Amir Ladsgroup has developed reports that show differences between the date of birth and the date of death as known in the English Wikipedia and Wikidata.
Such differences may be wrong in either Wikidata or Wikipedia. They are the ones that need attention, they are the ones where sources makes a real difference.
At this stage Amir is finalising the code. Given that this software can run repeatedly, the results will change when the software l earns about changes in either Wikidata or Wikipedia.
One practical question is where should these reports be located. It can be in both Wikipedia and Wikidata. It is likely that many similar reports reporting on different statements will become available.
