                 Scheme Specification for the pwid URI
                    draft-pwid-uri-specification-02

Abstract

   This document specifies a Uniform Resource Identifier (URI) for
   Persistent Web IDentifiers to web material in web archives using the
   'pwid' scheme name.  The purpose of the standard is to support
   general, global, sustainable, humanly readable, technology agnostic,
   persistent and precise web references for such web materials.

   The PWID URI ca assist in two ways: First, by providing potential
   resolvable precise and persistent reference scheme for documents,
   which is not sufficiently covered by existing web reference
   practices.  Second, by providing a standardized way to specify web
   elements in a web collection also known as web corpus.  Definitions
   of web collections are often needed for extraction of data used in
   production of research results, e.g. for evaluations in the future.
   Current practices today are not persistent as they often use some CDX
   version, which vary for different implementations.

1.  Introduction

   The purpose of the PWID URI is to represent general, global,
   sustainable, humanly readable and technology agnostic web archive
   resource references - in a scheme that can be used for technical
   solutions.  The motivation for defining a PWID URI scheme is the
   growing challenge of references to web resources, - both regarding
   referencing web resources from papers and regarding definition of web
   collection/corpus.

   o  Citation guidelines generally do not cover general and persistent
      referencing techniques for web resources that are not registered
      by Persistent Identifier systems (like DOI [DOI]).  However, an
