## What it is
Apache Atlas is an open-source metadata management and data governance framework providing a shared metadata store, data lineage, and classification for the Hadoop ecosystem and beyond. It integrates with Apache Ranger for policy-based access control and offers REST APIs plus a web UI for searching and governing enterprise metadata.

## Use cases
- build a data catalog for our enterprise data lake
- track table and column lineage across Hadoop jobs
- classify sensitive data for compliance and governance
- integrate metadata with Apache Ranger for access control
- search and discover datasets across the data ecosystem
- manage business taxonomy and glossary terms for data assets

## When to choose
- you run Hadoop or big-data infrastructure and need centralized metadata governance
- you need automated data lineage and classification across many data systems
- you want metadata-driven security policies via Ranger integration

## When to avoid
- you need a lightweight catalog for a small cloud-native stack without Hadoop
- you cannot operate a JVM-based service with its own graph database and dependencies
- you only need simple schema documentation rather than full governance

## Facets
- artifact type: application
- maturity: active
- function: search-engine, api-framework, monitoring, security
- domain: big-data, databases, analytics, security
- platform: jvm, python, self-hosted
