#Wikidata several people are adding information about former and present Members of the European Parliament. In the "Mix-n-Match" tool we link information from the European Parliament to Wikidata and, by inference to many Wikimedia projects.
It involves identifying people who were also an MeP. Often items can be merged when multiple articles exist for the same person or Wikidata does not know a person was a MeP.
What is surprising is that the demise of Mr Caillavet is not known on the website of the European Parliament. Linking data will make it easier for them and for us to know about such things in a more timely manner.
