0001 Use Backstage to Support Maintainers#
OEP-55 laid out that we should document the maintainers of a component.
As a maintainer it is hard to know what components you are maintaining.
As a community member it is currently difficult to quickly look up who the maintainers are for multiple components quickly.
Given the number of repos that make up the Open edX platform and the complexity of the job of maintaining them, we need a system for cataloging, and making transparent the critical details of our repositories.
To solve the above issues and to enable the potential to ease other discoverability and maintainership burdens, the Open edX community shall maintain a backstage instance and related metadata.
To support the backstage instance ownership data will have to be stored in a structured way. We will follow Backstage best practices and store this data in a
catalog-info.yamlfile in each component repository.
Once a backstage instance exists we have the opportunity to further leverage it as a centralized access point for maintainers as well as community members to quickly and easily assess different components and find relevant links to code, documentation, owners, etc.
Backstage will also give us the ability to expose other health metrics to maintainers so they can more easily assess the components they own.
As a result of adding the
catalog-info.yamlfile we end with two top-level files that have very similar data. If this decision is not reversed after the initial pilot, it may make sense to revisit this consequence and see if we can consolidate this metadata into a single file. tcril-engineering#331 has been created to follow up on this work.
Easy to build and get a high level view of the system.
Not a beautiful UI for maintainers to work with.
Data overload as we put more and more data into it with little to no control over the presentation of the data.
Owners in the Readme#
Easy to see while in the repo.
Harder to aggregate the data from the unstructured files in a way that would allow us to easily build a single pane of glass where maintainers can see all the things they own.

Backstage system model has detail about the different kinds of components and how they connect to each other.
catalog-info.yamlfile. Comments here starting with “Required” or “Optional” shouldn’t appear in the file, they are here to help explain the sample:
