I'm cc-ing Erik Bernhardson who might have more experience with this data,
but we're all on break until the new year, so you may not get a response
until next week.

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
