Hi!
Thank you the details.

I mean "open source" any software publicly released with publicly
accessible source. It is large. ;-)
And I totally agree with the condition to be included or not in the
Guix infrastructure.
My point is that a lot of softwares released in scientific world will
never reach such condition. It is sad and I think all people here are
trying to change by convincing the authors. But, it is a pragmatic
fact.
Hum? I am not sure to get your point about GNU compliance. For example,
https://libreplanet.org/wiki/List_of_software_that_does_not_respect_the_Free_System_Distribution_Guidelines
`apt' and `debian-installer' illustrate the well-known and famous
debate between RMS and Debian. :-)

Yes, the GNU FDSG defines "free" (as in speech). And there is "open
source" softwares which are not included in this definition (for the
good, for the bad, I am not arguing).
https://www.gnu.org/licenses/license-list.html#NonFreeSoftwareLicenses
For example, some versions of Scilab (clone of Matlab) with a "weird"
license (CeCILL-2).
For the record, let indicate an historical point:
https://www.gnu.org/licenses/bsd.html :-)
I am not arguing about "bad" practices. I am just pointing that the
situation of scientific softwares is often really complicated. Because
they often glue a lot of different piece of softwares, e.g.,
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=617931
Note that, in the same way that non-free parts are removed from
`shogun', the guix package `gmsh' removes METIS non-free part (which
is "open source"). Hope that this clarifies my point and feeds
argument about channel. :-)

Thank you to clarify the way.
If I understand well, additional meta-data should be manually provided by Alice.
Extract a manifest is some UI glue, even, it is perhaps already possible.
However, the Guix version do not appear to me straightforward. Does
this information should be included when installing a package ?

Should be possible to extract all the required information from a
profile with a kind of `guix pack' at the source level ?
This should be useful ? or not at all and I am wishing a twisted process ?
Thank you for your insights.
And for sharing the MDC's configuration!
All the best.
