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
ToP   noToC   RFC2958 - Page 2
   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.

   Intended usage:         common

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
