About
The ultimate goal for this program is to provide ways for the user community to ensure the long-term sustainability of the development and maintenance of some Typelevel libraries.
Based on the Cats ecosystem community survey 2018 results, as well as feedback from potential donors, we adopted the following principles for the program:
Principles:
* Paid maintainers focus on supporting the community contributors. In another sentence, paid maintainers’ first task is to maintain the community-driven development.
More detailed responsibilities are listed below.
* Main obligations to sponsors (individual or corporate) are limited to
- The existing license remains unchanged.
- Timely security patches and mission-critical bug fixes.
- Financial contributions will NOT grant contributors extra influence over the development.
- Financial contributors can influence how their contribution is distributed among projects.
* The program is governed by an independent committee.
* As part of our community, sponsors hold values compatible with the Scala Code of Conduct.
Responsibilities for paid maintainers
Relevant tasks:
* Create/maintain contribution guidance documentation
* Review PRs in a timely fashion
* Create friendly issues for first-time contributors
* Provide real-time tech support for contribution related topics
Relevant tasks:
* Maintain/improve infrastructure, e.g. build, tests, linting etc.
* Plan and manage releases
* Backports to support of old Scala version
* Create documentation
Goal 3: Ensure the ecosystem is unblocked
Relevant Tasks:
* Fix mission-critical bug
* Address security vulnerabilities
* Enforce compatibility guarantees
* Take on initiatives that require a significant amount of effort usually too large for casual contributors to
take on, e.g. complete Scala 2.13 migration; merging in typelevel/algebra; integration with Scala 3.0 std library, etc.
Funding source
We rely on donations from corporation and individual users of the OSS libraries. Aside from monetary assistance, companies can support us by:
* Providing computing resources/tools such as CI systems, communication platforms, development tools, etc.
* Paid employees' time for code contributions
* Sponsor events such as free training, conferences, by providing the venue, food, etc.
* Donation of training/support services or coupons that we can then exchange for monetary contributions.
Perks for sponsoring companies include
* Branding on our sponsors' list (at $200 per month or 100 paid employee hours per year)
* Job posts (at $500/month level)
* Training / Technical support (if we receive such donations)
We reserve the right to respectfully decline sponsorship offers.
