estabishmentMeans facet labels in API are JSON objects instead of strings

[nielsklazenga]

This is what the facet result for establishmentMeans looks like now:

{
  "facetResults": [
    {
      "fieldName": "establishment_means",
      "fieldResult": [
        {
          "label": "{\"concept\": \"Introduced\", \"lineage\": [\"Introduced\"]}",
          "i18nCode": "establishment_means.{\"concept\": \"Introduced\", \"lineage\": [\"Introduced\"]}",
          "count": 814485,
          "fq": "establishment_means:\"{\\\"concept\\\": \\\"Introduced\\\", \\\"lineage\\\": [\\\"Introduced\\\"]}\""
        },
        {
          "label": "{\"concept\": \"Native\", \"lineage\": [\"Native\"]}",
          "i18nCode": "establishment_means.{\"concept\": \"Native\", \"lineage\": [\"Native\"]}",
          "count": 82270,
          "fq": "establishment_means:\"{\\\"concept\\\": \\\"Native\\\", \\\"lineage\\\": [\\\"Native\\\"]}\""
        },
        {
          "label": "{\"concept\": \"Uncertain\", \"lineage\": [\"Uncertain\"]}",
          "i18nCode": "establishment_means.{\"concept\": \"Uncertain\", \"lineage\": [\"Uncertain\"]}",
          "count": 459,
          "fq": "establishment_means:\"{\\\"concept\\\": \\\"Uncertain\\\", \\\"lineage\\\": [\\\"Uncertain\\\"]}\""
        },
        {
          "label": "Not supplied",
          "i18nCode": "establishment_means.novalue",
          "count": 2855500,
          "fq": "-establishment_means:*"
        }
      ]
    }
  ],
}

Both in the label and the fq are JSON strings instead of the clean values.

The same happens in the download through the API:

It was not possible to download establishment means before, so this is progress, but having the JSON there instead of the value makes that you cannot, for example, use the PostgreSQL COPY to load the records, but have to load the records one by one, which will be prohibitive for larger downloads (my downloads for the maps in our flora are around 3.7 million records). Downloads through the UI do not seem to have this problem.

Valued of processed->occurrence->establishmentMeans is an json: 'establishmentMeans: "{"concept": "vagrant", "lineage": ["vagrant"]}"'

Our current EstablishmentMean model has two fields: concept and lineage, but EstablishmentMean in the latest DWC core is defined as a controlled value string

It has the same issue on our Biocache prod
