Works for me.
No database "TDB"
tdbupdate --loc TDB --verbose --debug --update=U.ru
tdbdump --loc TDB.
32903 quads.

This is what I tried :

--update=taxref-alignments.upd.rq
Where file taxref-alignments.upd.rq contains :
.ru
but it works anyway.

Result : the *TDB is not changed*; there are warnings that does not seems
important:

I checked by several queries that TDB is not changed:
SELECT * WHERE { GRAPH ?G {
?S ?P <http://taxref.mnhn.fr/lod/taxon/29388/13.0> .
} } LIMIT 100
It is a subject in the database.
<http://taxref.mnhn.fr/lod/taxon/29388/13.0> ?P ?O .
SELECT * WHERE { GRAPH <urn:alignments:taxref>
{?S ?P ?O . } } LIMIT 100
works for me.
How could I debug this, not knowing whether Jena or Wikidata server is at
fault ?
NOTE 1 : the corresponding, also federated, query gives results:
prefix wdtn: <http://www.wikidata.org/prop/direct-normalized/>
SELECT *
WHERE {
SERVICE <https://query.wikidata.org/sparql> {
?TAXON_WKDT wdtn:P3186 ?TAXON_TAXREF .
}
} LIMIT 44
when run by:
~/apps/apache-jena-3.16.0/bin/rsparql --debug --verbose --service=
http://localhost:9000/sparql --query taxref-alignments.rq
Not rsparql.
sparql.
You have sent the qhowl queyr to wikidata, not the SERVICE and LIMIT wil
be done there.
where localhost is semantic_forms server (Jena based) ;
or by:
~/apps/apache-jena-3.16.0/bin/rsparql --debug --verbose --service=
https://query.wikidata.org/sparql --query taxref-alignments.rq
NOTE 2: I also tried with a more ordinary graph ( fictitious ) URI : <
http://alignments.taxref.org>
