A static documentation site for the OSCAL (Open Security Controls Assessment Language) data models, generated directly from the official NIST OSCAL Metaschema sources.

• Fetches the OSCAL Metaschema XML for every released OSCAL version at build time.
• Parses assemblies, fields, flags, and constraints, including inline define-assembly/define-field definitions.
• Renders a browsable reference for each model (catalog, profile, component-definition, SSP, AP, AR, POA&M) in both JSON and XML form.
• Provides a collapsible top-level format outline plus per-definition cards with linked properties, attributes, constraints, and remarks.

• Astro v6 (static SSG, output: 'static')
• fast-xml-parser with a custom DOCTYPE entity resolver
• Modular CSS under src/styles/ (tokens, base, layout, sidebar, cards, definitions, outline)
• Deployed via GitHub Actions (withastro/action) to GitHub Pages

Requires Node.js ≥ 22.12.

npm install
npm run dev      # http://localhost:4321/OSCAL-Info/
npm run build    # static output in ./dist
npm run preview

The build fetches metaschema sources from GitHub, so an internet connection is required.

Pushes to main trigger the GitHub Actions workflow in .github/workflows/, which builds the site and publishes dist/ to GitHub Pages.
