All Rights Reserved.Abstract   This document describes a Uniform Resource Name (URN) namespace that   is engineered by Network Solutions, Inc. for naming people and   organizations.1. Introduction   In many cases Network Solutions' maintained directory applications   require some unique and persistent way to talk about an individual or   organization.  For example, white pages style services need to   determine if one entry is distinct from another even if some of the   data happens to be the same.  Also, e-commerce authentication   mechanisms needs to identify a user and/or company uniquely and   possibly over large spans of time.  In many cases a customer   relationship can last several decades.  Such long term customer   relationships can outlast any specific email address, Internet   service provider, surname, or possibly even the DNS itself.   The intent for these applications is that they be used and integrated   into other, non-NSI maintained applications in much the same way that   domain-names that exist in Network Solution's database are primarily   used in application that Network Solutions is _not_ involved in.  In   much the same way that ISBNs are maintained by specific entities but   used in widely varying applications, NSI's PIN namespace is intended   to be used in many applications where there is a need for a well   maintained identifier that names a person or organization.Mealling                     Informational                      [Page 1]

RFC 3043                 NSI PIN URN Namespace              January 2001   A URN namespace is uniquely suited to solve the persistent   identification needs of these applications since they are also   required to be unique and persistent.  The availability of a   standardized resolution mechanism makes it possible for other   applications to reference and resolve PIN URNs in their own systems   in an open, non-proprietary way.   This namespace specification is for a formal namespace.2. Specification Template   Namespace ID:       "pin" requested.   Registration Information:       Registration Version Number: 1       Registration Date: 2000-09-30   Declared registrant of the namespace:       Network Solutions       505 Huntmar Park Drive       Herndon, VA 22070   Declaration of structure:       The structure of the NSS is a flat space of alphanumeric         characters which have no knowable structure outside of the         context of Network Solutions internal resolver.  Future changes         to the assignment methods may allow others to assign         sub-spaces of the flat namespace but again, this knowledge is         only valid internally and should never be inferred or relied         upon externally.   Relevant ancillary documentation:       None   Identifier uniqueness considerations:       Identifiers are assigned by Network Solutions proprietary         registration system in a way that guarantees uniqueness.  At         this time the algorithm is to iterate from the last assigned         number by some positive integer.  In the future this algorithm         may change to incorporate a full range of alphanumericMealling                     Informational                      [Page 2]

RFC 3043                 NSI PIN URN Namespace              January 2001         elements.  In either case, the system will compare the newly         created identifier with all of the previous ones to ensure         that it has not already been assigned.   Identifier persistence considerations:       The assignment process guarantees that names are not reassigned         and that the binding between the name and the person or         organization is permanent, regardless of any personal name         changes, corporate restructuring, death or dissolution.   Process of identifier assignment:       Names are granted via Network Solutions proprietary registration         procedures.   Process of identifier resolution:       PIN URNs are resolved via URN resolvers run by Network         Solutions.  Since a PIN URN identifies a person or         organization, resolving a PIN URN will only be able to return         information from an electronic proxy that is merely a         representation of the actual person or organization being         named.   Rules for Lexical Equivalence:       The entire URN is case-insensitive.   Conformance with URN Syntax:       There are no additional characters reserved.   Validation mechanism:       None additional to resolution specified   Scope:       GlobalMealling                     Informational                      [Page 3]

RFC 3043                 NSI PIN URN Namespace              January 20013. Examples   The following examples are not guaranteed to be real.  They are   listed for pedagogical reasons only.      URN:pin:bs4321234      URN:pin:324kj5hkj45      URN:pin:mm21364. Security Considerations   Since the URNs in this namespace are opaque there are no additional   security considerations other than those normally associated with the   use and resolution of URNs in general.   It is noted however that attempting to resolve a PIN URN through a   resolver other than the one provided by Network Solution is error   prone.  In any case it is not considered authoritative.References   [1]  Moats, R., "URN Syntax",RFC 2141, May 1997.Author's Address   Michael Mealling   Network Solutions, Inc.   505 Huntmar Park Drive   Herndon, VA  22070   US   Phone: +1 770 935 5492   EMail: michaelm@netsol.com   URI:http://www.netsol.comMealling                     Informational                      [Page 4]
