Version extension for PySTAC
Decision gist · record as of 2026-08-14
Yes, if you're building or maintaining a PySTAC catalog that needs to track dataset versions or deprecation status. The package is actively maintained, has no security issues, installs with minimal friction, and is permissively licensed. Install it only if you actually need version tracking; it's a specialized extension, not a general-purpose tool.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.10 or later; pystac-core must be installed as a runtime dependency.
- Low friction install with a single runtime dependency on pystac-core.
- Active maintenance with a recent release (4 days old) and no known vulnerabilities.

What it is and what it does
pystac-ext-version is a PySTAC extension package that implements the STAC Versioning Indicators Extension specification (v1.2.0). It provides a structured way to add version metadata to STAC items and collections, allowing you to track version numbers, deprecation status, and relationships between different versions of the same dataset or resource.
The package works as a plugin to pystac-core, adding schema validation and helper methods for working with version fields. It's designed for geospatial and imagery catalogs where datasets evolve over time and you need to maintain clear lineage between versions. The package version itself tracks the extension specification version it targets, with post-releases used for code updates that don't change the underlying extension version.
Use it for
- Track version history of satellite imagery or raster datasets in a STAC catalog
- Mark deprecated STAC collections and provide links to their replacement versions
- Maintain predecessor/successor relationships for evolving geospatial datasets
- Validate version metadata fields in STAC items using the v1.2.0 extension schema
