Hi Alexey, 

This is the first of two requests from a Linux Foundation project (the ADs confirmed that these could be submitted as standards-tree requests). Would you be able to review these by May 18th?

thanks,
Amanda

Media type name: application

Media subtype name: vnd.cloudevents-batch+json

Required parameters: N/A

Optional parameters: N/A

Encoding considerations: binary

as per application/json

Security considerations: The CloudEvents specification and format does not directly deal with security with respect to on-the-wire protections. Since the CloudEvents format is really about standardizing how data appear within a message, not what the data is, it is assumed that existing transport security mechanisms will be used. In this respect, CloudEvents is meant to be additive to existing transport flows.

Specifically, to the points mentioned in the instructions:
- A CloudEvent is not meant to contain active or executable content - at least not as part of the CloudEvents definition itself. It's just text/binary data to CloudEvents.
- CloudEvents itself doesn't need privacy or integrity services. If needed by the application, they can layer that on top of the CloudEvent structure, but it is out of scope for CloudEvents.

Interoperability considerations: As this is a usage/variant of application/json, this media type does not introduce any new interoperability concerns.
