Python-Based EXI Encoding and Decoding with CH4ESE

A streamlined Python solution for EXI format conversion.
Technology No. CW-24-42

The Challenge:

For software developers and testers, particularly those working with electric vehicle infrastructure, the lack of a Python-based tool for EXI (Efficient XML Interchange) encoding and decoding has been a bottleneck. The primary open-source solution for EXI conversion is written exclusively in Java, requiring teams to manage multiple environments, which adds complexity and reduces workflow efficiency. This reliance on Java also limits integration flexibility for those whose projects are predominantly Python-based, creating a need for a robust, Python alternative.


How It Works:

CH4ESE is a Python3-based tool for EXI encoding and decoding, fully compatible with the W3C EXI format standard. Built on EXIficient, an open-source EXI library, CH4ESE translates XML to EXI and vice versa directly from Python. Users can interact with CH4ESE via a command-line interface for batch processing or utilize its web server mode for on-demand, live translation. This functionality streamlines setup and integration within Python projects, particularly beneficial for teams committed to a Python-only ecosystem.


Key Advantages:

- Written in Python: CH4ESE is coded entirely in Python, removing the need to run Java-based tools, simplifying the environment setup.

- Flexible Translation Modes: Supports command-line translation for batch processing and a web server mode for real-time EXI conversions.

- Community-Driven Development: Built by Python developers for Python developers, CH4ESE is positioned to grow with contributions from a targeted community dedicated to Python-exclusive solutions.


Market Applications:

- Electric Vehicle Infrastructure: Developers and testers in EV systems can use CH4ESE for consistent, Python-based EXI translations, supporting seamless integration into Python-centric pipelines.

- Software Development: Ideal for teams working in Python who require a straightforward, command-line or live translation tool for EXI encoding and decoding without switching languages or environments.
