# autosar-data — read, write and modify Autosar arxml data using Python

License: unclear · Maintenance: active · Downloads: 113.8K/mo

## What it is and what it does

autosar-data is a Python wrapper around a Rust library for working with AUTOSAR arxml files. It lets you load, validate, create, and modify AUTOSAR data models programmatically. The package supports strict and non-strict validation modes, cross-references, AUTOSAR paths, and multiple file handling within a single model. It covers AUTOSAR versions 4.0.1 and later.

The bindings expose core operations: file I/O (load from file or buffer, serialize, write), element creation and navigation, attribute and reference management, and bulk traversal via depth-first search. No runtime dependencies are required beyond Python 3.11+, making it lightweight to integrate into automotive tooling, configuration management, or data transformation pipelines.

Use it for:

- Parse and validate AUTOSAR configuration files in automotive ECU development workflows
- Programmatically generate or modify arxml files for system architecture or signal definition
- Extract and analyze AUTOSAR model data (PDUs, signals, packages) for reporting or compliance checks
- Migrate or transform AUTOSAR data between versions or file structures
- Integrate AUTOSAR data processing into Python-based build or CI/CD automation

## Worth the install?

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

Python bindings for reading, writing, and modifying AUTOSAR arxml files with full validation support and cross-reference handling.

Yes, if you work with AUTOSAR arxml files and need programmatic access from Python. Active maintenance, no known vulnerabilities, and prebuilt wheels across major platforms reduce friction. Verify the license terms first—the unclear license status is the only material blocker. Requires Python 3.11+.

## Install

pip install autosar-data
uv add autosar-data
poetry add autosar-data

## Installing autosar-data

Before you install: Medium install friction due to compiled wheels; prebuilt binaries available for Python 3.11+ across macOS, Windows, and Linux architectures. Active maintenance with recent release (54 days ago).

License in practice: License status unclear—no SPDX identifier or raw license text provided. Verify licensing terms before use in proprietary or commercial projects.

Quickstart:

from autosar_data import *

model = AutosarModel()
(arxmlfile, warnings) = model.load_file("filename.arxml", False)

# Access elements by path
element = model.get_element_by_path("/Pkg/System")

Requires Python 3.11 or later; compiled Rust extension via PyO3.

Verify before relying:

- Exact license terms and compatibility with GPL, proprietary, or commercial use
- Performance characteristics when handling large arxml files
- Degree of AUTOSAR 4.0.1+ version coverage and backward compatibility
