# amundsen-common — Common code library for Amundsen

License: unclear · Maintenance: active · Downloads: 77.4K/mo

## What it is and what it does

Amundsen Common is a shared library for the Amundsen data discovery platform, designed to hold code reused across Amundsen's microservices. It provides common data models and utilities built on Flask, attrs, and marshmallow to standardize how services communicate and validate data. The library requires Python >= 3.8 and is part of the larger Amundsen ecosystem.

This package is primarily useful if you are building or extending Amundsen services or integrating with the Amundsen platform. It is not a standalone tool but rather an internal dependency that handles shared patterns between Amundsen components. If you are running Amundsen, you will likely pull this in transitively through other Amundsen packages rather than installing it directly.

Use it for:

- Building a custom Amundsen microservice that needs to share data models and validation logic with other services.
- Extending Amundsen's core services with additional metadata connectors or search features.
- Integrating with an existing Amundsen deployment to add custom business logic or domain-specific metadata handling.
- Contributing to the Amundsen project itself and needing the common utilities for local development.

## Worth the install?

AI-flagged interpretation of the facts above — verify before relying.

Amundsen Common provides shared utilities and data models for Amundsen's microservices, handling common serialization and validation patterns across the platform.

Yes, if you are working with or extending Amundsen. No, if you are not already using Amundsen—this is an internal library for the Amundsen ecosystem and has no standalone utility. Install it as a transitive dependency through other Amundsen packages, or directly if you are building a custom Amundsen service. The unclear license status warrants verification before use in proprietary contexts.

## Install

pip install amundsen-common
uv add amundsen-common
poetry add amundsen-common

## Installing amundsen-common

Before you install: Low install friction with four lightweight runtime dependencies. Actively maintained with last commit on 2026-08-01 and no recent security vulnerabilities reported.

License in practice: License treatment is unclear—no SPDX identifier or raw license text is available in the package metadata. Verify the actual license before use in proprietary or restricted contexts.

Quickstart:

pip install amundsen-common==0.32.0

from amundsen_common import some_module
# Use shared utilities from amundsen-common in your Amundsen service

Requires Python >= 3.8

Verify before relying:

- What is the actual license under which amundsen-common is distributed?
- Are there any breaking changes between 0.32.0 and earlier versions that affect dependent services?
