'DerivedCoreProperties.txt" is in 'native-inputs',
so you need to do (assoc-ref (or native-inputs inputs) (string-append "data/" i))
to make sure it will be found when cross-compiling.

(When compiling natively, 'inputs' is merged into 'native-inputs')

Alternatively, you could move "DerivedCoreProperties.txt"
to 'inputs'. It isn't something that is compiled, so it
doesn't really matter if it is in 'inputs' or 'native-inputs',
except for ‘style’ I
suppose.
