As a Wikibase evaluator, I want to make SPARQL queries of my local Wikibase using federated properties so that I can combine and reuse data in the Wikibase.
The test system should have a Query Service (0.3.32) so that querying can be tested/verified by the PM during the development of the federated properties feature.
We should do this in such a way to also help facilitate easier creation of additional test instances (with a Query Service) that can be used in user testing (T255419).

The Query Service has been installed on the Federated Properties test system at https://query-federated-properties.wmflabs.org. It is running the docker image 0.3.40, which has been newly created per T250974. The following example query returns three results, one 'Berlin' item from the Federated Properties test system UNIONised with two 'Berlin' items from wikidata.org:
PREFIX fpwdt: <http://wikidata.beta.wmflabs.org/prop/direct/>
PREFIX wdt: <http://www.wikidata.org/prop/direct/>
SELECT ?item ?ISNI
WHERE
{
VALUES ?ISNI {"0000 0001 1364 8293"}
{
SELECT ?item ?ISNI
WHERE
{
?item fpwdt:P253125 ?ISNI;
}
}
UNION
{
SERVICE <https://query.wikidata.org/sparql> {
?item wdt:P213 ?ISNI;
}
}
}The WDQS has been added using ansible automation per T257213, which can easily be re-used to set up additional instances for user testing.
