The JMAP base protocol (RFC8620) provides the ability to upload and download arbitrary binary data via HTTP PUT and GET on 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 datatypes.
