            "exampleOfWork": {
                "@id": "packed.cwl#main/dir_array"
            },
            "name": "dir_array",
            "value": [
                {
                    "@id": "cb43436e1eb9f91dd954daff992dc6b852ddc3ee/"
                },
                {
                    "@id": "3c079cbf09e3c7181680f7be7d676acb3ec3403d/"
                }
            ]
        },
        {
