Adds a dataset-version schema example for the datacite-based "national gallery dataset"

[jsheunis]

With this example data, a datacite metadata record is converted to be compliant with the dataset-version schema. The dataset described by the datacite record is known as the 'External Environmental Data' dataset from the British National Gallery. See https://api.test.datacite.org/dois/10.82433/9184-DY35\?publisher\=true\&affiliation\=true.

Mappings that were not straightforward:

• The datacite record had no intuitive choice for the name property of a DatasetVersionObject
• keywords were taken from record["data"]["attributes"]["subjects"]
• the record has a DOI with value 10.82433/9184-dy35; however, https://doi.org/10.82433/9184-dy35 does not resolve. It still seems to be the only viable identifier in the record though (e.g. record["data"]["attributes"]["identifiers"] = [])
• modified was taken from the date part of record["data"]["attributes"]["updated"] which has value "2024-01-02T20:15:20.000Z"
• landing_page was taken from the most relevant source in the record["data"]["attributes"]["relatedIdentifiers"] list
• The record has a couple of relations aren't exact matches for available ones in the citation ontology:
  • used cito:supports for isSupplementTo
  • used cito:isSupportedBy for IsSupplementedBy
• Had a challenge figuring out what metatype would be ascribed to an entity that has a resource type of InteractiveResource in the datacite record, and is identified by a URL. Organizations/Persons and Publications were easy, in this case the relation is to an online page, essentially. This part of the data example (the entity and the relation) is commented out.

Some issues were encountered when trying to validate the example locally. However, when I ran validation on the penguin dataset locally, i received the same errors. And these errors do not show up on the CI, so perhaps this issue is related to my run environment...

Oh, I guess the issues are there because I didn't apply the patches locally...

Thank you!
