Clarify role of the Derived From field

[white-gecko]

The "Derived From" field in the input form of the Publish Wizard is a multi line filed without any specific validation.

This caused the impression for me that it should hold an unstructured description of the provenance of the dataset. However in the generated JSON data it is represented as in one field wasDerivedFrom which is then converted to one IRI <https://metadata.coypu.org/dataset/wikidata-distribution https://query.wikidata.org/> which is not accepted by gstore.

[
  {
    "@type": [
      "Version",
      "Dataset"
    ],
    "@id": "https://databus.coypu.org/narndt/coypu/countries/2023-09-18T122214Z",
    "hasVersion": "2023-09-18T122214Z",
    "title": "Countries",
    "abstract": "Countries 2023-09-18T12:22:14Z",
    "description": "Countries 2023-09-18T12:22:14Z",
    "license": "https://dalicc.net/licenselibrary/Cc010Universal",
    "attribution": null,
    "wasDerivedFrom": "https://metadata.coypu.org/dataset/wikidata-distribution\nhttps://query.wikidata.org/",
    "distribution": [
      {
        "@type": "Part",
        "formatExtension": "ttl",
        "compression": "none",
        "downloadURL": "https://databus.coypu.org/dav/narndt/coypu/countries/2023-09-18T122214Z/countries_freqency=static.ttl",
        "dcv:frequency": "static"
      }
    ]
  }
]

My expectations

The input form should get some kind of description which data shall be inserted in this filed and the data should be validated by the databus before it is sent to the store.

I see two problems here:

• the interface allows to enter something except IRI
• the API passes through the wrong input (the context specifies that it must be @id, but there is no check the the actual data is an id)

I will change the interface and add a server-side check before saving to gstore. I will try to also allow adding multiple derivedFrom triples via the UI
