Usage

As a Git Submodule

# In your project:
git submodule add https://github.com/ASCS-eV/asam-openx-standards.git submodules/asam-openx-standards

For AI/LLM Context

The markdown files are optimized for AI agent consumption:

• Each file has a metadata header (source URL, version, license, download date)
• Chapter-level granularity enables precise citation
• INDEX.md in each standard directory provides navigation

Citation Convention

When referencing in code or schemas:

# [OpenDRIVE] §7.3 — Lane borders
# [OpenODD] Annex B — ISO 34503 taxonomy
# [OpenSCENARIO] §5.2.1 — Entity types

Refreshing Standards

python scripts/download_asam_specs.py --all --no-verify

Use --standard <name> for individual updates. See --help for options.
