Governance

This document describes the governance process under which the CloudEvents project will manage this repository.

For easy reference, additional documentation related to how this project, and its subprojects, operate are listed below:

Meetings

In order to provide equitable rights to all members, the following process will be followed:

  • Official conference calls will be announced at least a week in advance.
  • Official face-to-face meetings will be announced at least 4 weeks in advance.
  • Proposed changes to any document will be done via a Pull Request (PR).
  • PRs will be reviewed during official meetings, but off-line reviews (LGTMs, NOT LGTMs) and comments are strongly encouraged to gauge the group's opinion on the proposed change prior to the meeting.
  • During meetings, priority will be given to PRs that appear to be ready for a vote over those that appear to require discussions. See PRs for more information.
  • PRs should not be merged if they have had substantial changes made within two days of the meeting. Rebases, typo fixes, etc. do not count as substantial. Note, administrivia PRs that do not materially modify output documents may be processed by admins as needed.
  • Resolving PRs ("merging" or "closing with no action") will be done as a result of a motion made during a meeting, and approved.
  • Reopening a PR can be done if new information is made available, and a motion to do so is approved.
  • Any motion that does not have "unanimous consent" will result in a formal vote. See Voting.

Membership

There are three categories of project membership:

  1. Member. This is anyone who participates in the group's activities in any of our communication channels (email, github issues/PRs, meetings, etc.). No formal registration process is needed.

  2. Voting Member. See the Voting section below for more information on how the list of Voting Members are determined. During the normal operations of the group, Voting Members and Members are the same with respect to influence over the groups actions. The rights associated with being a Voting Member only apply in the event of a formal vote being taken.

  3. Admin. Admins are Members of the group but have the ability to perform administrative actions on behalf of the group. For example, manage the website, github repos and moderate the meetings. Their actions should be done with the knowledge and consent of the group. They also have the ability to merge/close PRs, but only per the group's approval. See the OWNERS file for the current list of Admins.

Admins

Since the role of an 'Admin' is mainly administrative, the list of Members within this group should not need to change regularly. The following rules govern adding and removing Admins:

  • New Admins can be proposed via a PR to edit the OWNERS file. Normal PR voting rules apply.
  • Admins can be removed via a PR to edit the OWNERS file. Normal PR voting rules apply.
  • Admins can request to be removed via a PR to edit the OWNERS file. Since the group can not force an Admin to continue in that role, the PR does not follow the normal voting rules and can be merged by any of the Admins, including the person requesting to be removed. The exception to this "self-merge" aspect is when they are the last Admin. See next bullet.
  • If a PR to edit the list of Admins would result in there not being any Admins remaining, then the state of the project would need to be decided first since a project without any Admins might imply that the project should be shutdown.

PRs

Typically, PRs are expected to meet the following criteria prior to being merged:

  • The author of the PR indicates that it is ready for review by asking for it to be discussed in an upcoming meeting - eg. by adding it to the agenda document.
  • All comments have been addressed.
  • PRs that have objections/concerns will be discussed off-line by interested parties. A resolution, updated PR, will be expected from those talks.

Anyone is welcome to comment on PRs, not just Admins, voting members or regular call participants. The goal of the project is consensus and broad community support, so community input is strongly encouraged.

Voting

If a vote is taken, the follow rules will be followed:

  • There is only 1 vote per participating company, or nonaffiliated individual.
  • Each participating company can assign a primary and secondary representative.
  • A participating company, or nonaffiliated individual, attains voting rights by having any of the entity's assigned representative(s), in aggregate, attend 3 out of the last 4 meetings. The people listed as "primary" or "alternate" for an entity can be changed no more than once a month and can be changed by notifying one of the admins. The entity obtains voting rights after the 3rd meeting, not during.
  • A "primary" or "alternate" member may request a leave-of-absence via an e-mail to the mailing list, or a message to the public slack channel, prior to the absence. An acceptable absence would include situations where the person is not officially working at all, such as being on vacation, taking a sabbatical or there is a public holiday. However, situations such as a scheduling conflict would not apply. Absence from meetings during a leave-of-absence will not impact their voting rights.
  • Only members with voting rights will have their vote counted towards the decision.
  • A vote passes if more than 50% of the votes cast approve the motion.
  • Only "yes" or "no" votes count, "abstain" votes do not count towards the total.
  • Meeting attendance will be formally tracked here. Members must acknowledge their presence verbally, meaning, adding yourself to the "Attendees" section of the Agenda document is not sufficient. An Admin will be responsible for updating the spreadsheet.
  • When a vote is called, unless all voting members have voted, the vote will be tallied no less than one week after calling the vote.
  • Voting process:
    • Comment on the PR: "YES VOTE", "NO VOTE", or "ABSTAIN".
    • Any person is encouraged to vote with a statement of support or dissent to help undecided voters to reach a decision
    • Comments are welcome from non-members
    • Voting tally will reflect the above qualification and recorded in PR

Release Process and Versioning

The specifications produced will adhere to the following:

  • The versioning scheme used will follow semver
  • All normative specifications, and the Primer, will be grouped together into a single logical unit and released at the same time, at the same version number. This is true regardless of whether each individual document actually changed during the release cycle.
  • When a new release of a specification is ready, it will be given a version number matching the appropriate semver version string but with a suffix of -rc# (release candidate). This will indicate that the authors believe it is ready for final release but it needs to go through a testing period to allow for broader testing before it promoted to its final version number. This will be true for updates to existing specifications and for new specifications.
  • Since changing the CloudEvents specversion string could have a significant impact on implementations, all non-breaking changes will be made as "patch" version updates - this allows for the value "on the wire" to remain unchanged. If a breaking change is introduced the normal semver rules will apply and the "major" version number will change. The net effect of this is that the "minor" version number will always be zero and the specversion string will always be of the form X.0.

Note that these rules do not apply to the documented extensions.

All versions are tagged from the main branch, but the tag only applies to the "subject" of the release - the directory containing the information covered by that release (e.g. subscriptions or cloudevents). The CloudEvents web site takes appropriate content from each tagged version. (If the directory containing the information covered by the release is not in a top-level directory, the subject should be the full path, e.g. top-dir/sub-dir.)

Note: should the need arise, additional branches may be created. For example, it is likely that a core-v2.0 branch will be created to collect changes for the core specification version 2.0 significantly before those changes are merged into the main branch, to allow for ongoing work on the main branch. Such branches should be deleted once their content is eventually merged.

To create a new release:

  • Periodically the group will examine the list of extensions to determine if any action should be taken (e.g. removed due to it being stale). The creation of a new release will be the reminder to do this check. If any changes are needed then PRs will be created and reviewed by the group.
  • Create a PR that modifies the README, and all specifications (ie. *.md files) that include a version string, to the new release version string. Make sure to remove -wip from all of the version strings.
  • Merge the PR.
  • Create a new release:
    • Choose a "Tag version" of the form: <subject>/vX.Y.Z, e.g. cloudevents/v1.0.4 or subscriptions/v1.0.0
    • Target should be main, the default value
    • Release title should be the same as the Tag - <subject>/vX.Y.Z
    • Add some descriptive text, or the list of PRs that have been merged since the previous release. The git query to get the list commits since the last release is: git log --pretty=format:%s main...v0.1 | grep -v "Merge pull". Just replace "v0.1" with the name of the previous release.
    • Press Publish release button
  • Create an "announcement" highlighting the key features of the new release and any potential noteworthy activities of the group:
    • Send it to the mailing list
    • Announce the release on our twitter account
    • Add it to the "announcement" section of our website
