This basically means there is no ultimate answer but it all depends on
the respective data and if upstream happens to be moving or whatever.
It would all be less of a concern as long as we are only using testing
or unstable. What worries me is the transition of outdated instructions
to stable - and we are with a few exceptions not using backports.d.o., yet.
We could think about maintaining such download instructions online.

I am very much with you. getData once set out to do just that.
My hunch was that with something close to Perl (or any other scripting
language) we would not be limited to any official commands for the post
installation. And everyone would immediately see what the instructions mean.
> Regarding Biomaj/Getdata/other, what would be required I think is a generic tool name and to use system alternatives. User would set in Depends either the generic name (for any) or a specific tool name. In postinst he would exec the data download/update task with the generic tool name.
I need to see it to understand it :)

It defaults to /var/lib/getdata for the moment and can be specified at
runtime.

Are you creating a user for biomaj to own the data, like dataadm? It
seems like getData should then use the same, if you don't mind.
Many greetings
