            A Persistent Web IDentifier (PWID) URN Namespace
                    draft-pwid-urn-specification-07

Abstract

   This document specifies a Uniform Resource Name (URN) for Persistent
   Web IDentifiers for web material in web archives using the 'pwid'
   namespace identifier.

   The main purpose of the standard is to support specification of
   references that are not covered by other reference techniques: to
   support references to material in web archives with restricted
   access.  Furthermore, it supports persistent technology agnostic
   references to web archives in general, in a form that can work as an
   algorithmic basis for finding web archive resources in general.  An
   additional important benefit is that the standard can be used for
   specifying web collections, which can then form a persistent
   computational basis for the extract of the archived collection parts.
   Since these parts can be specified generally, this further allows
   collections to be specified with elements from one or more web
   archives.

   The PWID URN is designed to meet requirements for proper referencing
   needed by researchers.  Therefore, it is designed as general, global,
   sustainable, humanly readable, technology agnostic, persistent and
   precise web references for web materials in web archives.

1.  Introduction

   The PWID URN is a supplement to existing reference standards, where
   the PWID URN will support references to web archives, including areas
   that are not supported today: support of references to material in
   web archives with restricted access.  Furthermore, the PWID URN
   enables technology agnostic references to web archives in general,
   which can be needed, for instance for references to dynamic web
   material with frequent updates (e.g. a news site) or a specific
   version of a web material (e.g. specific version of the DOI
   handbook).

   The PWID URN is in a form which can work as an algorithmic basis for
   finding the resource.  This also enables computation of archived web
   parts to a collection from one or more web archives, if the
   collection parts are specified by PWID URNs.

   Furthermore, the PWID URN includes information about the resource
   which makes it possible to find alternative resources, in cases where
   the original precise resource has become unavailable.
