Very important point with which I agree - it is completely possible that update polling misses an update, WDQS is no exception and it usually does not treat it as a problem, as the next update can fill up the missed one. However the ultimate truth source is on the wikidata site only. Beware of the caches though - if you ask for the same data on the same URL twice, I think you can get the same result even if the underlying data changed in the meantime. -- Stas Malyshev [email protected] _______________________________________________ Wikidata mailing list [email protected] https://lists.wikimedia.org/mailman/listinfo/wikidata
