colcon-metadata
Extension for colcon to read package metadata from files.
Decision gist · record as of 2026-08-14
Yes, if you are actively using colcon and need to manage package metadata from a centralized repository. No, if you are not already using colcon or if you need active maintenance and support—the package has been dormant since 2020 and may not be compatible with recent colcon-core versions without verification.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires colcon-core to be installed and a colcon-compatible build environment; this is a plugin, not a standalone library.
- Low install friction with a pure-Python wheel.
- Maintenance is dormant: the latest release was 2020-08-10, over five years ago, though the repository remains active.

What it is and what it does
colcon-metadata is a plugin for the colcon build system that extends colcon-core to read and manage package metadata stored in remote repositories. It allows build systems to fetch structured information about packages—such as build configuration, dependencies, or other metadata—from centralized metadata repositories rather than deriving it solely from package source code.
The package is designed for teams using colcon as their build orchestration tool who need to maintain and distribute metadata separately from source repositories. It depends on colcon-core for the plugin framework and PyYAML for parsing metadata files. Development status is marked as Alpha, and the project has been dormant since August 2020, meaning it receives no active maintenance or updates.
Use it for
- Centralize package metadata for large colcon-based monorepos to avoid duplicating build configuration across many repositories.
- Fetch build metadata from a shared repository during CI/CD pipelines to configure builds without modifying source code.
- Manage cross-project dependencies and metadata in organizations using colcon as their primary build system.
