Open Job Description (OpenJD) is a flexible open specification for defining render jobs which are portable between studios and render solutions. This package provides a command-line interface that can be used to validate OpenJD templates, run OpenJD jobs locally, and more.
For more information about Open Job Description and our goals with it, please see the Open Job Description Wiki on GitHub.
This library requires:
- Python 3.9 or higher;
- Linux, MacOS, or Windows operating system;
- On Linux/MacOS:
sudo
This package's version follows Semantic Versioning 2.0, but is still considered to be in its initial development, thus backwards incompatible versions are denoted by minor version bumps. To help illustrate how versions will increment during this initial development stage, they are described below:
- The MAJOR version is currently 0, indicating initial development.
- The MINOR version is currently incremented when backwards incompatible changes are introduced to the public API.
- The PATCH version is currently incremented when bug fixes or backwards compatible changes are introduced to the public API.
We encourage all contributions to this package. Whether it's a bug report, new feature, correction, or additional documentation, we greatly value feedback and contributions from our community.
Please see CONTRIBUTING.md for our contributing guidelines.
