CWL 2 OCI¶

cwl2oci is a Transpiler-Mate API plugin that converts normalized CWL software metadata and one selected CWL process into an OCI image annotation map.

It writes an annotations.json file shaped like this:

{
  "$manifest": {
    "org.opencontainers.image.title": "Hello workflow",
    "org.opencontainers.image.version": "1.0.0",
    "org.cwl.entrypoint": "main",
    "org.cwl.type": "Workflow"
  }
}

The plugin generates metadata only. It does not build or publish an OCI image, and it does not provide a standalone CLI.

Choose your path¶

• Generate your first annotation file in a guided Python tutorial.
• Install and configure the plugin for a specific task.
• Look up the exact plugin contract or annotation mapping.
• Understand the architecture and data flow.

Requirements¶

• Python 3.10 or newer
• A Transpiler-Mate-compatible host when the plugin is not invoked directly
• A context containing normalized software metadata and a selected CWL process
