Copyright Notice Copyright (C) The Internet Society (2005). Abstract This document describes a Uniform Resource Name (URN) namespace for the identification of resources in the Pacific And Regional Archive for Digital Sources in Endangered Cultures (PARADISEC) archive. This namespace will provide persistent means of accessing the archives contents allowing for reliable citation. 1. Introduction and Community Considerations PARADISEC is a partnership between four major Australian universities which exists to ensure the long term survival of languages and cultures that may have otherwise been forgotten by history. With an increasingly large amount of research papers being produced citing information within the PARADISEC archive it is important that they have an identifier scheme which encourages the persistence of these citations and therefore the communities ongoing ability to access them. The PARADISEC URN namespace is intended as a means of providing online resource access to linguists, students and other interested individuals in a persistent manner. 2. Specification Template Namespace ID: "paradisec" requested. Registration Information: registration version: 1 registration date: 2005-05-01 Declared registrant of the namespace: Luke Brown ANU Supercomputing Facility Building 56, Australian National University ACTON, ACT, Australia, 0200 Email: lpb900@anusf.anu.edu.au Declaration of syntactic structure: The Pacific And Regional Archive for Digital Sources in Endangered Cultures (PARADISEC) Namespace Specific String (NSS) conforms to the URN Syntax specification [1] and takes the form: URN:PARADISEC::: The PARADISEC NSS adheres to the following ABNF [3] definition: NSS = Collection / Item / File Collection = DIGIT / ALPHA / reserved Item = DIGIT / ALPHA / reserved File = DIGIT / ALPHA / reserved reserved = "/" / "." / "-" / ":" Relevant ancillary documentation: Further information on the PARADISEC project can be located at http://www.paradisec.org.au/ Identifier uniqueness considerations: The PARADISEC curators assign unique identifiers to all resources which are added to the archive. Identifier persistence considerations: PARADISEC identifiers are never reassigned and location independent to facilitate persistence. Process of identifier assignment: Identifiers are assigned by PARADISEC curators upon submission of materials into the PARADISEC archive by linguists. Process for identifier resolution: Resolution of PARADISEC URNs will be achieved through an extension of the DDDS [2] approach. This extension allows for per-resource resolution of URNs using the DNS. Rules for Lexical Equivalence: PARADISEC URNs are not case sensitive. Conformance with URN Syntax: The PARADISEC syntax extends the invalid character set in [1] further prohibiting use of the following: "!", "@", "#", "$", "%", "^", "&", "*", "(", ")", "+", "=", "[", "]", "{", "}", "|", "\", ";", "'", """, "<", ">", "_" and "?" Validation mechanism: None specified outside of the data ingestion procedure. Scope: Global. 3. Security Considerations No new security considerations are presented. 4. IANA Considerations This document includes a URN Namespace registration request to be entered into the IANA registry for URN NIDs. 5.
