Internet-Drafts are working documents of the Internet Engineering Task Force (IETF), its areas, and its working groups. Note that other groups may also distribute working documents as Internet-Drafts. Internet-Drafts are draft documents valid for a maximum of six months and may be updated, replaced, or obsoleted by other docu- ments at any time. It is inappropriate to use Internet-Drafts as reference material or to cite them other than as ``work in progress.'' To learn the current status of any Internet-Draft, please check the ``1id-abstracts.txt'' listing contained in the Internet- Drafts Shadow Directories on ftp.is.co.za (Africa), nic.nordu.net (Europe), munnari.oz.au (Pacific Rim), ds.internic.net (US East Coast), or ftp.isi.edu (US West Coast). Distribution of this document is unlimited. Abstract This document defines the expression of Whois++ protocol (originally defined in [RFC1835], updated in [draft-asid-whoispp-02.txt]) responses within MIME [RFC2046] media types. The intention of this document, in conjunction with [draft-daigle-wppresp-00.txt] 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).

Daigle leslie@bunyip.com 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 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 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" 3.
