Network Working Group L. Daigle Request for Comments: 2958 Thinking Cat Enterprises Category: Informational P. Faltstrom Cisco Systems Inc. October 2000 The application/whoispp-response Content-type Status of this Memo This memo provides information for the Internet community. It does not specify an Internet standard of any kind. Distribution of this memo is unlimited. Copyright Notice Copyright (C) The Internet Society (2000). All Rights Reserved. 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.

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 Daigle & Faltstrom Informational [Page 2]
