That's great! Thanks a lot.
By the way,
https://www.wikidata.org/wiki/Wikidata:SPARQL_tutorial#FILTER that try
to do FILTER(STRSTARTS(?humanLabel, "Mr. ")). the first one is broken
but I assume it used to work.
This is not working because there's not :
FILTER(LANG(?label) = "en").
As it's explained later in the example apparently.
Thanks again!

so that's trying to filter the given name item not the label of the

there's a few examples at
https://www.wikidata.org/wiki/Wikidata:SPARQL_tutorial#FILTER that try
to do FILTER(STRSTARTS(?humanLabel, "Mr. ")). the first one is broken
but I assume it used to work.
adapt the second "Mr. " example there and I get:
SELECT DISTINCT ?person ?personLabel ?givenNameLabel ?gnlabel WHERE {
?person wdt:P31 wd:Q5.
?person wdt:P735 ?givenName.
?givenName rdfs:label ?gnlabel.
FILTER(LANG(?gnlabel) = "[AUTO_LANGUAGE]").
FILTER(STRSTARTS(?gnlabel, "A"))
SERVICE wikibase:label { bd:serviceParam wikibase:language
"[AUTO_LANGUAGE],en". }
}
that times out even with LIMIT 5. but if I test with a smaller dataset
(fictional humans) it appears to be written properly:
SELECT DISTINCT ?person ?personLabel ?givenNameLabel ?gnlabel WHERE {
?person wdt:P31 wd:Q15632617.
?person wdt:P735 ?givenName.
?givenName rdfs:label ?gnlabel.
FILTER(LANG(?gnlabel) = "[AUTO_LANGUAGE]").
FILTER(STRSTARTS(?gnlabel, "A"))
SERVICE wikibase:label { bd:serviceParam wikibase:language
"[AUTO_LANGUAGE],en". }
}
