ok... a little shower always help, now i understand your remark :)
The thing is, this first module is retrieving '_data' from another app.
This other app is not written to share '_data' with other apps.

So my first module should be the only one which deals with types checking because those data will then be available to
my app from a DB (... once i've written the second module :)
