asdf-wcs-schemas

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

Worth the install?

AI-flagged interpretation of the facts on this page — verify before relying

Provides ASDF schemas for validating World Coordinate System (WCS) tags in ASDF files. This is a schema package intended as a dependency for WCS implementation libraries rather than direct end-user installation.

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.

Install

asdf-wcs-schemas on PyPI

pip install asdf-wcs-schemas

uv add asdf-wcs-schemas

poetry add asdf-wcs-schemas

Installing asdf-wcs-schemas

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.

License in practice

License treatment is unclear—no SPDX identifier or raw license text is available in the metadata. Before relying on this package in a commercial or copyleft-sensitive context, verify the actual license from the repository.

Quickstart

# Install as a dependency of a WCS implementation package
pip install asdf-wcs-schemas

# Typically used indirectly through asdf-standard, asdf-transform-schemas, asdf-coordinates-schemas
import asdf

Requires Python >=3.9

Verify before relying

• Actual license terms and conditions (metadata shows 'unclear' treatment with no SPDX or raw license data)
• Whether direct installation is ever necessary outside of transitive dependency chains
