ASDF WCS schemas
Decision gist · record as of 2026-08-14
Yes, if you are building or using a WCS library that depends on it. No, if you are an end user—install an implementation package instead. The package is actively maintained, has low install friction, and carries no known vulnerabilities. The only caveat is that the license treatment is unclear, so verify licensing terms from the repository before use in proprietary or copyleft-sensitive projects.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python >=3.9
- Low install friction with a pure Python wheel.
- The package is actively maintained with a recent commit on 2026-07-20 and has been in production-stable status since its first release in 2021-11-24.

What it is and what it does
asdf-wcs-schemas is a schema-definition package that supplies ASDF schemas for validating World Coordinate System metadata and tags. It is part of the ASDF ecosystem and is designed to be installed as a transitive dependency of higher-level WCS libraries rather than used directly by end users.
The package depends on asdf-standard, asdf-transform-schemas, and asdf-coordinates-schemas to provide a complete schema validation framework. It requires Python >=3.9 and is classified as production-stable. With no known vulnerabilities and active maintenance, it serves as a foundational schema layer for WCS data serialization and validation in scientific workflows.
Use it for
- Enable WCS libraries to correctly parse and validate WCS tags in ASDF files
- Support scientific data pipelines that require standards-compliant WCS schema enforcement
- Extend ASDF schema validation to include world coordinate system definitions
- Provide schema infrastructure for ASDF-based astronomical data serialization

Before you install
Low install friction with a pure Python wheel. The package is actively maintained with a recent commit on 2026-07-20 and has been in production-stable status since its first release in 2021-11-24. It depends on three ASDF-related packages (asdf-standard, asdf-transform-schemas, asdf-coordinates-schemas), which are standard infrastructure dependencies.
Requires Python >=3.9
License in practice

dill extends Python's pickle module to serialize and deserialize a much wider range of Python objects, including functions, lambdas, classes, and interpreter sessions, to byte streams for storage or network transmission.
Multiprocess is an enhanced fork of Python's standard multiprocessing library that uses dill for better serialization, allowing you to spawn processes with a threading-like API and share complex objects between them.
Install it if you use multiprocessing and encounter pickle serialization limits with lambdas or complex objects.
