Array Inputs¶

Array Inputs refers to the 2.4.2. Array Inputs paragraph of the 2.4. Inputs chapter of the Common Workflow Language User Guide

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('https://raw.githubusercontent.com/eoap/cwl2ogc/refs/heads/develop/tests/artifacts/cwl-types/array-inputs.cwl')
from cwl2ogc import load_converter_from_location

cwl_coverter = load_converter_from_location('https://raw.githubusercontent.com/eoap/cwl2ogc/refs/heads/develop/tests/artifacts/cwl-types/array-inputs.cwl')

2. Inputs conversion¶

Once the document is parsed, invoke the cwl2ogc APIs to convert the CWL inputs to the OGC JSON format:

import sys

cwl_coverter.dump_inputs(stream=sys.stdout, pretty_print=True)
import sys

cwl_coverter.dump_inputs(stream=sys.stdout, pretty_print=True)

{
  "filesA": {
    "schema": {
      "type": "array",
      "items": {
        "type": "string"
      }
    },
    "metadata": [
      {
        "title": "cwl:type",
        "value": "string[]"
      }
    ],
    "minOccurs": 1,
    "maxOccurs": 1,
    "valuePassing": "byValue",
    "title": "filesA label",
    "description": "filesA doc"
  },
  "filesB": {
    "schema": {
      "type": "array",
      "items": {
        "type": "string"
      }
    },
    "metadata": [
      {
        "title": "cwl:type",
        "value": "string[]"
      }
    ],
    "minOccurs": 1,
    "maxOccurs": 1,
    "valuePassing": "byValue",
    "title": "filesB label",
    "description": "filesB doc"
  },
  "filesC": {
    "schema": {
      "type": "array",
      "items": {
        "type": "string"
      }
    },
    "metadata": [
      {
        "title": "cwl:type",
        "value": "string[]"
      }
    ],
    "minOccurs": 1,
    "maxOccurs": 1,
    "valuePassing": "byValue",
    "title": "filesC label",
    "description": "filesC doc"
  }
}

3. Outputs conversion¶

Users can reuse the BaseCWLtypes2OGCConverter instance to convert the CWL outputs to the OGC JSON format:

cwl_coverter.dump_outputs(stream=sys.stdout, pretty_print=True)
cwl_coverter.dump_outputs(stream=sys.stdout, pretty_print=True)

{
  "example_out": {
    "schema": {
      "type": "string"
    },
    "metadata": [
      {
        "title": "cwl:type",
        "value": "stdout"
      }
    ]
  }
}
