Thanks Samuel for poping this discussion. on sage-devel.
I have only have random remarks:
- Among mathematical softwares that offer external packages the example
of R is particulary impressive (9598 packages) [1].
- Relying on Python packaging and PyPI might be too limited for Sage at
some point (tricky dependencies, Sage recompilation needed)
- We want to test these optional packages against each sage release and
for that purpose we need a kind of proper database (and extend the
patchbot functionalities)
- the wiki is a good start for a small manually handled database

Dear sage-devel,
This is a follow-up to a discussion on sage-support [0] in which
the original poster asks a question which I will summarize as:
Having written some amount of Sage code for a project,
how can I best package it and share it with the community?
Among the answers, Vincent suggests turning the code into a pip-installable
Python package for Sage, and points to a sample such package [1], made last
week at Sage Days 79 precisely to help people do that.
Vincent also points to the wiki page [2], which consists in a list
of external packages for Sage, some pip-installable, some not.
A bit later in the discussion, William writes:
It would be great if somebody could create some sort of index
of such packages, which we could link to (or include) on sagemath.org.
This might eventually involve using some sort of tagging
(or searching) of https://pypi.python.org/pypi and/or github.
For now, this could just be a Github wiki page, which gets updated
as we become aware of packages, and which we link to from sagemath.org.
Thoughts?
I'm moving the discussion to sage-devel.
The pages "SageMath external packages" [2] and "Code sharing workflow" [3]
were created in May 2016 following discussions on various Sage mailing lists
and at Sage Days 77 about modularization and packaging of Sage.
The page [2] was a preliminary attempt at "some sort of index of such
packages", and has a link to "Packages on PyPI matching 'sagemath'" [4],
which is intended as "using some sort of tagging or searching of PyPI".
It would certainly be nice to have a similar tagging or searching of GitHub,
bitbucket, and other code repositories, to detect external packages for
Sage.
Probably the list at [2] should be turned into a better format, maybe a json
or yaml file or some appropriate database format, and be made accessible and
visible at some page on sagemath.org.
Entries in a database of Sage packages might have the following fields:
- package name
- alternate names, if applicable
- author(s)
- maintainer(s)
- short description
- long description
- keywords
- link to package home page
- link to code repository
- link to documentation
- license
- date package was created
- type of package (spkg, pip-installable, ...)
- relevant Sage trac tickets,
- discussions on sage-devel or other media
- maintenance status
- ...
We might also check how other communities index external packages,
for instance Astropy, GAP, Julia, ...
