AtomicOrUnionType

Atomic types are organized in a tree hierarchy.

JSONiq defines the following build-in types that have a direct relation with JSON:

JSONiq also supports further atomic types, which were borrowed from XML Schema.

These datatypes are already used as a set of atomic datatypes by the other two semi-structured data formats of the Web: XML and RDF, as well as by the corresponding query languages: XQuery and SPARQL, so it is natural for a complete JSON data model to reuse them.
