    Url,purl and doi Url,purl and doi Presentation Transcript

    • URL,PURL and DOI
      Shriram Pandey
      The LNM IIT, Jaipur
    • Background
      Resource Identification- A first step to gain access.
      -Book: ISBN, UPC
      Similar Identification system also require for the digital environment.
    • URL(Uniform Resource Locator)
      It is an address of the resource located anywhere over the Internet.
      Uniform: Unique
      Resource: Anything that has entity
      Identifier: An object that can act as a reference to something that has an identity
    • Component of URl
      Syntax: <scheme>:<scheme-specific-part>
      The scheme may be :
      ftp :File Transfer protocol
      http: Hypertext Transfer Protocol
      https: Hypertext Transfer Protocol Secured
      mailto: Electronic mail address
      telnet :Reference to interactive sessions
      File: Host-specific file names
      Example: http://www.suniv.ac.in
    • Problem Associated with URL
      URL are not persistence and resource can lost, if
      the server moves to a new computer
      the server moves to a new port on the same computer
      the name of the computer the server runs on changes
      the resource's name changes
      the resource moves to a new server
    • The Solutions
      A permanent URL which persistence.
      There are many solutions : PURL, Handle System, DOI etc.
      We shall cover the PURL and DOI in detail.
    • PURL
      PURL(Persistent Uniform Resource Locator)
      A project by OCLC
      Three Component :
      Resolver address
      Example: http://purl.oclc.org/SU/PG_DLIS
    • How PURL Work
    • Digital Object Identifier
      An identification system for intellectual property in the digital environment.
      Developed by the DOI foundation to provide a framework for managing intellectual content, link customers with publisher.
      Provides a persistent identification number to each resource registered with DOI registration agencies.
    • Component of DOI
      DOI Prefix:
      Two component: 10.<organization assigned number>
      DOI Suffix
      Identification for the entity, it may be a number, ISBN etc.
    • DOI Resolution
      Ensures persistence by resolving the DOI to a current associated value such as a URL;
      Resolution may be :
      Simple Resolution
      Multiple Resolution
    • Simple Resolution
    • Multiple Resolution
    • Benefits of DOI Systems
      Persistence, persistence, persistence!!!
      DOIs are easy to use. Simply click one or cut and paste it like you would a URL
      Called the “barcode for intellectual property”
      Multiple resolution capability leads to more options for researchers.
