draft-hansen-media-type-suffix-regs-00
Abstract
This document defines several Structured Syntax Suffixes for use with
media type registrations. In particular, it defines and registers
the "+json", "+der", "+fastinfoset" and "+wbxml" Structured Syntax
Suffixes.

1. Introduction
[RFC3023] created the +xml suffix convention that may be used by
media types whose representation uses XML underneath, that is, they
could have been successfully parsed as if the media type had been
application/xml in addition to their being parsed as their media type
that is using the +xml suffix. [I-D.ietf-appsawg-media-type-regs]
defines a registry to be used for future Structured Syntax Suffixes.
A variety of Structured Syntax Suffixes have already been used in
some Media Type registration, in particular "+json", "+der",
"+fastinfoset" and "+wbxml". This document defines and registers
these four Structured Syntax Suffixes in the Structured Syntax Suffix
registry.
Discussion of this document should occur in the Apps Area Working
Group (apps-discuss@ietf.org).
2. When to Use these Structured Syntax Suffixes
Each of the Structured Syntax Suffixes defined in this document are
appropriate for use when the media type identifies the semantics of
the protocol payload. That is, knowing the semantics of the specific
media type provides for more specific processing of the content than
that afforded by generic processing of the underlying representation.
At the same time, using the suffix provides receivers of the media
types to do generic processing of the underyling representation in
cases where they do not need to handle specially the specific
semantics of the exact media type.
3. The +json Structured Syntax Suffix
[RFC4627] defines the "application/json" media type. The suffix
"+json" may be used with any media type whose representation follows
that established for "application/json". The Structured Syntax
Suffix registration form follows:
Name JavaScript Object Notation (JSON)
+suffix +json
References [RFC4627]
Encoding considerations Per [RFC4627], JSON may be represented using
UTF-8, UTF-16, or UTF-32. When JSON is written
in UTF-8, JSON is 8bit compatible. When JSON is
written in UTF-16 or UTF-32, JSON is binary.

4. The +der Structured Syntax Suffix
The CCITT defined the Distinguished Encoding Rules (DER) message
transfer syntax in [CCITT.X690.2002]. The suffix "+der" may be used
with any media type whose representation follows the DER message
transfer syntax. The Structured Syntax Suffix registration form
follows:
Name Distinguished Encoding Rules (DER) message
transfer syntax
+suffix +der
References [CCITT.X690.2002]
Encoding considerations DER is a binary encoding.
Interoperability considerations n/a
Security considerations There are no security considerations inherent
in DER. Each individual media type registered
with a +der suffix may have additional security
considerations.

5. The +fastinfoset Structured Syntax Suffix
The ITU-T and ISO have defined the Fast Infoset document format as a
binary representation of the XML Information Set in [ITU.X891.2005]
and [ISO.IEC.24824-1.2007]. These documents further define the
"application/fastinfoset" media type. The suffix "+fastinfoset" may
be used with any media type whose representation follows that
established for "application/fastinfoset". The Structured Syntax
Suffix registration form follows:
Name Fast Infoset document format
+suffix +infoset
References [ITU.X891.2005] and [ISO.IEC.24824-1.2007]
Encoding considerations Fast Infoset is a binary encoding. The
binary, quoted-printable and base64 content-
transfer-encodings are suitable for use with Fast
Infoset.
Interoperability considerations n/a
Security considerations There are no security considerations inherent
in Fast Infoset. Each individual media type
registered with a +der suffix may have additional
security considerations.

6. The +wbxml Structured Syntax Suffix
Hansen Expires October 05, 2012 [Page 3]
Internet-Draft Additional Media Type Suffixes April 2012
The WAP Forum has defined the WAP Binary XML (WBXML) document format
as a binary representation of XML in [WBXML]. This document further
defines the "application/vnd.wap.wbxml" media type. The suffix
"+wbxml" may be used with any media type whose representation follows
that established for "application/vnd.wap.wbxml". The Structured
Syntax Suffix registration form follows:
Name WAP Binary XML (WBXML) document format
+suffix +wbxml
References [WBXML]
Encoding considerations WBXML is a binary encoding.
Interoperability considerations n/a
Security considerations There are no security considerations inherent
in WBXML. Each individual media type registered
with a +der suffix may have additional security
considerations.
