The Hyperledger Project has defined a lifecycle for its projects but this definition does not specify in any detail what it takes for a project to be able to transition from the Incubation phase to the Active phase.
For this reason this document defines two sets of exit criteria. The first one is made of requirements expected to be met by all projects before moving to Active. The second set lists examples of additional requirements typically defined at the onset of the project as goals to be met to exit incubation. There are expected to be documented in the Proposal for a Hyperledger Improvement Project (HIP). Because not all projects have the same goals, the importance of each criteria and the exact definition of this second set of criteria may vary from one project to another. Ultimately the TSC is responsible for determining whether a project deserves to move to Active or not and this decision does not need to be solely based on these exit criteria. The purpose of these exit criteria is to help the TSC in its decision process by informing its members of key aspects of the project.
All code has been made available under the Apache License and is free of incompatible dependencies
Project name has been checked for trademark issues
The project must have an active and diverse set of contributing members representing various constituencies
The project is not highly dependent on any single contributor (there are at least 3 legally independent committers and there is no single company or entity that is vital to the success of the project)
Release plans are developed and executed in public by the community.
Sufficient test coverage
The project must include a comprehensive unit and integration test suite and document its coverage. Additional performance and scale test capability is desirable.
Sufficient user documentation
The project must including enough documentation for anyone to test or deploy any of the modules.
The project must document what requirements and use cases it addresses.
The project must document how it fits within the Hyperledger Architecture
Compatibility with other Hyperledger projects
Where applicable, the project should be compatible with other active projects.
Release numbering: the project should use the Hyperledger standard release taxonomy, once that is agreed upon.
Project must make a release, even a “developer preview”, before graduation.
Gerrit or Github repo has been created
Mailing lists have been created and are archived
Other communication means used, such as slack channels, are set up
Project is set up with Continuous Integration
All information necessary for someone to join the community and be able to start contributing is duly documented (location of repo, list of maintainers, mailing lists addresses, slack channels if used, etc) following the Hyperledger Project standard practice (CONTRIBUTING.md, MAINTAINERS.txt, etc)
A team seeking to graduate from incubation shall have started the CII Badge application and be nearly complete with incomplete badge requirements referenced in their graduation proposal. 100% of the applicable criteria for the CII Badge is a requirement for releasing a 1.0 of the project. That does not mean the project must have 100% of all criteria, just 100% of the applicable criteria. This is to allow for projects such as test harnesses, that have “N/A” answers for questions that don't offer that as an option.
