I wrote this up for discussion purposes, as a response to some of the discussion about URNs, URIs, and the difference between abstractions and resources that describe them. The discussions have been on many mailing lists (in the "to" list). However, in the interest of reducing the number of duplicate messages, I suggest not cc'ing all of these lists in subsequent discussions. -----Original Message----- From: nsyracus@cnri.reston.va.us On Behalf Of Internet-Drafts@ietf.org Sent: Friday, August 24, 2001 3:43 AM To: IETF-Announce: Subject: I-D ACTION:draft-masinter-dated-uri-00.txt A New Internet-Draft is available from the on-line Internet-Drafts directories. Title : 'duri' and 'tdb': URN Namespaces based on dated URIs Author(s) : L. Masinter Filename : draft-masinter-dated-uri-00.txt Pages : Date : 22-Aug-01 This document defines two persistent namespaces of URNs based on prepending a date to an (encoded) URI. The results are namespaces in which names are readily assigned but which offer the persistence of reference that is required by URNs. The first namespace (duri) is used to refer to URI-identified resources themselves, while the second namespace (tdb) is used to refer to abstractions that are not themselves networked resources but are 'described by' them. This idea and things like it have been discussed for several years, but recent discussion about use of URIs and URNs for identifiers in XML-based constructs has inspired writing this up more completely. A URL for this Internet-Draft is: http://www.ietf.org/internet-drafts/draft-masinter-dated-uri-00.txt Internet-Drafts are also available by anonymous FTP. Login with the username "anonymous" and a password of your e-mail address. After logging in, type "cd internet-drafts" and then "get draft-masinter-dated-uri-00.txt". A list of Internet-Drafts directories can be found in http://www.ietf.org/shadow.html or ftp://ftp.ietf.org/ietf/1shadow-sites.txt Internet-Drafts can also be obtained by e-mail. Send a message to: mailserv@ietf.org. In the body type: "FILE /internet-drafts/draft-masinter-dated-uri-00.txt". NOTE: The mail server at ietf.org can return the document in MIME-encoded form by using the "mpack" utility. To use this feature, insert the command "ENCODING mime" before the "FILE" command. To decode the response(s), you will need "munpack" or a MIME-compliant mail reader. Different MIME-compliant mail readers exhibit different behavior, especially when dealing with "multipart" MIME messages (i.e. documents which have been split up into multiple messages), so check your local documentation on how to manipulate these messages.
