## What it is
CKAN is an open-source data management system (DMS) for powering data hubs and open data portals, providing dataset cataloging, storage, rich search, a full API, and visualization tools. It is a mature, extensible Python web application used by governments and enterprises worldwide, including catalog.data.gov and data.humdata.org.

## Use cases
- publish and catalog open datasets for a government data portal
- run a self-hosted data hub with a searchable dataset catalog
- expose structured data via a REST API for a data catalog
- build a federated network of data portals sharing datasets
- add metadata management and dataset previews to an organization's data assets
- visualize cataloged data as charts and geospatial views

## When to choose
- you need a mature, battle-tested open data portal with a large extension ecosystem
- you want cataloging, search, datastore, API, and visualization out of the box
- you are a government or enterprise publishing large numbers of public datasets
- you need theming and plugin (ckanext) extensibility

## When to avoid
- you only need a lightweight dataset file store without cataloging or metadata workflows
- you want a general-purpose relational database rather than a cataloging platform
- you need a real-time streaming or ETL pipeline tool rather than a data portal

## Facets
