 DescriptionStatus

Code

CD10The project produces Open Source software, for distribution to the public at no charge. 1 
CD20The project's code is easily discoverable and publicly accessible. 
CD30The code can be built in a reproducible way using widely available standard tools. 
CD40The full history of the project's code is available via a source code control system, in a way that allows any released version to be recreated. 
CD50
 

Licenses and Copyright

LC10The code is released under the Apache License, version 2.0. 
LC20Libraries that are mandatory dependencies of the project's code do not create more restrictions than the Apache License does. 3 4 
LC30The libraries mentioned in LC20 are available as Open Source software. 
LC40Committers are bound by an Individual Contributor Agreement (the "Apache iCLA") that defines which code they are allowed to commit and how they need to identify code that is not their own. 
LC50The copyright ownership of everything that the project produces is clearly defined and documented. 5 

Releases

RE10Releases consist of source code, distributed using standard and open archive formats that are expected to stay readable in the long term. 6 
RE20Releases are approved by the project's PMC (see CS10), in order to make them an act of the Foundation. 
RE30Releases are signed and/or distributed along with digests that can be reliably used to validate the downloaded archives. 
RE40Convenience binaries can be distributed alongside source code but they are not Apache Releases -- they are just a convenience provided with no guarantee. 

Quality

QU10The project is open and honest about the quality of its code. Various levels of quality and maturity for various modules are natural and acceptable as long as they are clearly communicated. 
QU20The project puts a very high priority on producing secure software. 7 
QU30The project provides a well-documented channel to report security issues, along with a documented way of responding to them. 8 
QU40The project puts a high priority on backwards compatibility and aims to document any incompatible changes and provide tools and documentation to help users transition to new features. 
QU50The project strives to respond to documented bug reports in a timely manner. 

Community

CO10The project has a well-known homepage that points to all the information required to operate according to this maturity model. 
CO20The community welcomes contributions from anyone who acts in good faith and in a respectful manner and adds value to the project. 
CO30Contributions include not only source code, but also documentation, constructive bug reports, constructive discussions, marketing and generally anything that adds value to the project. 
CO40The community is meritocratic and over time aims to give more rights and responsibilities to contributors who add value to the project. 
CO50The way in which contributors can be granted more rights such as commit access or decision power is clearly documented and is the same for all contributors. 
CO60The community operates based on consensus of its members (see CS10) who have decision power. Dictators, benevolent or not, are not welcome in Apache projects. 
CO70The project strives to answer user questions in a timely manner. 

Consensus Building

CS10The project maintains a public list of its contributors who have decision power -- the project's PMC (Project Management Committee) consists of those contributors. 
CS20Decisions are made by consensus among PMC members 9 and are documented on the project's main communications channel. Community opinions are taken into account but the PMC has the final word if needed. 
CS30Documented voting rules are used to build consensus when discussion is not sufficient. 10 
CS40In Apache projects, vetoes are only valid for code commits and are justified by a technical explanation, as per the Apache voting rules defined in CS30. 
CS50All "important" discussions happen asynchronously in written form on the project's main communications channel. Offline, face-to-face or private discussions 11 that affect the project are also documented on that channel. 

Independence

IN10The project is independent from any corporate or organizational influence. 12 
IN20Contributors act as themselves as opposed to representatives of a corporation or organization.

Footnotes

  1.  "For distribution to the public at no charge" is straight from the from the ASF Bylaws at http://apache.org/foundation/bylaws.html. (1)
  2.  See also LC40. (2)
  3.  It's ok for platforms (like a runtime used to execute our code) to have different licenses as long as they don't impose reciprocal licensing on what we are distributing. (3)
  4.  http://apache.org/legal/resolved.html has information about acceptable licenses for third-party dependencies (4)
  5.  In Apache projects, the ASF owns the copyright for the collective work, i.e. the project's releases. Contributors retain copyright on their contributions but grant the ASF a perpetual copyright license for them. (5)
  6.  See http://www.apache.org/dev/release.html for more info on Apache releases (6)
  7.  The required level of security depends on the software's intended uses, of course. Expectations should be clearly documented. (7)
  8.  Apache projects can just point to http://www.apache.org/security/ or use their own security contacts page, which should also point to that. (8)
  9.  In Apache projects, "consensus" means widespread agreement among people who have decision power. It does not necessarily mean "unanimity". (9)
  10.  For Apache projects, http://www.apache.org/foundation/voting.html defines the voting rules. (10)
  11.  Apache projects have a private mailing list that their PMC is expected to use only when really needed. The private list is typically used for discussions about people, for example to discuss and to vote on PMC candidates privately. (11)
  12.  Independence can be understood as basing the project's decisions on the open discussions that happen on the project's main communications channel, with no hidden agendas. (12)
