Content Delivery Network Interconnection (CDNI) Media Type Registration

Abstract

   This document defines the standard media type used by the Content

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.
