Hi!
I am particularly looking forward to the tool that builds a query.. The examples as provided proved really important for me to start using these tools. I really hope for a similar service for the new service.
That's where community input/contribution is very welcome :)
The documentation is only about the test environment. It mentions Wikigrok. Does the implementation mean that it now runs on the live data...
https://www.mediawiki.org/wiki/Wikidata_query_service/User_Manual is about production environment.
It runs on live data, and the synchronization time is on https://query.wikidata.org/ (look for "Last updated").
There may be technical issues that make it fall behind from time to time (I know about them and am working to fix them) so it may be not up-to-the second synchronization yet. Ideally, that's what we're striving to reach, and that's what happens most of the time, but not 100% of the time _yet_.
