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_.
this is great news! How is it kept up-to-date? Do you generate and load
incremental updates?
