This is an assessment of the Unomi podling’s maturity, meant to help inform the decision (of the mentors, community, Incubator PMC and ASF Board of Directors) to graduate it as a top-level Apache project.

It is based on the ASF project maturity model at https://community.apache.org/apache-way/apache-project-maturity-model.html

Maintaining such a file is a new, experimental idea as part of the continuous improvement of the ASF incubation process. Unomi is the second podling where that happens.

Overall assessment

Just introduced this report card, we will need to evaluate all the model’s parts to see how we fare so far.

Maturity model assessment

Mentors and community members are encouraged to contribute to this and comment on it.



The project produces Open Source software, for distribution to the public at no charge.

  • [ OK ] : everything is hosted at the Apache Software Foundation


The project’s code is easily discoverable and publicly accessible.

  • [ OK ] : it is linked from the main project site and accessible in the public ASF git repository


The code can be built in a reproducible way using widely available standard tools.

  • [ OK ] : Jenkins is configured on the project.


The 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.

  • [ OK ] : everything is in the ASF Git repository.


The provenance of each line of code is established via the source code control system, in a reliable way based on strong authentication of the committer. When third-party contributions are committed, commit messages provide reliable information about the code provenance.

  • [ OK ] : Only ASF committers with CLAs may contribute to the project.


_The code is released under the Apache License, version 2.0.

  • [ OK ] : A LICENSE file is also at the root of the ASF Git repository


Libraries that are mandatory dependencies of the project’s code do not create more restrictions than the Apache License does.

  • [ OK ] : NOTICE files contain all the information and has been reviewed on two releases already


The libraries mentioned in LC20 are available as Open Source software.

  • [ OK ] : See LC20


Committers 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.

  • [ OK ] : All committers have registered iCLAs


The copyright ownership of everything that the project produces is clearly defined and documented.

  • [ ] : to be evaluated



Releases consist of source code, distributed using standard and open archive formats that are expected to stay readable in the long term.

  • [ OK ] : Two releases have been produced so far and have been reviewed by IPMCs


Releases are approved by the project’s PMC (see CS10), in order to make them an act of the Foundation.

  • [ OK ] : Happened for two major releases already


Releases are signed and/or distributed along with digests that can be reliably used to validate the downloaded archives.

  • [ OK ] : See releases here


Convenience binaries can be distributed alongside source code but they are not Apache Releases – they are just a convenience provided with no guarantee.

  • [ OK ] : See the releases here



The 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.

  • [ ] : to be evaluated


The project puts a very high priority on producing secure software.

  • [ ] : to be evaluated


The project provides a well-documented channel to report security issues, along with a documented way of responding to them.

  • [ ] : to be evaluated


The 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.

  • [ ] : to be evaluated


The project strives to respond to documented bug reports in a timely manner.

  • [ ] : to be evaluated



The project has a well-known homepage that points to all the information required to operate according to this maturity model.


The community welcomes contributions from anyone who acts in good faith and in a respectful manner and adds value to the project.

  • [ ] : to be evaluated


Contributions include not only source code, but also documentation, constructive bug reports, constructive discussions, marketing and generally anything that adds value to the project.

  • [ ] : to be evaluated


The community is meritocratic and over time aims to give more rights and responsibilities to contributors who add value to the project.

  • [ ] : to be evaluated


The 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.

  • [ ] : to be evaluated


The community operates based on consensus of its members (see CS10) who have decision power. Dictators, benevolent or not, are not welcome in Apache projects.

  • [ ] : to be evaluated


The project strives to answer user questions in a timely manner.

  • [ ] : to be evaluated

Consensus Building


The project maintains a public list of its contributors who have decision power – the project’s PMC (Project Management Committee) consists of those contributors.

  • [ ] : to be evaluated


Decisions are made by consensus among PMC members 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.

  • [ ] : to be evaluated


Documented voting rules are used to build consensus when discussion is not sufficient.

  • [ ] : to be evaluated


In 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.

  • [ ] : to be evaluated


All “important” discussions happen asynchronously in written form on the project’s main communications channel. Offline, face-to-face or private discussions that affect the project are also documented on that channel.

  • [ ] : to be evaluated



The project is independent from any corporate or organizational influence.

  • [ ] : to be evaluated


Contributors act as themselves as opposed to representatives of a corporation or organization.

  • [ ] : to be evaluated
