I posted this last week to wikidata@lists.wikimedia.org, but perhaps this is a better forum for this problem. Re-posting it here.

Federated queries are disabled on the stand-alone code out-of-the-box.

I followed the advice on this post to un-disable federated queries for my local installation: 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 is also the case when addressing a Jena service I have set up on a different port.

I would appreciate any guidance you could give me.

Thanks and regards,
