Follow-up Work


The term “maintainer” refers to an individual or group of people who serve as leaders for a given component (a service or library comprised of code and hosted on GitHub) of the Open edX platform. Maintainers provide both technical and community management. This document defines what a maintainer is, how they are chosen, and how they work together.


The Open edX platform is a service oriented platform for authoring and delivering online learning based on the Django framework. At the highest level, the platform is composed of numerous services (IDAs [1]), micro-frontends (MFEs [2]) and libraries. The code for these services and libraries is managed in git and hosted on the GitHub platform.

Each component part of the Open edX platform requires maintenance to ensure that it meets, and continues to meet, the project definition of high quality. That definition will include project standards, appropriate documentation, and fitness for use, among other things. That definition will evolve as project needs do and we learn what works and what doesn’t.

Component maintenance is work. To ensure that that work is done, a person or persons must be recognized as responsible for doing it, and held accountable for its performance.

The Open edX project, like many projects, calls this role “maintainer.” The notion of a project maintainer is typical of open-source projects and widely considered a best practice [3].

The maintainer role is a leadership role that encompasses both technical and community management elements. Both dimensions of the role are equally important. Maintainers demonstrate their fitness for this role by being part of the Core Contributor program prior to their maintainer nomination.

All non-deprecated components of the Open edX project must have one or more named maintainers. When no such maintainer(s) exist, this will be considered an urgent problem to solve.

This OEP proposes a formal definition of the role of maintainer that will be open to all qualified Open edX community members. Maintainers will be responsible for the health of platform components, but not for their performance in any particular community member’s production environment [4].


With the change in stewardship from edX to Axim Collaborative, it is essential to have a well defined plan for maintaining the platform.

In order to ensure that the project is sustainable for the long term, maintenance must be shared by the entire community. The project must be robust enough that it can tolerate firms and contributors leaving the ecosystem.

As a project we must acknowledge that maintenance is hard work, but work that must be done for the platform to be fit for use. The best way of ensuring this is to have a named person or persons who are responsible for getting the work done, a measurable definition of “well-maintained,” and feedback looks to ensure accountability and continuous improvement of our processes.



The term repository will mean a repository on the GitHub social coding platform.

The term component will typically mean the unit of software housed in a single GitHub repository. Exceptions will be made in the case of edx-platform where there may be multiple distinguishable components in that single repository. Components will typically, but not always, be hosted at the openedx GitHub organization. Components will be either “part of” or “critical to” the open-source platform.

The term maintainer will mean a named person or persons responsible for the health of the component and the component’s community. The remainder of this specification will be focused on the details of the role.

The term core contributor will mean a named person participating in the Core Contributor Program as a coding core contributor and meeting the requirements of that program.

The term maintainer scrum-of-scrums will mean the group of all maintainers. They are responsible for flagging issues to project leadership and proposing process improvements for component maintenance.

The term Technical Oversight Committee (TOC) will mean the group responsible for the overall oversight and stewardship of the Open edX project. The TOC itself was established and is governed by a formal charter. You can read the full document here.

Historical Context#

Historically, the Open edX project has not had a well-defined role of maintainer. At times, community members stepped into this role informally. The role was also part of a broader “owner” role at edX. Owners were also responsible for the health of the component they owned both in the repository and in production; owners answered the pager when something went wrong.

What Maintainers Do#

The role of the repository or project maintainer is both a community focused and a technical role [5]. Maintainers will be the public face of each component and should be welcoming and available. While maintainers should strive to always be friendly and kind in their communication, firmness and directness are equally important. Maintainers must enforce the project’s standards. In cases where a proposed change isn’t aligned with the our standards or direction, it is best to make that clear as early as possible.

Non-technical responsibilities of maintainers include:

  • Effective communication with community members, other maintainers, and project leadership

  • Selection and approval of Core Contributors with commit rights to their repositories, by participating in the comment period for Core Contributor nominees nominated to commit code to their repo(s), as part of the Core Contributor Program

  • Disciplined management to ensure that maintenance work is done

  • Enforcement of the project’s technical standards

  • Ensuring that all work related to the component, planning, design, and development occurs in public spaces, enabling all Open edX community members to read and comment on discussions. Discretion may be used in cases that might need to remain private (such as security disclosures)

  • Encouraging kindness and friendliness in project discourse, but not at the expense of enforcing the project’s technical standards. At minimum, maintainers should ensure that all discussion follows the Code of Conduct

  • Ensuring that bug reports are read, acknowledged, and prioritized in a timely fashion

Technical responsibilities of maintainers include:

  • Understanding the current component architecture and implementation

  • Ensuring that basic documentation for the component exists and is accurate

  • The ability to solve or escalate issues facing users of the component

  • Ensuring that dependencies are updated as needed to avoid security risks or use of components that or not fit for use, e.g., unsupported, not maintained, or at their end-of-life.

  • Ensuring ongoing compatibility with other components of the Open edX ecosystem as they are developed

  • Having a documented technical vision for the evolution of the component

  • The ability to promptly triage incoming requests that propose changes to or extensions of the component, assessing their appropriateness and/or routing them to proper reviewers

  • Understanding the role of the component in the overall platform and how it interacts with other components

  • Must be available to participate in the comment period for Core Contributor nominees who have been nominated to commit code to the maintainer’s repo(s), as part of the Core Contributor Program

See Jobs of the Maintainer for more details on these requirements.

It is acceptable for a component to be maintained by a team or group as long as that arrangement does not reduce the reachability of at least one maintainer or reduce accountability for the above responsibilities. The maintaining team must have ways of direct contact, such as an email address and a GitHub team, that anyone can use to get hold of someone - it is completely acceptable for the team to figure out arrangements for list monitoring, such as an “on-call” rotation.


In order to be a repository maintainer, you must

  • Be an active member of the Open edX community who has made technical contributions to the project in the last 6 months, such as feature work, upgrades, bug fixes, or architectural/design contributions

  • Abide by the Open edX Code of Conduct

  • Be a member of the Core Contributor Program with rights to the repository in question who has demonstrated excellence in the role of Core Contributor. From time-to-time, in the case of a strong candidate and project need, core contributor status and maintainer status may be conferred at the same time

  • In the case of repos being moved into the openedx GitHub organization, be an original maintainer of the code

We value the level of commitment that comes with being a Core Contributor and think it is a necessary pre-requisite to becoming a Maintainer. We want to ensure that the programs are congruent and not working at cross purposes; hours spent maintaining a component will count as Core Contributor hours. If we find that the requirement of being a Core Contributor limits participation in the Maintainers program, we may choose to revisit this requirement.


Upon acceptance of this OEP, a bootstrapping period, starting with a small pilot phase, will occur whereby 2U staff and community members will formally take on maintainership roles. Details of this period will be documented in the maintainership documents on the Open edX wiki, due to their rapidly changing nature.

The Maintainer Scrum-of-Scrums#

In order to coordinate certain maintainer responsibilities including voting on nominated maintainers, iterating on standards, and removing maintainers, minimal mechanisms for coordination are required.

For now, we will assume that maintainers will self-organize to complete the critical activities.

Coordination will typically be over asynchronous channels.

From time-to-time, a task force may be required to complete certain project-wide responsibilities like developing repository standards, as well as tools for measuring compliance to those standards.

Becoming a Maintainer#

After the bootstrapping phase, the Open edX project will need processes for adding maintainers, replacing maintainers, and ensuring that new components are maintained.

Becoming a maintainer requires fulfilling the prerequisites outlined above.

A new maintainer can be added in any of the following ways:

  • An existing maintainer or core contributor can request that a new person become a component maintainer either in conjunction with the existing maintainer or by replacing them.

  • If the component is sufficiently complex to justify multiple maintainers, those maintainers form a group and should organize internally and present a single point of contact (like teams-as-maintainers above).

In both of the above cases, the request for maintainership change should be publicized in Discourse with a comment period not less than two weeks. All community members are welcome to voice their support (“liking” the post does not count), or comment with question/concerns. Existing maintainers and core contributors may object to the nomination. If there is no objection from existing maintainers or core contributors at the end of the comment period, the role will be conferred.

We are not currently limiting staff of companies from appointing, nominating, or voting for other employees of their company. This would be impractical as, currently, single companies are locus of component maintenance work. This may be addressed in future revisions to this proposal.

New Components#

In the case of new repositories, there should be a designated maintainer named before the repository is created.

Unmaintained Components#

In the case of unmaintained components, nominations will be made to the scrum-of-scrums to fill the vacancy. Nominations can be made by any member of the community including the nominee themselves. If there is no objection from existing maintainers, the role will be conferred.

If consensus cannot be reached lazily [6], a vote of existing maintainers will be taken. Maintainers can approve a nomination with the approval of at least three quarters of the members.

Removing a Maintainer#

From time-to-time it will be necessary to remove a component maintainer. This might happen because:

  • A maintainer leaves the project or changes employment

  • A maintainer does not have the time or interest to continue in the role

  • A maintainer is unreachable

  • A maintainer is not fulfilling the responsibilities of the role

Trigger events for removing a maintainer would be:

  • A maintainer informs the project, the scrum-of-scrums, and/or the program administrators that they can no longer continue in the role

  • A maintainer has been unreachable for more than 30 days

  • A maintainer has violated the project Code of Conduct

  • A maintainer hasn’t met project quality standards consistently despite feedback

In the case that a maintainer has violated the Code of Conduct, the Governance Team, specified in the Code of Conduct, will decide what the repercussions of the violation will be, including whether the violator can continue in the role of maintainer. It should be noted that maintainers are expected to be exemplars and, as such, will be held to a high standard.

In the case that a maintainer is not meeting project quality standards consistently, the scrum-of-scrums will inform the maintainer with the expectation that their components meet standards within a calendar month. If, after a month, the quality issues are not resolved, the maintainer will be removed by the scrum-of-scrums. Additionally, a maintainer who is warned three (3) times in a single calendar year will also be removed. The program administrators serve as a backstop - any community member may contact them at any time if a problem arises and the normal channels of communication are not working.

In this situation, once the existing maintainer is removed, the component enters an “unmaintained” status. This status is to recognize that there is not another group with unlimited spare capacity to pick up the slack, and to encourage the community to find a new maintainer.

Documenting Maintainers#

As it is essential that maintainers are discoverable and reachable, the person or persons responsible for maintaining a component should be listed in the repository. Per the backstage ADR we will use a catalog-info.yaml file to capture the GitHub handles for the maintainers of a repository.

Jobs of the Maintainer#

Many of the day-to-day specifics of the maintainer role are outside of the scope of this document. For example, here we will note that maintainers are responsible for ensuring that repositories meet project standards, but not the details of those standards. Those standards - including establishing a channel for feedback, and details on how and when that channel will be monitored - will be codified in an OEP over time, but will initially be defined in the wiki page requirements for public repositories to allow rapid iteration.

The key aspects of the maintainer role fall into the following categories

  • Community Stewardship: Maintainers are representatives of the project in the community and are responsible for contributing to an environment that is welcoming, vibrant, and growing.

  • Project Management: Maintainers are responsible for ensuring that critical maintenance is done, but this doesn’t mean doing it all themselves. Effective delegation is an important maintainer skill.

  • Quality Assurance: Maintainers are responsible for the quality of their components. Quality will mean meeting defined project standards. It can also mean improving our standards or improving our processes.

  • Technical Vision: Maintainers should have a documented technical vision for their components. This vision should minimally answer the following questions:

    • What is the component for?

    • How it fits into the overall platform?

    • What are its limitations and key areas of debt?

    • What new patterns or technologies should be adopted to improve the component?

    • How it can be extended?

  • Project Documentation: Maintainers provide descriptive project information in the following documents:

    • A required README file. The specification of the README file is defined in ADR 3.

    • We additionally recommend documentation to help others understand the component, such as:

      • ADRs

      • Architecture diagrams and architecture documentation

      • A product roadmap

      • Links to a project board

  • Continuous Improvement: Maintainers should be thinking about continuously improving both software and processes.

Governance Structure#

The Maintainers program will be run by the maintainers themselves, working together with input from Core Contributors and the broader community. The program administrators will serve as a backstop for any questions or issues about the Program or governance thereof that cannot be resolved by the maintainers themselves. The Technical Oversight Committee (TOC) will be the arbiter of last resort for governance matters.

Contact the Program Administrators#

Questions about the Program can be directed to the Axim administrator(s) via the #ask-axim Slack room in the Open edX Slack. Questions or concerns of a more sensitive nature may be directed to maintainer-program-admins@axim.org.
