Currently, this document is working in progress.
Code
CD10
The project produces Open Source software, for distribution to the public at no charge.
Yes
Zeppelin uses the standard apache distribution methods. Source and release packages are always available at no charge on download page.
CD20
The project's code is easily discoverable and publicly accessible.
Yes
Source code is available on git repository as well as on the mirror. Github mirror is provided for convenience.
CD30
The code can be built in a reproducible way using widely available standard tools.
Yes
Zeppelin can be built by Apache Maven and procedure is documented in README.md.
CD40
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.
Yes
git provides full history of the code. Each released version has corresponding tag (e.g. vX.Y.Z) that allows recreating any released version.
CD50
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.
Yes
Only Committers have write access to git repository. We recommend that every contribution contains enough informations in pull request description. When code is merged, the merge script automatically includes author's informations, each commit hash and message as well as pull request description into commit message.
Licenses and Copyright
LC10
The code is released under the Apache License, version 2.0.
Yes
LC20
Libraries that are mandatory dependencies of the project's code do not create more restrictions than the Apache License does.
Yes
LC30
The libraries mentioned in LC20 are available as Open Source software.
Yes
LC40
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.
Yes
LC50
The copyright ownership of everything that the project produces is clearly defined and documented.
Yes
We provide LICENSE and NOTICE file for source release. As well as LICENSE and NOTICE for binary package
Releases
RE10
Releases consist of source code, distributed using standard and open archive formats that are expected to stay readable in the long term.
Yes
Released source code is available through https://dist.apache.org/repos/dist/release/incubator/zeppelin in tgz format.
RE20
Releases are approved by the project's PMC (see CS10), in order to make them an act of the Foundation.
Yes
Every release is approved by Incubator PMC. (while Zeppelin is in incubation, approval of PPMC is recommendation)
RE30
Releases are signed and/or distributed along with digests that can be reliably used to validate the downloaded archives.
Yes
Release are provided with KEYS and digests in download page for validation.
RE40
Convenience binaries can be distributed alongside source code but they are not Apache Releases -- they are just a convenience provided with no guarantee.
Yes
Quality
QU10
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.
Yes
QU20
The project puts a very high priority on producing secure software.
Yes
QU30
The project provides a well-documented channel to report security issues, along with a documented way of responding to them.
No
We don't have communication channel dedicated to security issue.
QU40
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.
Yes
QU50
The project strives to respond to documented bug reports in a timely manner.
Yes
Community
CO10
The project has a well-known homepage that points to all the information required to operate according to this maturity model.
Yes
Project has http://zeppelin.incubator.apache.org/ that points all informations.
CO20
The community welcomes contributions from anyone who acts in good faith and in a respectful manner and adds value to the project.
Yes
CO30
Contributions include not only source code, but also documentation, constructive bug reports, constructive discussions, marketing and generally anything that adds value to the project.
Yes
CO40
The community is meritocratic and over time aims to give more rights and responsibilities to contributors who add value to the project.
Yes
CO50
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.
Yes
CO60
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.
Yes
CO70
The project strives to answer user questions in a timely manner.
Yes
Consensus Building
CS10
The project maintains a public list of its contributors who have decision power -- the project's PMC (Project Management Committee) consists of those contributors.
Yes
We maintain the list of Committers in the project incubation status page.
CS20
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.
Yes
CS30
Documented voting rules are used to build consensus when discussion is not sufficient.
Yes
Documented voting rules are used for code commit.
CS40
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.
Yes
CS50
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.
Yes
