Conversion creates empty fields when adding new metadata keys

[jh-RLI]

Should it be possible to add some user input to new fields like "is_about" or should omi just convert the metadata and leave the editing to tools like the MetaEditor on the OEP.

Example:

{
    "name": "id",
    "description": "Unique identifier",
    "type": "serial",
    "is_about": [
        {
            "name": "",
            "path": ""
        }
    ],
    "value_reference": [
        {
            "value": "",
            "name": "",
            "path": ""
        }
    ]
}
