Maturity Model Assessment
...
Mentors and community members are encouraged to contribute to this page and comment on it. The following table summarizes the project’s self-assessment against the Apache Maturity Model.
| ID | Description | Status |
|---|---|---|
| Code | ||
| CD10 | The project produces Open Source software, for distribution to the public at no charge. | YES. The project source code is licensed under the Apache License, version 2.0. |
| CD20 | The project's code is easily discoverable and publicly accessible. | YES. Linked from the website, which has links to our GitHub projects. |
| CD30 | The code can be built in a reproducible way using widely available standard tools. | YES. We use Apache Maven, the most widely used build tool in the Java ecosystem. We have documentation in our repos about builds and contributing. |
| 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. Using Git for source code, document, and website. All the repositories are in GitHub, releases are cut from that repository. All releases are tagged. |
| 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. The project uses the git repository, managed by Apache Infra, ensuring provenance of each line of code to a committer. Third-party contributions are accepted in accordance with the code submit guide only. |
| Licenses and Copyright | ||
| LC10 | The code is released under the Apache License, version 2.0. | YES. There is a small amount of third-party libraries used in our code base, and we include details in our licenses. |
| LC20 | Libraries that are mandatory dependencies of the project's code do not create more restrictions than the Apache License does. | YES. The list of mandatory dependencies has been reviewed to contain approved licenses only. |
| LC30 | The libraries mentioned in LC20 are available as Open Source software. | YES. All dependencies are OSS. |
| 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. The project uses a repository managed by Apache Gitbox -- write access requires an Apache Foundation LDAP account, which requires an ICLA on file. |
| LC50 | The copyright ownership of everything that the project produces is clearly defined and documented. | YES. All files in the source repository have appropriate headers. |
| 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. Source releases are distributed via dist.apache.org and linked from the website. |
| RE20 | Releases are approved by the project's PMC, in order to make them an act of the Foundation. | YES. All incubating releases have been unanimously approved by the Apache StormCrawler community and the Incubator, all with at least 3 (P)PMC votes. |
| RE30 | Releases are signed and/or distributed along with digests that can be reliably used to validate the downloaded archives. | YES. All releases are signed, and the KEYS file is provided on dist.apache.org. |
| 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. Convenience binaries are distributed via Maven Central Repository. |
| RE50 | The release process is documented and repeatable to the extent that someone new to the project is able to independently generate the complete set of artifacts required for a release. | YES. A release guide is available describing the entire process. The StormCrawler releases have been performed by two different release managers. |
| 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. The project records all bugs in our GitHub repository issue trackers. |
| QU20 | The project puts a very high priority on producing secure software. | YES. Security issues are treated with the highest priority, according to the CVE/Security Advisory procedure. |
| QU30 | The project provides a well-documented channel to report security issues, along with a documented way of responding to them. | YES. Website provides a security link. Our GitHub projects also point to the standard ASF policy. |
| 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. The project aims to make no backward-incompatible changes within a given major version. |
| QU50 | The project strives to respond to documented bug reports in a timely manner. | YES. The project has merged a few bugs since incubation but has been existing for over 10 years now and is pretty stable and mature. |
| Community | ||
| CO10 | The project has a well-known homepage that points to all the information required to operate according to this maturity model. | YES. Each GitHub repo has its own CONTRIBUTING.md and contact details in README.md. |
| CO20 | The community welcomes contributions from anyone who acts in good faith and in a respectful manner and adds value to the project. | YES. It’s part of the contribution guides, and the current committers are keen to welcome contributions. |
| CO30 | Contributions include not only source code, but also documentation, constructive bug reports, constructive discussions, marketing, and anything that adds value to the project. | YES. The contribution guides refer to non-source code contributions, like documentation. |
| CO40 | The community is meritocratic and over time aims to give more rights and responsibilities to contributors who add value to the project. | YES. The community has elected one new committer and one PPMC member during incubation. |
| 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. The PPMC consists of experienced committers and PMC members from other TLPs. The barrier to entry is not documented but well understood. We do not aim to act as gate keepers and are happy for new faces. |
| CO60 | The community operates based on consensus of its members who have decision power. Dictators, benevolent or not, are not welcome in Apache projects. | YES. The project works to build consensus. |
| CO70 | The project strives to answer user questions in a timely manner. | YES. We have mailing lists, but most external user interaction seems to happen via GitHub Discussions. |
| 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: https://stormcrawler.apache.org/contribute/ |
| 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. The project has been making important decisions on the project mailing lists. Vast majority of, if not all, decisions have had a consensus without any PPMC action needed. |
| CS30 | Documented voting rules are used to build consensus when discussion is not sufficient. | YES. The project uses the standard ASF voting rules. Voting rules are clearly stated before the voting starts for each individual vote. |
| 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. The project hasn’t used a veto at any point and relies on robust code reviews. |
| 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. The project has been making important decisions on the project mailing lists. Minor decisions may occasionally happen during code reviews, which are also asynchronous and in written form. |
| Independence | ||
| IN10 | The project is independent from any corporate or organizational influence. | YES. The project team gathers people from different companies. |
| IN20 | Contributors act as themselves as opposed to representatives of a corporation or organization. | YES. The committers and contributors act on their own initiative without representing a corporation or organization. |
