What is Token-Oriented Object Notation (TOON)?

TOON is a conceptual data representation model where structured data is encoded as machine-interpretable tokens instead of hierarchical objects.

Is TOON an official data format?

No. TOON is currently a conceptual idea rather than an established industry standard like JSON or XML.

Token-based structures may improve machine processing efficiency by making semantic meaning explicit and reducing complex hierarchical parsing.

Yes. Technologies such as Protocol Buffers, Apache Avro, MessagePack, and CBOR already provide machine-optimized serialization formats.

JSON will likely remain dominant for APIs, but specialized systems may adopt alternative formats optimized for performance and machine processing.
