cwl2ogc

cwl2ogc converts CWL workflow/tool inputs and outputs into:

• OGC API - Processes I/O descriptors
• JSON Schema documents for those I/O definitions

This is useful when publishing CWL-based application packages through OGC API - Processes interfaces.

Why

The OGC API - Processes Deploy/Replace/Undeploy workflow requires a process description that exposes valid input and output metadata. cwl2ogc helps generate that description directly from CWL definitions.

Installation

pip install cwl2ogc

Python 3.10+ is required.

Quick Start (CLI)

Generate a process descriptor from a CWL document:

cwl2ogc tests/artifacts/cwl-types/inp.cwl \
  --workflow-id inp \
  --output process.json

Show command help:

cwl2ogc --help

Quick Start (Python API)

from cwl_utils.parser import load_document_by_uri
from cwl2ogc import BaseCWLtypes2OGCConverter

workflow = load_document_by_uri("tests/artifacts/cwl-types/inp.cwl#inp")
converter = BaseCWLtypes2OGCConverter(workflow)

inputs = converter.get_inputs()
outputs = converter.get_outputs()

inputs_json_schema = converter.get_inputs_json_schema()
outputs_json_schema = converter.get_outputs_json_schema()

Playground

Requirements:

• docker
• task

Run the published playground image:

task run-playground

Build and run the local playground image:

task run-playground-dev

Open http://127.0.0.1.

Development
