Encoding considerations: binary

This is a JSON document, and the encoding considerations are the same as for media type application/json defined in IETF RFC 8259 [25].

Security considerations: This media format is a JSON document and inherits the security considerations provided in IETF RFC 8259 [25].
The format does not incorporate any active or executable content. However, other forms of material from outside resources can be referenced by the format, and this material can contain active or executable content. Such material is expected to be identified by its own MIME type, and the security considerations of that format should be taken into account.
This format is highly susceptible to manipulation or spoofing for attacks designed to inject fake information. Both integrity protection and source authentication are recommended to prevent misleading of the recipient.
