[gdal-dev] How far can we resolve complex GeoJSON?

[Rahkonen Jukka (MML)]

Hi,

Have a look at data returned by request https://beta-paikkatieto.maanmittauslaitos.fi/geographic-names/wfs3/v1/collections/placenames/items?municipality=837&limit=100
There exists couple of features with "parallelName" and GDAL converts that part into a string type attribute

  parallelName (String) = [ { "placeNameId": 40581553, "placeNameVersionId": 2, "spelling": "Pirkkahalli", "language": "fin", "languageOfficiality": 1, "languageDominance": 1, "placeNameSource": 1, "placeNameStatus": 5, "placeNameCreationTime": "2008-12-05T22:00:00Z", "placeNameModificationTime": "2017-02-15T10:41:10Z", "placeNameDeletionTime": null } ]

Can we do anything else with GDAL and GeoJSON driver? I suppose it does not same kind of advanced features like GMLAS driver has.
Here is one placename as an example. A place can have zero to n parallel names.

{
      "type": "Feature",
      "id": "PN_40581553",
      "properties": {
