RFC 9404: JSON Meta Application Protocol (JMAP) Blob Management Extension
In plain English — editorial summary, not part of the RFC
The JSON Meta Application Protocol (JMAP) base protocol (RFC 8620) provides the ability to upload and download arbitrary binary data via HTTP POST and GET on a defined endpoint. This binary data is called a "blob". This extension adds additional ways to create and access blobs by making inline method calls within a standard JMAP request. This extension also adds a reverse lookup mechanism to discover where blobs are referenced within other data types.
