Imported CWL types¶
Follow below an example to demonstrate how the library handles and convert a CWL where inputs are imported from an external URL.
1. Parsing¶
In this sample we'll show the access from a remote public URL.

from cwl2ogc import load_converter_from_location
cwl_coverter = load_converter_from_location('../tests/artifacts/cwl-types/app.cwl')
from cwl2ogc import load_converter_from_location
cwl_coverter = load_converter_from_location('../tests/artifacts/cwl-types/app.cwl')
2. Inputs conversion¶
Once the document is parsed, invoke the cwl2ogc APIs to convert the CWL inputs to the OGC JSON format:

3. Outputs conversion¶
Users can reuse the BaseCWLtypes2OGCConverter instance to convert the CWL outputs to the OGC JSON format:
