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 (transpiler-mate plugin)
Install the runtime and plugin in the same Python environment:
pip install transpiler-mate-runtime "cwl2ogc>=0.20.0"
Generate OGC input/output descriptions from your CWL document:
transpiler-mate cwl2ogc --output processes.json workflow.cwl
Show command help:
transpiler-mate cwl2ogc --help
The output contains application metadata and a processes mapping keyed by
CWL process ID. See the plugin guide for source requirements
and output details.
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()
