I agree!

I agree that something is missing.

I agree too.

Related to this idea, I would point to [1] a previous discussion about
"pure" data package distribution.
[1] https://lists.gnu.org/archive/html/guix-devel/2018-02/msg00183.html
For a concrete example, let consider the Debian package [2]
'astrometry-data-2mass-00' which is roughly 13.9GB of data. A big set
of index used by astronomer. The Debian package calls 'curl' under the
hood to fetch the data from the http://data.astrometry.net; see [3].
[2] https://packages.debian.org/fr/stretch/astrometry-data-2mass-00
[3] https://salsa.debian.org/debian-astro-team/astrometry-data-2mass/blob/master/debian/astrometry-data-2mass-00.postinst
Well, the questions are:
- hash?
- a copy on Berlin as substitute?
I am just taking the occasion to discussion the hypothetical
possibility to discuss if 'copy-build-system' could be way to
distribute such data set.
Other said, the 'copy-build-system' could:
- fetch the data from an archive, such http://data.astrometry.net
- fetch the resulting <hash> of /gnu/store/<hash>-name-version from susbtitutes
Cheers,
simon
