Every property here holds an array, and a property this definition does not name is still checked: it must be an array too. Naming a property buys a check on what its values look like, and nothing else.

The schema

https://blue-core-lod.github.io/bibframe-json/schema/dialect/Item.json is this definition on its own, and https://blue-core-lod.github.io/bibframe-json/schema/dialect.json is the whole shape with every definition inlined. They are checked against each other over the conformance corpus, so either is safe to depend on.
