Abstract

This document defines the expression of Whois++ protocol (RFC1835) responses within MIME (Multipurpose Internet Mail Extensions) (RFC2046) media types. The intention of this document, in conjunction with RFC 2957 is to enable MIME-enabled mail software, and other systems using Internet media types, to carry out Whois++ transactions.
1.  MIME Registration Information
To: iana@isi.edu Subject: Registration of MIME media type application/whoispp-response

MIME Type name: Application

MIME subtype name: whoispp-response

Required parameters: none

Optional parameters: none

Encoding considerations: Any valid MIME encodings may be used

Security considerations: This content-type contains purely descriptive information (i.e., no directives). There are security considerations with regards to the appropriateness (privacy) of information provided through the use of this content-type, and the authenticity of the information so-provided. This content-type provides no native mechanisms for authentication.

2.  whoispp-response Syntax
The following grammar, which uses ABNF-like notation as defined in [RFC2234], defines a subset of responses expected from a Whois++ server upon receipt of a valid Whois++ query. As such, it describes the expected structure of a whoispp-response media type object.

N.B.: As outlined in the ABNF definition, rule names and string literals are in the US-ASCII character set, and are case-insensitive.
      server          =   goodmessage mnl output mnl endmessage nl
                          / badmessage nl endmessage nl

      output          =   full / abridged / summary / handle
full = 0*(full-record / server-to-ask)

abridged = 0*(abridged-record / server-to-ask)

summary = summary-record
      handle          =   0*(handle-record / server-to-ask)
full-record = "# FULL " template serverhandle localhandle
system-nl
1*(fulldata system-nl) "# END" system-nl

abridged-record = "# ABRIDGED " template serverhandle localhandle
system-nl
abridgeddata "# END" system-nl
