It has these specific goals: + +- To maximize the scale and diversity of the community around a project, by reducing the friction for new Contributors and creating a scaled participation model with strong positive feedbacks; +- To relieve dependencies on key individuals by separating different skill sets so that there is a larger pool of competence in any required domain; +- To allow the project to develop faster and more accurately, by increasing the diversity of the decision making process; +- To support the natural life cycle of project versions from experimental through to stable, by allowing safe experimentation, rapid failure, and isolation of stable code; +- To reduce the internal complexity of project repositories, thus making it easier for Contributors to participate and reducing the scope for error; +- To enforce collective ownership of the project, which increases economic incentive to Contributors and reduces the risk of hijack by hostile entities. + +## Design + +### Preliminaries + +- The project SHALL use the git distributed revision control system. +- The project SHALL be hosted on github.com or equivalent, herein called the "Platform". +- The project SHALL use the Platform issue tracker. +- The project SHOULD have clearly documented guidelines for code style. +- A "Contributor" is a person who wishes to provide a patch, being a set of commits that solve some clearly identified problem. +- A "Maintainer" is a person who merges patches to the project. Maintainers are not developers; their job is to enforce process. +- Contributors SHALL NOT have commit access to the repository unless they are also Maintainers. +- Maintainers SHALL have commit access to the repository. +- Everyone, without distinction or discrimination, SHALL have an equal right to become a Contributor under the terms of this contract. + +### Licensing and Ownership + +- The project SHALL use a share-alike license, such as the GPLv3 or a variant thereof (LGPL, AGPL), or the MPLv2. +- All contributions to the project source code ("patches") SHALL use the same license as the project. +- All patches are owned by their authors. There SHALL NOT be any copyright assignment process. +- The copyrights in the project SHALL be owned collectively by all its Contributors. +- Each Contributor SHALL be responsible for identifying themselves in the project Contributor list. + +### Patch Requirements + +- Maintainers and Contributors MUST have a Platform account and SHOULD use their real names or a well-known alias. +- A patch SHOULD be a minimal and accurate answer to exactly one identified and agreed problem. +- A patch MUST adhere to the code style guidelines of the project if these are defined. +- A patch MUST adhere to the "Evolution of Public Contracts" guidelines defined below. +- A patch SHALL NOT include non-trivial code from other projects unless the Contributor is the original author of that code. +- A patch MUST compile cleanly and pass project self-tests on at least the principle target platform. +- A patch commit message SHOULD consist of a single short (less than 50 character) line summarizing the change, optionally followed by a blank line and then a more thorough description. +- A "Correct Patch" is one that satisfies the above requirements. + +### Development Process + +- Change on the project SHALL be governed by the pattern of accurately identifying problems and applying minimal, accurate solutions to these problems. +- To request changes, a user SHOULD log an issue on the project Platform issue tracker. +- The user or Contributor SHOULD write the issue by describing the problem they face or observe. +- The user or Contributor SHOULD seek consensus on the accuracy of their observation, and the value of solving the problem. +- Users SHALL NOT log feature requests, ideas, suggestions, or any solutions to problems that are not explicitly documented and provable. +- Thus, the release history of the project SHALL be a list of meaningful issues logged and solved. +- To work on an issue, a Contributor SHALL fork the project repository and then work on their forked repository. +- To submit a patch, a Contributor SHALL create a Platform pull request back to the project. +- A Contributor SHALL NOT commit changes directly to the project. +- If the Platform implements pull requests as issues, a Contributor MAY directly send a pull request without logging a separate issue. +- To discuss a patch, people MAY comment on the Platform pull request, on the commit, or elsewhere. +- To accept or reject a patch, a Maintainer SHALL use the Platform interface. +- Maintainers SHOULD NOT merge their own patches except in exceptional cases, such as non-responsiveness from other Maintainers for an extended period (more than 1-2 days). +- Maintainers SHALL NOT make value judgments on correct patches. +- Maintainers SHALL merge correct patches from other Contributors rapidly. +- The Contributor MAY tag an issue as "Ready" after making a pull request for the issue. +- The user who created an issue SHOULD close the issue after checking the patch is successful. +- Maintainers SHOULD ask for improvements to incorrect patches and SHOULD reject incorrect patches if the Contributor does not respond constructively. +- Any Contributor who has value judgments on a correct patch SHOULD express these via their own patches. +- Maintainers MAY commit changes to non-source documentation directly to the project. + +### Creating Stable Releases + +- The project SHALL have one branch ("master") that always holds the latest in-progress version and SHOULD always build. +- The project SHALL NOT use topic branches for any reason. Personal forks MAY use topic branches. +- To make a stable release someone SHALL fork the repository by copying it and thus become maintainer of this repository. +- Forking a project for stabilization MAY be done unilaterally and without agreement of project maintainers. +- A stabilization project SHOULD be maintained by the same process as the main project. +- A patch to a stabilization project declared "stable" SHALL be accompanied by a reproducible test case. + +### Evolution of Public Contracts + +- All Public Contracts (APIs or protocols) SHALL be documented. +- All Public Contracts SHOULD have space for extensibility and experimentation. +- A patch that modifies a stable Public Contract SHOULD not break existing applications unless there is overriding consensus on the value of doing this. +- A patch that introduces new features to a Public Contract SHOULD do so using new names. +- Old names SHOULD be deprecated in a systematic fashion by marking new names as "experimental" until they are stable, then marking the old names as "deprecated". +- When sufficient time has passed, old deprecated names SHOULD be marked "legacy" and eventually removed. +- Old names SHALL NOT be reused by new features. +- When old names are removed, their implementations MUST provoke an exception (assertion) if used by applications. + +### Project Administration + +- The project founders SHALL act as Administrators to manage the set of project Maintainers. +- The Administrators SHALL ensure their own succession over time by promoting the most effective Maintainers. +- A new Contributor who makes a correct patch SHALL be invited to become a Maintainer. +- Administrators MAY remove Maintainers who are inactive for an extended period of time, or who repeatedly fail to apply this process accurately. +- Administrators SHOULD block or ban "bad actors" who cause stress and pain to others in the project. This should be done after public discussion, with a chance for all parties to speak. A bad actor is someone who repeatedly ignores the rules and culture of the project, who is needlessly argumentative or hostile, or who is offensive, and who is unable to self-correct their behavior when asked to do so by others.
