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. 1. MIME Registration Information To: 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 Daigle & Faltstrom Informational [Page 1] RFC 2958 application/whoispp-response Content-Type October 2000 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. Published specification: this document Person & email address to contact for further information: Leslie L. Daigle 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 Daigle & Faltstrom Informational [Page 2] RFC 2958 application/whoispp-response Content-Type October 2000 summary-record = "# SUMMARY " serverhandle system-nl summarydata "# END" system-nl handle-record = "# HANDLE " template serverhandle localhandle system-nl server-to-ask = "# SERVER-TO-ASK " serverhandle system-nl server-to-askdata "# END" system-nl fulldata = " " attributename ": " attributevalue abridgeddata = " " 0*( attributevalue / tab ) summarydata = " Matches: " number system-nl [" Referrals: " number system-nl] " Templates: " template 0*( system-nl "-" template) server-to-ask-data = " Server-Handle:" serverhandle system-nl " Host-Name: " hostname system-nl " Host-Port: " number system-nl [" Protocol: " prot system-nl] 0*(" " labelstring ": " labelstring system-nl) attributename = 1*attrbyte attrbyte = <%d33-127 except specialbyte> attributevalue = longstring template = labelstring serverhandle = labelstring localhandle = labelstring hostname = labelstring prot = labelstring longstring = bytestring 0*( nl ( "+" / "-" ) bytestring ) bytestring = 0*charbyte labelstring = 0*restrictedbyte Daigle & Faltstrom Informational [Page 3] RFC 2958 application/whoispp-response Content-Type October 2000 restrictedbyte = <%d32-%d255 except specialbyte> charbyte = <%d32-%d255 except nl> specialbyte = ":" / " " / tab / nl tab = %d09 mnl = 1*system-nl system-nl = nl [ 1*(message nl) ] nl = %d13 %d10 message = [1*( messagestart "-" bytestring nl)] messagestart " " bytestring nl messagestart = "% " digit digit digit goodmessage = [1*( goodmessagestart "-" bytestring nl)] goodmessagestart " " bytestring nl goodmessagestart= "% 200" messagestart = "% " digit digit digit badmessage = [1*( badmessagestart "-" bytestring nl)] badmessagestart " " bytestring nl badmessagestart = "% 5" digit digit endmessage = endmessageclose endmessageclose = [endmessagestart " " bytestring nl] byemessage endmessagestart = "% 226" byemessage = byemessagestart " " bytestring nl endmessagestart = "% 203" number = 1*( digit ) digit = "0" / "1" / "2" / "3" / "4" / "5" / "6" / "7" / "8" / "9" Daigle & Faltstrom Informational [Page 4] RFC 2958 application/whoispp-response Content-Type October 2000 3.
