# asdf-coordinates-schemas — ASDF schemas for coordinates

License: unclear · Maintenance: active · Downloads: 216.0K/mo

## What it is and what it does

asdf-coordinates-schemas is a schema registry package for the ASDF (Advanced Scientific Data Format) ecosystem, providing validation rules for coordinate-related data tags. It is not designed for direct installation by end users; instead, it serves as a dependency for higher-level astronomy packages like asdf-astropy that need to validate and serialize coordinate data.

The package depends on asdf and asdf-standard, and its schemas are automatically registered when those packages load it. It supports current Python versions (3.10+) and is actively maintained. Most developers will encounter it indirectly through astronomy packages rather than installing it explicitly.

Use it for:

- Validating coordinate data serialized in ASDF format within astronomy pipelines
- Ensuring coordinate tag compliance when building asdf-astropy or similar astronomy packages
- Extending ASDF schema support for coordinate-heavy scientific data workflows

## Worth the install?

AI-flagged interpretation of the facts above — verify before relying.

Provides ASDF schemas for validating coordinate data structures, designed as a dependency for higher-level astronomy packages rather than direct end-user installation.

No, unless you are developing an ASDF-based astronomy package or explicitly need coordinate schema validation. The package is designed as a transitive dependency and the description explicitly recommends installing implementation packages like asdf-astropy instead. Direct installation is unnecessary for end users.

## Install

pip install asdf-coordinates-schemas
uv add asdf-coordinates-schemas
poetry add asdf-coordinates-schemas

## Installing asdf-coordinates-schemas

Before you install: Low install friction with a pure-Python wheel. Actively maintained with recent commits and stable production status, though typically installed transitively through packages like asdf-astropy rather than directly.

Quickstart:

# Typically installed as a transitive dependency
# Direct use is uncommon; schemas are loaded by asdf and asdf-standard
import asdf
# Coordinate schemas are registered automatically when asdf-coordinates-schemas is present

Requires Python >= 3.10; intended for use within asdf-based workflows, not standalone

Verify before relying:

- Whether the package's license is truly unspecified or if it inherits from asdf or asdf-standard
- Whether direct installation is ever necessary outside of development workflows
