This has also been aired in other discussions. Outdated entries can both be something that is only valid within a set timeframe, but can also be dependent on something else. One special case is when an external source do not support a specific statement anymore.

Hi,
regarding an actual topic in Germany about publication of the timetable-data of Deutsche Bahn (German national railway company) and their willingness of a discussion with other Open-Data-Supporters it may be a good idea of providing an expiration dates for Wikidata-records.
In their open letter to Mr. Kreil [1] they announced that it may cause problems providing the timetable-data in an open way if e.g. anybody uses old data.
