Deputy Project Leaders#
The Release Manager (RM) is appointed for a minor version (A.B.x) release series of Matplotlib rather than for a fixed term. They are responsible for the full release life cycle of all minor releases in the series including:
ensuring the whats new, API changes, and release notes are up to date
the timing of the releases
what changes should or should not be backported from the master branch
rebuilding and publishing the website
publishing sdist and wheels to pypi
notifying down-stream packagers of the release
announcing the release (in coordination with the Community Manager)
An individual may be the RM for more than one release series at the same time.
A good API is essential for usability and user satisfaction. We strive for an API that is intuitive, easy to use, consistent and stable. The API Leader (AL) is responsible for the overall evolution of the API. In particular they ensure that:
additions are justified, i.e. they do not duplicate existing functionality and do not exceed the intended scope of the library
additions are consistent with the existing API
additions are designed to not cause any future liabilities, i.e. they do not unintendedly limit future extensions or expose internals
changes are carefully balanced between their benefit for future users and their impact on existing code
changes follow the deprecation policy so that they do not hit users unprepeared
Matplotlib relies on a wide and deep code base to implement its public API; the low-level details need to be correct to faithfully implement that API. In contrast to the API Leader, who is responsible for what the library does, the Principal Engineer is responsible for how. They are the point of contact for:
integration with GUI toolkits
internal data structures and API
Reference Documentation Leader#
The Matplotlib API reference documentation is split between the docstrings and the rst source. This documentation needs to be complete and accurate as our users rely on it as the final authority of what a given method will do (short of reading the source).
The Reference Documentation Leader (RDL) is responsible for ensuring that the docstrings are:
correctly formatted and render as intended
In addition to the docstrings the RDL is responsible for the sphinx build machinery and our sphinx extensions.
Narrative Documentation Leader#
In addition to the reference documentation, Matplotlib has narrative documentation. This documentation can take the form of short “cookbook” examples, longer tutorials, and prose documenting the how and why of the internals of the library. This includes content that lives in both the main repository and in other repositories in the Matplotlib organization.
The Narrative Documentation Leader is responsible for shepherding all of this content including the scope, organization, level, tone, and voice.
Responsible for ensuring that there is an agenda for the weekly meeting at it is followed.
Responsible for maintaining the weekly notes.
The true strength of Matplotlib and why it has had such longevity as a project is the community of people around the code. That community needs to be maintained. The Community Manager (CM) is a catch-all position for several very diverse tasks and this role may be split in the future and may want to enlist further assistants. The CM is responsible for Matplotlib’s evangelism, outreach, and user support as well as mainitaining the venues for conversation with the community.
