Governance of the OCaml.org domain

Overview and Scope

As the OCaml community continues to grow, more collaborative work is being undertaken to support and extend the needs of the language and its users. This document focuses specifically on the OCaml.org domain name and the Projects that make use of that domain name. It describes the reporting structure, roles involved and the responsibilities. The aim is to avoid introducing cumbersome processes while still providing a high degree of transparency.

Purpose - a document that represents reality

At any given time, this document must reflect the current reality. It is not intended to be aspirational nor reflect the kind of structures that people may expect to see. This is an important point because the utility of this document is limited to the extent that it represents how things really are, as opposed to how people may desire them to be in the future. As the environment changes, this document should also be updated such that it consistently reflects how things are.

Disambiguation - the meaning of OCaml.org

When using the term 'OCaml.org', there is the potential for a number of different interpretations. To reduce confusion, these are described below and the meaning of the term for this document is explained.

Second-level domain name - This is the domain name we are familiar with, 'OCaml.org', which has associated sub-domains and records (NB: Just for clarity and edification, the top-level domain here is '.org').

Community website - This is the community facing website, which can be found at ocaml.org and is often referred to as simply 'OCaml.org'.

Infrastructure - This may refer to the virtual machines (VMs), services or other things that are somehow routed via the second-level domain name itself. An obvious example is the VM that hosts the community website but another would be the VMs and systems that host the tarballs and files used by the OPAM package manager tool.

For the purposes of this document, we take the first meaning — that this document relates to the governance of the second-level domain, 'OCaml.org'. Therefore, anything that involves use of the domain name in some form is affected by the governance of the domain name itself. That includes any public facing webpages, URLs and other resources. This is important because, in a way, OCaml.org is the sum of the Projects it hosts.

To avoid confusion between the domain name itself and the community website Project, the term 'OCaml.org' in this document refers only to the second-level domain name itself. Any references to the domain of the community website project will include the sub-domain 'www.ocaml.org', even though this is set to redirect to ocaml.org.

Guiding principles of OCaml.org

There are certain guiding principles for OCaml.org, which include openness and a community-focus, that Projects need to be compatible with. These principles extend to all of the Projects that use the domain OCaml.org.


Owner and Delegates

The Owner of OCaml.org is Xavier Leroy, the lead developer of the OCaml language. Projects under OCaml.org sub-domains are managed by the community, meaning that it is the community that actively contributes to the day-to-day maintenance of any OCaml.org Project, but the general strategic direction is drawn by the Owner.

It is the role of the Owner to resolve disputes that may arise in relation to OCaml.org itself, specifically to ensure that the Projects under OCaml.org are able to progress in a coordinated way. It is the community's role to guide the decisions of the Owner through active engagement, contributions and discussions. To foster a healthy and growing community, the Owner will make the goals and decisions clear and public.

It is anticipated that the Projects themselves will be self-managing and will resolve issues within their communities, without recourse to the Owner. Where the Owner needs to become involved, he/she will act as arbitrator.


The Owner may choose to delegate authority to others to manage the domain and act in the Owner's name, though ownership remains with the Owner. Those Delegates are free to choose how they arrange themselves, in agreement with the Owner. In the specific case of disputes, the Delegate(s) will consult with the Owner, who will act as arbitrator if required.

Currently, Xavier Leroy has delegated responsibility for OCaml.org to Anil Madhavapeddy, who has accepted this Role.


Projects under OCaml.org will have their own Maintainers, who have commit access to relevant repositories and are responsible for:

  • Managing the specific project.
  • Writing code directly to repositories.
  • Eliciting and screening the contributions of others.
  • Ensuring that the Owners/Delegates are aware of community needs.

Generally, Maintainers only have authority over the specific Projects they are responsible for though it is expected that Maintainers of different Projects will collaborate frequently, especially in the case of major changes or announcements. Typically, individuals who have made substantive contributions to a Project will be invited to become Maintainers.


Contributors are wider members of the OCaml community who make valuable contributions, but generally do not have authority to make direct changes to a Project's code-base or documentation. Anyone can become a Contributor and there is no expectation of commitment, no specific skill requirement and no selection process. The only necessary step is to make or suggest some improvement or change to the Project.

Contributors can interact with a Project via tools such as email lists, issue trackers and wiki pages, for example. The main email list for OCaml.org is infrastructure@lists.ocaml.org and is open to all. Maintainers are free to direct discussion to their own dedicated mailing lists, as they feel appropriate. Those whose contributions become part of a public git repository will be recognised in some form on a public website as thanks.

It is expected that regular Contributors to specific Projects may be asked if they wish to become Maintainers, as described above. There is no obligation to accept such an offer.


Users are the most important group and it includes the much wider community of anyone who interacts with OCaml.org in any way. This covers all web-visitors, package users, and members of mailing lists. Without Users, the Projects serve no purpose so the impact of any major decisions on this group should be assessed.

Wherever practicable, Users should be encouraged to provide feedback and participate in the Projects as much as possible. Users who engage a lot with a Project will likely go on to become Contributors.

It should be noted that these Roles are not mutually exclusive, for example Maintainers and Contributors are necessarily also Users.


Definition - A Project within OCaml.org is characterised by its sub-domain. It is expected that the majority of new work will fall under an existing sub-domain and will therefore already have a set of Maintainers and Contributors (as described above).

Communication - All Maintainers of Projects must join the Infrastructure mailing list (infrastructure@lists.ocaml.org). This list is the primary way that information and decisions surrounding OCaml.org will be discussed and disseminated. If Projects wish to set up their own lists, they may do so on lists.ocaml.org (see below).

Governance - Projects are free to choose their mode of governance provided it is compatible with the governance and guiding principles of OCaml.org.

Initiating a Project

Any proposal for new work should be raised and discussed on the Infrastructure mailing list. If there is consensus among Maintainers that the work fits within an existing Project, then the Maintainers of that Project can take it forward.

If a new sub-domain is required, then a brief proposal should be made on the Infrastructure list that covers:

  • The aims and purpose of the Project (inc name of the sub-domain required).
  • Specific resources required and for how long (e.g VMs).
  • Any impact on or relation to existing Projects.
  • Information about the initial Maintainers.
  • Details of proposed licensing arrangements for code/content.

The above information is intended to stimulate discussion so brevity is preferred. Following discussion, and if the Owner/Delegate agrees, the resources can be provisioned. There is no obligation for the Owner/Delegate to provide any resources beyond the sub-domain.

Closing a Project

A Project can be closed:

  • If it has completed its aims and the Maintainers request it be closed down.
  • If there are no Maintainers left to continue supporting it and no-one willing to take on the role.
  • By the Owner/Delegate for any reason.

In all cases, prior notice must be sent to the Infrastructure list including a reasonable time-frame and reasons for closure. Closure simply implies revocation or redirection of the sub-domain and/or shutting down or reclaiming any resources provided (e.g VMs).


Decision Making and Communication

The preferred approach for most discussions is through rough consensus and running code. Discussions should be public and take place on either the Infrastructure mailing list, the relevant Project mailing-list or on relevant issue trackers. Users and Contributors are encouraged to take part and voice their opinions. Typically, the Maintainers of a Project will make the final decision, having accounted for wider views.

All Projects under OCaml.org are to be documented such that Users can find out about them and understand both the purpose and how they can contribute.

Contribution Process and Licensing

Contributions to OCaml.org will primarily be to one or more of its Projects. Each Project under OCaml.org needs to define a clear contribution process and licensing agreement so that Contributors understand how to engage with the Maintainers. Typically, this will cover where communication occurs and the process for submitting patches. Contributions from the community are encouraged and can take many forms including, bug fixes, new features, content or documentation.

All Projects under OCaml.org are expected to be open-source and the licensing arrangements should reflect this.

Contributions to OCaml.org itself may be in the form of resources that can be shared by Projects and can be discussed with Owner/Delegate and Project Maintainers on the Infrastructure mailing list.

Dispute resolution

Maintainers are expected to make decisions regarding their Projects. The intent is for any Maintainers to resolve disagreements, through a consensus process within each Project.

On the rare occasions, where Maintainers of a Project cannot agree on a way forward the following approach is suggested:

  • The specific issue(s) will need to be articulated so it is clear what needs to be discussed.
  • Other Maintainers of OCaml.org projects will be asked for their views.
  • If the discussion still cannot be resolved, the Owner (or their Delegate) will act as arbitrator.

During the above, it is expected that all people will be reasonable and be respectful of each other's efforts and viewpoints. In general, we expect to generate consensus among the community to resolve conflicts.

Existing Projects

Projects are referred to by their sub-domain and summaries of the current Projects are maintained on the Infrastructure wiki page: https://github.com/ocaml/infrastructure/wiki

Adoption of this document

This version of the document was agreed upon by the incumbent set of Maintainers in September 2015. You can look back at the discussion or see the related issue.
