Bot operators are currently marking imported data from the Wikipedias with "imported from:Wikipedia X" as a reference/source for the claim.
This method has a strong opposition:
A more relevant information would be to show on which sites the statement value is being used, because:
a) it is roughly equivalent to "imported from", but always up-to-date
b) it gives a good overview of which sites are using which data
c) it switches the mindset from "unidirectional data imports" to "import data and use it"
A way to show this information could be with a section similar to "X sources" but called "X uses". On expansion, it would show which sites are using the value.
