Q9: Why do you want your project to join NumFOCUS?

Our project will benefit from engaging closely with projects and organizations that have modern open-source governance structures.

Q10: Are you applying for Fiscal Sponsorship or Affiliation? For more information, see https://numfocus.org/projects-overview

B. affiliation

Q11: Integration with the existing ecosystem of NumFOCUS tools

Cython, CVXpy, igraph, IPython, Jupyter, Matplotlib, NetworkX, NumPy, SciPy, SymPy are dependencies of SageMath. Additionally, volunteers maintain conda-forge packaging of SageMath.

Details: Integration with NumFOCUS Sponsored Projects

The sponsored projects IPython, Jupyter, Matplotlib, NetworkX, NumPy, SciPy, SymPy are dependencies of SageMath. Additionally, volunteers maintain conda-forge packaging of SageMath.

IPython and Project Jupyter are essential dependencies of SageMath:

• TODO shared history
• https://github.com/ipython/ipython/blob/main/.github/workflows/downstream.yml

Possible future integration with scikit-image

• #37494 add scikit-image as a Sage package
• Examples using scikit-image could refresh some SageMath tutorials, for example on linear algebra

Details: Integration with NumFOCUS Affiliated Projects

The affiliated projects CVXPY, Cython, igraph are dependencies of SageMath.

Cython is an essential dependency of SageMath:

• The Sage library contains over 500 Cython modules.
• TODO shared history
• Sage switched to the Cython 3.0 series in Sage 10.2, released December 2023.

Possible integration with Spack, package manager for HPC systems:

• This could improve the reach of SageMath to use on HPC systems, although viable alternatives such as conda-forge exist.
• Using Spack Packages as an upstream for SageMath's dependencies:
  • Add system package information files SAGE_ROOT/build/pkgs/*/distros/spack.txt
  • Add portability tests for building in Spack environments, e.g. based on spack containerize
• Downstream packaging of SageMath in Spack Packages: Various dependencies of SageMath already exist but are not up to date (e.g. gmp, suite-sparse) and are marked as "looking for a maintainer".

Q12: Describe how your project furthers the NumFOCUS mission: https://numfocus.org/community/mission

SageMath is mathematical software with an integration mission.

Q13: How many active contributors does your project currently have?

70

Q14: Any comments you’d like to make on the number of your active contributors:

as per https://github.com/sagemath/sage/graphs/contributors?from=2023-02-09&to=2024-01-13&type=c

Q15: What is your project doing to attract and/or mentor new contributors and maintainers?

Organize virtual and in-person workshops, participate in Google Summer of Code

Q16: Where do you host conversations about project development and governance (e.g. mailing lists, forums, etc.), and how many participants do you have?

https://groups.google.com/g/sage-devel, TBD participants

Q17: What license(s) does your project currently use?

GPL v2+, GPL v3+

Q18: Projects must adopt the NumFOCUS Code of Conduct or one similar in spirit. Please tell us how you plan to meet this requirement: https://numfocus.org/code-of-conduct

https://github.com/sagemath/sage/blob/develop/CODE_OF_CONDUCT.md was adopted in 2014

TODO: Describe the Maintainers role: Duties, privileges, appointment procedure

• Duty (daily): Approve workflow runs for PRs by new contributors that are waiting for approval
  • to batch-delete workflow runs that never got approved and do not need to be run any more: gh run list --status action_required --branch pol-quotient-deg --limit 200 --json databaseId --jq '.[].databaseId' | xargs -n 1 gh run delete
• Duty (weekly): Assign closed issues, merged PRs without release milestone to the current milestone
• Duty (weekly): Monitor the workflows CI Linux (default), push to Docker Hub, publish to GH Releases and PyPI; hot-fix and restart if necessary
• Duty (weekly): Monitor the long-running CI workflows of development releases (check for broken portability)
• Duty (monthly): Monitor the long-running CI workflows of development releases (check for broken optional packages)
• Duty (monthly): Organize preparation of Release Tours
• Duty (monthly): Open a new release milestone when it is time
• Duty: Add people to the Triage role when appropriate
• Duty: Create new labels when appropriate
• Duty: Monitor/configure the GH Actions workflow that updates labels https://groups.google.com/g/sage-devel/c/sulCa-6EZRA/m/6P6ZCCzkAAAJ
