Internet-Draft Ryan Moats draft-ietf-schema-whois-00.txt AT&T Expires in six months April 1998 A MIME Content-Type for WHOIS Filename: draft-ietf-schema-whois-00.txt Status of this Memo This document is an Internet-Draft. 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 documents at any time. It is inappropriate to use Internet- Drafts as reference material or to cite them other than as ``work in progress.''

Abstract This document defines a MIME directory profile [1] for holding a WHOIS [2] schema and is intended for communication with the Internet schema listing service. The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in RFC 2119 [3]. 1. Overview The document defines how a MIME type may be used to transfer a single WHOIS schema definition. Although [2] specifies the result as non- machine readable it should be realized that the returned object is simply text. Schemas created from this specify the parsing of the text. Therefore an example of how a to register a WHOIS schema is presented. Expires 10/31/98 [Page 1]
INTERNET DRAFT Mime Content for WHOIS April 1998 2. Example MIME Directory Type Registrations This document defines an example whoisSchema used in the "schema- whois-example-0" profile. 2.1 whoisSchema To: ietf-mime-direct@imc.org Subject: Registration of text/directory MIME type whoisSchema Type name: whoisSchema Type purpose: To represent an example WHOIS schema Type encoding: 8bit Type valuetype: text, encoded according to the BNF of section 2.1.1 Type special notes: Each value of this type specifies the contents of a WHOIS schema definition. A definition of all attributes in the schema MUST be present in the content containing this value. Intended usage: COMMON 2.1.1 whoisSchema Syntax Definition Values of whoisSchema are represented according to the following BNF: whoisSchema = "(" whsp attribute-line *[whsp "$" whsp attribute-line] whsp ")" attribute-line = *[ "line:" whsp attr *[whsp "$" whsp attr] attr = 1*utf8 All attributes have text values. It should be noted that this definition is not intended to handle all formatting circumstances nor is intended for complete machine parsing. 3.0 Example From: whomever@wherever.com To: Someone@somewhere.com Subject: schema information MIME-Version: 1.0 Message-Id: <ids1@wherever.com> Content-Type: text/directory; profile="schema-whois-0";charset="utf-8" Content-Transfer-Encoding: Quoted-Printable whoisSchema: ( line: Lastname $ Firstname $ Handle $ Email $ line: Address1 $ line: Address2 $ line: City $ State $ Zip $ line: Phones $ line: null $ line: Record-Last-Updated $ Expires 10/31/98 [Page 2]

Security Considerations A MIME body part containing a text/directory may be incorporated in a digitally signed MIME content, which can be used to verify that the body part has not been modified in transit. When the signer has been certified by a trusted third party service, it may also be possible to verify the origin of the content. 5.
