[burgerga]

See https://github.com/citation-file-format/citation-file-format/blob/main/schema-guide.md#definitionspersonname-particle

authors:
  - family-names: Humboldt
    given-names: Alexander
    name-particle: von

will result in

[[1]]
[[1]]$type
[1] "Person"

[[1]]$name
[1] "Alexander Humboldt"

[[1]]$givenName
[1] "Alexander"

[[1]]$familyName
[1] "Humboldt"

instead of "Alexander von Humboldt".

Particularly problematic when working with Dutch names ;)
