blinking banner would work on the main side.
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.

Hi!
Yes it is the continuation of the beta on labs.
Stas: Do you want to turn that into a redirect now?
Not sure yet what to do with it. I want to keep the labs setup for
continued development work, especially when potentially breaking things,
but we do want to redirect most of the people now to main endpoint as it
is much better at handling the load.
Fair enough. A big blinking banner at the top of the
page might do then?
Cheers
Lydia
