Community-led development "The Apache Way"
This guide outlines the general responsibilities of PMC members in managing their projects and common how-to procedures for day to day maintenance. For a high-level overview of the what and why of PMCs, please read the PMC Governance overview.
This document is for PMC members of ASF projects. A Project Management Committee (PMC) is responsible for the proper management and oversight of an Apache project, and reports directly to the board four times a year. Every PMC has a Chairperson, who is also an officer of the ASF with the title "Vice President, Apache Projectname".
A project management committee (PMC) is a committee of the Apache Software Foundation charged with responsibility and governance for their top level project. The PMC is the vehicle through which decisio- making power and responsibility for oversight devolves to developers.
While committers on a project have the ability to update the code, only the PMC as a body has the authority to vote on formal releases of the project's software. The PMC is also responsible for voting in new committers and PMC members to the project, as well as following other policies as outlined in this document.
Terms in this section as used as per RFC2119. The Board expects all PMCs to understand and comply with these policies.
PMC Chairs / Vice Presidents SHALL submit a report on their project health on a quarterly basis to the Board, or when requested by a director. In the absence of the PMC Chair, or at their direction, any other PMC members may write and submit the report.
Similarly, PMC Chairs SHALL provide replies to board questions about the PMC report or other project operations to the board@ mailing list and will ensure the PMC takes any actions required by the board.
PMC Chairs/Vice Presidents have specific additional duties listed below.
PMCs SHALL ensure that the work on their project and the code that they produce comply with relevant Legal Affairs Committee policies, including appropriately using the Apache License, handling IP and copyrights correctly, handling cryptography, and producing official software releases of their products.
PMCs SHALL ensure that they manage their projects brand and treat
all Apache® marks properly as defined both in the overview of
PMC Branding Responsibilities and the Apache Project Branding Requirements for project websites.
PMCs SHALL review use of their Apache project brand by third parties and follow the Apache Trademark Use Reporting Guidelines when appropriate.
All technical decisions and the great majority of the work of any PMC should be done on their normal public mailing lists, such as dev@ or user@. Decisions SHALL NOT be made in other media, like IRC or face to face at conferences; discussions from such settings must be brought back to the appropriate mailing list for all participants to discuss and decide upon.
PMCs SHOULD ensure that decision-making processes allow input for a sufficient amount of time - typically at least 72 hours - so that project participants in various time zones have a chance to participate in the decision.
All PMCs SHALL restrict their communication on private mailing lists to only issues that cannot be discussed in public, such as discussion of:
All projects SHALL use the name
private@*project*.apache.org for this
private list (where project is the name of the project). PMC members must
maintain the confidentiality of messages on privately archived mailing lists.
PMC chairs should monitor the minutes of board meetings that are relevant to their project, especially any comments directors make on their project's reports reports, and pass relevant information back to the project PMC, and otherwise serve as a conduit for any questions between the board and the PMC.
Note: Feedback from the board and the unedited minutes of board meetings is not normally public information, and should be treated confidentially. Only after the board has formally approved the minutes of a meeting (normally the following month) are they published publicly. Feedback on meeting minutes is usually sent to the private@ list.
While the PMC chair is not required to write the quarterly board report personally, they are responsible for ensuring the report is complete and submitted on time.
Remember that, as in any committee, the chair is a facilitator and their role within the PMC is to ensure that everyone has a chance to be heard and to enable meetings and mailing lists to flow smoothly. A well run PMC works together to draw up the information for their board report, but the chair is specifically responsible for getting it to the board. There is no concept of "leader" in the Apache way.
After the project has elected new committers and followed the process to get their account created, the PMC chair ensures the new committer has karma (access) to the project repositories.
Maintain info about your PMC composition in the SVN "committers" repository at committee-info.txt and keep it up-to-date; remember to update the LDAP committee group as well.
Be aware of anything currently in incubation at incubator.apache.org.
board@mailing list if desired¶
PMC Chairs are welcome to subscribe to the
board@ mailing list to stay aware of Foundation level issues that may affect
their project. This used to be a requirement but the Board made it optional in June 2020. Note that
board@ is a privately
archived mailing list, so information from board@ must NOT be forwarded elsewhere. ; however, as officers of the ASF, PMC
Chairs are welcome to subscribe.
If your PMC wishes to change their VP / Chair, typically you hold
a vote or otherwise reach a consensus in the PMC about who the
new Chair should be. Then anyone on the PMC can
board@ an official resolution for the board to approve (or reject) at the next monthly board meeting
before this change officially takes place.
Use the Whimsy Board Agenda
(requires Apache login) to submit the formal chair change resolution to
the next month's board meeting. Log in to the Board Agenda and click the
add item button at the bottom to add the appropriate resolution. If your PMC
members have difficulty logging into Whimsy, contact the
board@ mailing list for help.
Yes, they are officers of the corporation, and no, they are not "Members". PMC Chairs are appointed by the board to be both the Vice President of their top level project and to serve as the Chair of their Project Management Committee. Read an explanation why PMC Chairs are legal officers of the corporation.
PMC Chairs/VPs are not necessarily Members of the ASF. Members of a PMC and the Chair/VP have merit within their project, which is different than the governance of the ASF as a whole Foundation. Members of the Foundation are essentially shareholders in the legal corporation that hosts our 100s of software projects.
The board reads each submitted project report at its monthly meetings, and sometimes
individual directors make comments or ask questions in the Whimsy tool of
the meeting agenda. Shortly after each month's meeting, the Secretary uses
Whimsy to automatically send all comments out to each project's
mailing list and to the PMC chair directly.
Some comments are simple feedback or notes on the report; some comments are
specific questions from directors. If there is any question
or unusual feedback in this email, the board expects that a PMC member
will send areply-all response to
As described on its homepage, the Attic is meant to provide oversight for projects which otherwise would not have oversight.
It's fine for ASF projects to be mature and quiet, with little development activity happening, and that in itself is not a reason to move to the Attic.
However, to be viable, an ASF project must have enough active PMC Members who provide oversight for the project. They fix and release code and handle security vulnerabilities or other serious bugs, for example.
While the PMC doesn't have to fix all the bugs or requests that come in, the Board must be able to verify that there are at least three PMC members monitoring the project's mailing lists who could reply and act in such cases.
To this end, the Board will sometimes perform a PMC roll call.
Sometimes, members leaving a project would result in fewer than three PMC members remaining, while other community members are willing to continue maintaining the project. In such a case, the best way forward, if possible, is to elect a few of those community members to the PMC to keep it viable.
If that does not happen, the Board can "reboot" a PMC by re-establishing it with a new or modified PMC. As an example, see the Board resolution to reboot the Apache Xalan PMC from the February 2019 Board minutes.
Mature or very slow-running projects should periodically (we recommend once a year) do a PMC roll call to confirm their viability.
In summary, the only reason for a project to move to the Attic is lack of oversight due to an insufficient number of active PMC members.
Note that going to the Attic is not necessarily a bad thing: it's merely a reflection that there isn't currently an active community to manage the project. It's also a clear way so set the right expectations for users of the project's code.
The Board sometimes asks for a roll call for projects that fail to report regularly, have very little visible activity on their mailing lists or releases, or do not seem to be responsive to security issues.
If a Director (on behalf of the Board) asks a PMC to perform a roll call, the PMC must respond by showing via an email thread that at least three PMC members are active.
A PMC can do this by each of its active members replying to a thread
board@, or having one PMC member send a link to a thread on the PMC's
lists where at least three PMC members reply that they are still monitoring
the project and could assist with creating new releases if needed. Be sure
to let the
board@ mailing list know when at least three PMC members have
responded (or always cc:
Projects must reply to the Board's request for a roll call. Failure to show that at least three PMC members are present before the next monthly Board meeting can lead to the Board concluding the project is due to shut down and move to the Apache Attic for lack of oversight.
See also why would a project move to the Attic, above.
Adding a new PMC member requires sending an email notification to the Board's mailing list and the PMC's private mailing list and waiting 72 hours. Be sure to send a separate [NOTICE] email for each individual you are nominating.
Once the notification appears in the archives, an invitation may be sent out 72 hours later (unless a Director objects to the nomination). The detailed process can be found in the June 2013 board minutes under section "7 G. Amend the Procedure for PMC Membership Changes".
Do NOT send an unconditional invite to the potential member before the 72 hour [NOTICE] period has expired! It would be very awkward if the invite has to be withdrawn if the board objects to it.
The PMC Chair, or any other PMC member can send this notification if they include a link to the formal PMC decision or a vote thread on their private@ list.
Ensure the PMC private list is copied - but do not Cc the potential member. For example:
To: firstname.lastname@example.org Cc: private@<project>.apache.org Subject: [NOTICE] Jane Doe for <project> PMC <project> proposes to invite Jane Doe (janedoe) to join the PMC.
If a vote was held, include
The vote result is available here: https://lists.apache.org/...
The link should be a permalink from the
https://lists.apache.org/ mail archive.
This allows any member to review the mail vote easily.
If the candidate does not (yet) have an Apache account, note that fact in the notification email.
Note: e-mail delivery can fail silently. It is vital that the PMC Chair checks the board archives to ensure that the NOTICE has actually been delivered to the board mailing list.
You can do this by sending a mail to the EZMLM server at
email@example.com followed by a
XXX = message number).
If the EZMLM server refuses the request, check that you are subscribed to the board@ list
ASF Members can also access the board archive.
It is not sufficient to check that you have seen the email; the email must appear in the archives.
After 72 hours have elapsed without objection, you may formally add the candidate to your PMC - the PMC Chair needs to:
The new PMC member should now subscribe to your PMC's private@ mailing list in the normal way.
Note that the appointment to the PMC does not become official until the Foundation's records (i.e. committee-info.txt) have been updated (see 7G (3) of the board minutes cited above).
If the candidate declines PMC membership or doesn't respond to the invitation, please follow up the original notice to the board to say that the change did not happen, and do not update the records.
The duration of the 72 hour waiting period is very important, not only in this context but also at a project level. People are in various timezones and have busy schedules. As with normal email, we need to provide time for people to respond. The ASF experience has shown that at least 72 hours is needed. We also need to follow defined procedures so that the ASF can operate according to its corporation status. The procedures and these FAQs should make it easy for everyone to operate efficiently.
New PMC members are required to read the PMC Branding Responsibilities.
"Resignation of a member of a PMC shall take effect immediately upon receipt of their resignation, as recorded on any of the Foundation's mailing list archives, but can be revoked by that member within 72 hours of receipt."
The detailed process can be found in the June 2013 board minutes under section 7 G. Amend the Procedure for PMC Membership Changes.
The ASF does not have any formal concept for an "emeritus PMC member" - an individual is either a member of the PMC or not. Projects are free to establish their own policies for designating members of the PMC who are inactive but remain on the PMC, or those who were formerly on the PMC and have resigned. Some projects have also established guidelines to allow former PMC members to remain on the private PMC list, and to allow a PMC member to request reinstatement simply by asking (note that the standard Board notification procedures must still be followed for reinstatement).
Once the PMC member's resignation is received on a mailing list of the Foundation, the resignation is considered effective. Hhowever, the PMC member has 72 hours to withdraw their resignation. Notifying the board is not required, but encouraged to ease tracking.
Once the resignation has taken effect, the PMC Chair should:
You can do these updates using the Whimsy roster.
Projects can establish their own policy on handling inactive members, as long as they apply it consistently. It is not a problem to retain members of the PMC who have become inactive, and it can make it easier for them to stay in touch with the project if they choose to become active again.
Typically, PMC members who are no longer able to participate will resign from the PMC. However, if a PMC chooses to remove one of its members (without that member's request or consent), it must request the Board to make that decision (which is typically done with a resolution at the Board's next meeting). The PMC chair should send an email to the board@ mailing list detailing the request for removal and the justification the PMC has for that removal, and copy the project's private@ list.
This is a tragic occurrence, but with so many communities here at the Foundation, it is bound to happen occasionally. Each community can decide how they want to handle this issue:
It is the responsibility of each project PMC to review productive contributors to their project and consider nominating those contributors as committers, and then voting them in as committers (and possibly PMC members as well). PMCs should be guiding their new committers, to make sure that they have access to the proper resources and ASF documentation (e.g. the Guide for new committers or the Committers' FAQ ). If a productive individual is already an Apache committer on another project, you can just grant them karma to your project instead.
Most PMCs hold formal votes on committer nominees to decide to invite them, although PMCs are free to follow their own documented process for finding consensus on adding new committers.
Once the PMC formally wants to invite an individual to be a committer,
you should then invite the person, and require the new committer to
submit an Individual Contributor License Agreement (ICLA) to the secretary.
The secretary cannot process new committer accounts without receiving the CLA acknowledged by the ASF secretary or
a board member. Your PMC needs to work with the new committer to ensure
that their CLA is received and recorded properly, so you need to monitor
the file iclas.txt in the
foundation/officers repository. Only ASF
members and officers (PMC chairs) have access. The Apache Phone Book
has an Unlisted CLAs page
which is generated daily from the iclas.txt file, and recently received CLAs
Encourage your new committer to include both the PMC name and their desired account ID
on the submitted ICLA. If both of these pieces of information are provided on the ICLA
form; and the ICLA is sent to the correct address (
firstname.lastname@example.org), and the secretary
or assistant can verify a [VOTE][RESULT] for the new committer, the account will be requested
by the person (secretary or assistant) filing the ICLA.
If the new account information is not provided on the ICLA, the PMC chair is responsible to get the new committer's desired account ID and request the new account.
Once the ICLA has been filed, use the ASF New Account Request form to generate the request. Should the PMC chair be unavailable for any reason, any ASF member can act his/her stead.
For incubating projects: If
then the secretary or assistant will request the account. In other cases, the Mentors will request the account. If the podling you're requesting accounts for doesn't appear in the drop-down list of podlings, provide the podling name in the free text input box.
Most PMCs decide on new committers through an election process on their private mailing list. Please include a URL or message-id reference to the final vote tally using the Apache Mail Archives.
New account requests will only be accepted from PMC chairs and ASF members. If you are acting on behalf of a project which was accepted for incubation, please get in touch with the sponsoring PMC and let them take care of requesting any new accounts.
The request will be CC'd to the PMC mailing list. Barring objections from the PMC, the infrastructure team will create the account and assign the appropriate group permissions. This may take a few days. A message confirming the new account will be sent to the PMC mailing list and to the new committer.
If the ICLA included the PMC name, normally the account will already have been set up in the correct LDAP group that will grant access to the project source repository.
If not, the PMC takes over and provides the rest of the infrastructure needs. In particular, the PMC chair has the ability to - and the responsibility for - providing write access to the project's source repository.
For most operations, PMCs do not need to do anything to grant new committers SVN access to their areas. However, if the automatic LDAP process does not work for some reason, the PMC can use the ASF authorization template.
The [groups] section of the file defines SVN group names and their members. The groups are defined as LDAP references; see below for how to update them.
To grant or deny access to directories in SVN, the PMC chair needs to update the appropriate [group] entry. The PMC chair has access to make changes to the project groups held in LDAP.
PMC Chairs (only) may use the Whimsy roster tool, navigate to the committee, and either double click on the person or the plus sign to modify or add a person.
Podling authorization is managed using LDAP groups, just like PMCs - please use Whimsy Roster tool to update.
In this case, please contact your PMC first. All PMC chairs can give an existing Apache ID access to their project's repositories. See how-to above. For podlings, the PMC is the Incubator.
Chairs may use Whimsy's roster tool to modify their project membership lists.
ONLY if a PMC chair is not responsive or unavailable, then contact the Apache Infra team for assistance. This should only be for people who already have an Apache account and need extended commit access.
Karma request form: To: infrastructure Cc: private@<project>.apache.org, email@example.com Subject: Karma request Userid: ... Requested karma: <project>[/<subproject>]... Reason: [a few lines explaining why someone needs karma] [Vote: reference to mail archive for PMC bookkeeping]
Once the request has been received, a person with appropriate access will extend the karma and reply accordingly.
Most committers can access all needed resources with just their Apache ID and their project's repositories and mailing lists. But if you do need access to other official ASF servers, request an account by contacting the Apache Infra team.
Account request form: To: infrastructure Cc: private@<project>.apache.org, firstname.lastname@example.org Subject: Machine account request - <machine> Userid: ... Machine: ... Groups required:... Reason: [a few lines explaining why an account is required] [Vote: reference to mail archive for PMC bookkeeping]
The administrator of the machine will then reply accordingly.
If the code to be imported is licensed under a Category A license and the intent is to distribute the code under its original license, copy the code into the Apache source repository, preserving its original header. Add the license for the code to the top level LICENSE file. If the team makes changes to the code, add an Apache header to the file(s) that notes the changes.
If the code to be imported is intended to have continued development in Apache, and the owners of the code are willing to contribute their Intellectual Property to Apache under an Individual Contributor License Agreement, Corporate Contributor License Agreement, or Software Grant Agreement, you can copy the code to the Apache repository, changing the license header to the standard Apache header. In this case, the code needs to be reviewed by the Incubator via the Intellectual Property Clearance process.
There are a number of Apache lists whose archives are not available to the public. Posts to these lists are considered confidential. Do not quote them on public lists our outside the ASF without the permission of the author.
PMC members may search archives of their project's private@ list. ASF members and officers may also read PMC mailing list archives. There are several ways to access our private archives:
-getadministrative command to ezmlm to download groups of mails.
All PMC members of a project should be subscribed to their project's
list. In addition, ASF Members may read any project's private list. In general,
people not on a PMC should not be allowed to subscribe to
private@ lists unless they are ASF Members.
You can self-subscribe to mailing lists.
There are two main ways to check the membership of PMCs and LDAP groups:
Please allow time for any changes to LDAP and committee-info.txt to propagate to the Phonebook app.
Note: The official record for PMC membership is the committee-info.txt file, and not the LDAP committee group.
See the Contact Infra roadmap to request these and other resources for your project.
In almost all cases, project business should happen on that project's publicly archived mailing lists - the detailed policy explains the few exceptions.
Any topic which does not specifically need to be private should be discussed on an appropriate public mailing list. This allows the public to read about the direction of the project and to offer early feedback.
Most projects do their work on their email@example.com mailing list. Some projects also have a user@ mailing lists for more general or non-technical questions, and may have a general@ mailing list. Every project should have a clear mailing lists page that has instructions for subscribing to their lists and for reading the archives.
Normally, Apache projects are expected to self-manage their affairs; the people on a PMC and regular committers typically know the best way to work within their project communities. However, if things don't work well, or the project community has serious policy questions or disagreements about how to work together, you can ask for help elsewhere around the ASF.
The detailed Escalation Guide
helps communities figure out where to get help from other groups at Apache,
or, if all else fails, to ask for help or appeal issues to the Board.
The Apache Organizational Chart can help find the right officer or group to ask for help on most issues, like legal, branding, press, or the many other services the ASF offers projects.
