rq turtle/ttl

does work in like 4 seconds. 10:41, 8 August 2019 (UTC) pagetalk / TomT0m author This is basically the same query except its used in a named subquery that is just included as is in a parent subquery. I don’t really understand why this timeout in that setup. This also fails with a regular subquery :

Use at

PREFIX schema: <http://schema.org/>
select ?item ?article ?titre

{
    {
    select ?item ?article ?titre {
      ?article schema:about ?item ;
               schema:isPartOf <https://fr.wikipedia.org/> ;
               schema:name ?titre .
               filter not exists { ?item schema:description ?descr filter (lang(?descr) = "fr") }.
    } limit 10
            }
  ?article schema:about ?item .
} limit 100
