Requirements

Please install the following programs:

• Trang

If you are on Ubuntu/Debian you can install these via:

sudo apt-get install trang

Also, note that your pip version should be >= 25.1.0.

Updating and pushing to Git and PyPI

1. Setup a virtual environment and install dependencies by running pip install --group dev --group test.
2. Run ./update.sh to update schema and regenerate models.
3. Review the generated commits and either open a PR with the changes or push them to master.
4. Create a new GitHub release using the correct tag format. Tags should follow the pattern 2.{MMD_SCHEMA_VERSION}.{PATCH}, where PATCH is incremented by 1 from the previous patch version. When the MMD_SCHEMA_VERSION is updated, the PATCH number should be reset to 0.
