Hi all,
I'm Adrian Bielefeldt an writing on behalf of Research:Understanding
Wikidata Queries
<https://meta.wikimedia.org/wiki/Research:Understanding_Wikidata_Queries>,
a research project aimed at gaining an insight into the way the query
service <https://query.wikidata.org/> of wikidata is being used. We have
some questions and are wondering if any of you could provide us with an
answer.
1. Is there a unique key for the query log? The log I am refering to is
the *wdqs_extract* table**from the hive database wmf.**We would like to
be able to permanently link our own computed data with the log entry we
computed it from.
2. Is it possible to find out if a query in a given log entry was
accepted by the sparql endpoint as valid?
3. Is there any other database system besides hive installed on the server?
And finally a question on conventions for this mailing list: Am I
correct in sending one mail for multiple questions or should I send
separate mails for each question?
Greetings,
Adrian Bielefeldt
