New subject: Wordnet mappings

      I followed the advice on this post: 
https://lists.wikimedia.org/pipermail/wikidata/2016-March/008444.html
(Thanks Mr. Malyshev!)
I did have one problem with the build: I found myself having to remove 
the checkstyle plugin from the pom.xml file to get the maven build to go 
to completion.
Now on my local installation I can get this query to work just fine:
(Current namespace: wdq)
Select *
Where
{
   Service http://localhost:9999/bigdata/namespace/test/sparql
   {
     Bind ("Algeria"@en as ?countryLabel)
   }
}
Also this:
(current namespace: test)
prefix rdfs: http://www.w3.org/2000/01/rdf-schema#
Select *
Where
{
   Service http://localhost:9999/bigdata/namespace/wdq/sparql
   {
     Bind ("Algeria"@en as ?countryLabel)
     ?country rdfs:label ?countryLabel.
   }
}
But this query (and every variation I could think of) unfortunately 
times out:
(current namespace: wdq)
prefix rdfs: http://www.w3.org/2000/01/rdf-schema#
Select *
Where
{
   {
     Select ?countryLabel
     {
       Service http://localhost:9999/bigdata/namespace/test/sparql
       {
         Bind ("Algeria"@en as ?countryLabel)
       }
     }
   }
   ?country rdfs:label ?countryLabel.
}
This also holds when addressing a Jena service I have set up on a 
different port.
I would appreciate any help. Also, is this question better posed to the 
WD tech list?
Thanks,
