1. Introduction and Scope
The Content Delivery Network Interconnection (CDNI) working group is
developing a set of protocols to enable the interconnection of
multiple content delivery networks (CDNs), as discussed in [RFC6770].
The CDNI protocol suite consists of multiple HTTP-based interfaces,
many of which transfer various payloads encoded in JSON (JavaScript
Object Notation) [RFC7159]. The main interfaces (i.e., CDNI Control
interface, CDNI Footprint & Capabilities Advertisement interface,
CDNI Request Routing Redirection interface, CDNI Metadata interface,
and CDNI Logging interface) are described in [RFC7336]. It is
desirable to be able to indicate the type of object carried in the
HTTP entity-body without having to register separate media types for
each CDNI object. To accomplish this aim, this document defines a
single new media type for CDNI that includes a required payload-type
parameter. A separate registry of CDNI payload-type parameters is
also defined. CDNI protocol specifications may register interface-
specific payload types, specifying the payload encoding and parsing
semantics for that message (e.g., JSON serialization for a CDNI
metadata object). The same payload-type parameter may also be used
as references for other purposes (e.g., referencing CDNI metadata
objects from CDNI capability advertisement objects).

2. IANA Considerations
This section contains the CDNI media type registration as well as the
payload-type parameter registry definition for IANA.
2.1. CDNI Media Type
Type name: application
Subtype name: cdni
Required parameters:
ptype
The required parameter "ptype" describes the type of CDNI
message contained in the message payload, as registered in the
"Content Delivery Network Interconnection (CDNI) Parameters"
registry (Section 2.2) defined below.
Optional parameters: none
Encoding considerations:
