The nine-person legal governing body of the ASF, elected by the
members. The board provides the oversight of the
Foundation's activities and operation, and has the responsibility of
applying and enforcing the ASF's bylaws. Among other
things, the board approves or rejects resolutions brought before it,
such as for the creation or dissolution of ASF projects ,
funding requests, legal concerns, and disciplinary actions. As an open
and non-profit corporation, the minutes of the board's meetings are
publicly available at
These minutes include all decisions not made in executive
session. Also see Director.
Arguing (pointlessly) about which color to paint the bikeshed. As
explained here it
may happen when the argument is so trivial that it's easy for anyone
to have an opinion, and want to see theirs prevail.
A Build is a package which is not suitable for distribution to the
general public. They are works-in-progress, and as such the only
people builds should be offered to are other people working on product
development at the foundation.
Bylaws are a codification of the rules that some organisation follows.
Some, such as the ASF
bylaws, are legally
binding and have significance outside the organisation. Others, such
as the Jakarta
bylaws, are only
meaningful within the community and are only as binding
as the community itself makes them. The bylaws of an organisation
within the ASF may not contradict those of the ASF proper; any such
conflicting parts in the organisation bylaws are necessarily null and
1. The Chair of the Board of Directors of
the ASF , responsible for the orderly meeting and functioning
of the Board.
2. The official head of a committee, such as a
Project Management Committee PMC. PMC Chairs are
Vice Presidents given charge of the proper operation of their
ASF projects collaborate on code using version
control software to coordinate changes.
The ability to make direct changes to that code is known as commit
access (from the [VCS] commit subcommand). This process patches the
actual official code. Also see Karma .
(Often abbreviated 'CTR' or 'C-T-R'.) A policy governing code changes
which permits developers to make changes at will, with the possibility
of being retroactively vetoed. C-T-R is an application of
decision making through lazy consensus. The C-T-R
model is useful in rapid-prototyping environments, but because of the
lack of mandatory review it may permit more bugs through in daily practice than the
R-T-C alternative. Compare R-T-C
, and see the description of the voting process.
Someone who makes consistent improvements to the entities under an
ASFPMC , either code or documentation or otherwise.
This does not, in and of itself, imply commit access
, though frequent and valued contributors are readily voted
on for such access.
Contributor License Agreement (CLA) is sometimes referred to as
Individual Contributor License Agreement (ICLA). There is also a
Corporate Contributor License Agreement (CCLA). All are explained on
the Licenses page.
A user who contributes to a project in the form of code or
documentation becomes a developer. They take extra steps to
participate in a project, are active on the developer mailing list,
participate in discussions, provide patches, documentation,
suggestions, and criticism. Developers are also known as
One of nine individuals elected annually by the members to the
Foundation's board of directors. Directors may or may not
have individual responsibilities, but all are generally expected to
stay informed about as much of the Foundation's operations and
activity as possible, since the Board provides oversight for the
Foundation as a whole.
A term used to formally designate someone as no longer active, but
still entitled to many of the rights and privileges of the position.
For example, an ASF member who hasn't attended any membership meetings
for a long time is declared emeritus; someone who no longer has time
to work on a particular project may declare itself
emeritus. Emeritus status indicates interest but not activity, as
opposed to having resigned.
A portion of a board meeting which concerns confidential
matters and which therefore cannot be publicly minuted. Examples
include salary discussions, areas covered by non-disclosure
agreements, disciplinary actions, and some types of funding decisions.
Informal event at which ASF participants can get together, network,
and discuss/argue/hack/prototype according to their interests.
Hackathons are open to all committers and invited
contributors, and typically take place immediately preceding or
following the ApacheCon events.
1. Sufficient access to perform an operation, such as committing
changes to a version control. ("Please grant Yo
Mega karma to the foo-bar.")
2. Respect and merit in
the community. ("Al Faa has good karma because of the
careful and tactful way he makes his points and the quality of his
3. Any combination of senses 1 and two; they are indirectly related.
(Also called 'lazy approval'.) A decision-making policy which assumes
general consent if no responses are posted within a defined period.
For example, "I'm going to commit this by lazy consensus if no-one
objects within the next three days." Also see Consensus Approval ,
Majority Approval , and the description of the voting
Refers to a vote (sense 1) which has completed with at
least three binding +1 votes and more +1 votes than -1 votes. (
I.e. , a simple majority with a minimum quorum of three positive
votes.) Note that in votes requiring majority approval a -1 vote is
simply a vote against, not a veto. Compare
Consensus Approval. See also the description of the voting
An individual who has been elected to membership in the ASF by the
existing members. Membership benefits include having a voice in
the functioning of the Foundation, the ability to nominate and vote
on new Member candidates and on directors.
The concept of 'merit' is central to the Apache philosophy and
community methodology. Merit is a qualitative and
subjective term, referring essentially to attributes such as those
below; however, it can probably be summed up as the combination of the
worth of one's accomplishments and the respect of one's
- technical competence
- ability to get along with others
- positive contributions to discussions and code
The acquisition of merit is a cumulative process;
once acquired, it doesn't decay. It is possible to lose merit, though,
by violating the community ethics, guidelines, or sensibilities.
Meritocracy is one of the principles underlying the ASF and its
philosophy. As it has been put, 'the more you do the more you are
allowed to do.' As a person acquires merit, his or her stature in the
community grows, and (to a certain extent) the weight
given to his or her opinions.
Netiquette is the term applied to the common rules of good online
behaviour. For the general case, it is defined in IETF RFC
1855 ; for the more specific
Apache environment, it boils down to things like:
- don't flame
- lurk for a while after joining a list before
posting; this allows you to get a feel for the personalities,
attitudes, and issues, as well as existing rules for acceptable
- be aware of the project 's/list's
guidelines (such as on voting), and don't violate them
- if you have a question, search the list archives and the bug database
before asking what may have already been answered>
are just the rough outline of things that may be more (or less) the
rule on a per -list basis. They boil down to 'be polite' and 'don't
make unnecessary work for others'.

Package (sometimes referred to informally as Tarball or Distribution)¶
A Package is a compressed archive file created from a project's
source code with the intent to distribute. Packages are typically either
source packages or binary packages built from source; sometimes separate
documentation packages are released alongside the source package. Often
packages have have external dependencies which may require additional
software be installed as a prerequisite.
Project Management Committee, the group of people with formal
oversight of a project. The chair of a PMC is always an
officer of the Foundation. As the PMC has official
oversight responsibilities assigned by the Board , its
actions are considered to be on behalf of the Foundation, with all the
legal protections and responsibilities implied. See the
(Often referenced as 'RTC' or 'R-T-C'.) Commit policy which requires
that all changes receive consensus approval in
order to be committed. Compare C-T-R , and see the
description of the voting process.
In the Apache environment, some communities may decide to permit (or
encourage) revolutions as ways of reconciling differences,
particularly code changes which have been blocked on a particular
branch by a veto. Originally described by James Duncan Davison in his
'Rules for Revolutionaries,' the concept has been adopted, formally or
informally, by at least one Apache project. Essentially, a
revolution occurs when a group of committers decides to fork the
current main branch in order to work on problematic code or concepts.
This permits them to pursue it without disturbing the evolutionary
work on the main branch. A revolutionary branch may eventually be
merged back into the main branch, die out, split completely and become
a new main branch, or may absorb the current main branch into itself
(essentially no different than the first option). See the ' Rules for
' and compare Evolution.
Due to the noninteractive style of communication practised by most of
the Apache development projects, maintaining a record of decisions
made -- and in progress -- can be a useful thing. A number of the
Apache projects accomplish this through the use of a file, typically
named STATUS , stored in the project's own code repository. In
addition to keeping existing developers informed of current issues,
such files also provide useful information to new would-be developers
investigating the project.
The treasurer of the ASF is an officer of the
corporation, and is responsible for managing the funds and assets of
the Foundation, reporting tax information, and so on. The treasurer
need not be a member of the Foundation, nor a
director , though the role is often filled by someone who
Someone that uses our software. Users contribute to the Apache
projects by providing feedback to developers in the form of bug
reports and feature suggestions. Users participate in the Apache
community by helping other users on mailing lists and user support
Version control systems provide the ability to track (and potentially
revert) incremental changes to files, reporting them to a mailing list
as they are made, and can be used concurrently by many developers. All
of the Foundation's code and documentation are managed in such systems
thus providing a complete history for each codebase. See
subversion and CVS
According to the Apache methodology, a change which has been made or
proposed may be made moot through the exercise of a veto by a
committer to the codebase in question. If the
R-T-C commit policy is in effect, a veto prevents
the change from being made. In either the R-T-C or
C-T-R environments, a veto applied to a change
that has already been made forces it to be reverted. Vetos may not be
overridden nor voted down, and only cease to apply when the committer
who issued the veto withdraws it. All vetos must be accompanied by a
valid technical justification; a veto without such a justification is
invalid; in case of doubt, deciding whether a technical
justification is valid is up to the PMC. Vetos force discussion
and, if supported, version control rollback or appropriate code changes. Vetoed code commits
are best reverted by the original committer, unless an urgent
solution is needed (e.g., build breakers). Vetos only apply to
code changes; they do not apply to
procedural issues such as software releases.
ASF vice-presidents are officers of the
corporation, with authority over and responsibility for specific
areas of the Foundation's work. PMCchairs are
vice-presidents given charge of the proper operation of their
1. The process of making a formal decision. ('The vote for foo
will close in three days.') 2. The expression of a positive or
negative opinion, or a veto, as part of a formal decision. ('My vote
is -1 because foo smells bad.') Binding votes are those
cast by the PMC committers for the project to which the
decision applies. Votes cast by others are advisory or indicative
only. See also ConsensusApproval , MajorityApproval
, LazyConsensus , and the description of the voting
