    types and formats, external content,
    current situation, challenges
   Role of libraries
   Resources
What is an Intranet?
   Private and secure internal information
    system which uses Internet technology
    to collect and disseminate information
    of interest to all staff

           Company
             network              Internet

                       Firewall


          Web
          browser                            Web
                                             browser
What is an Intranet?
   Behind the firewall
   Take advantage of all the open standards and
    protocols that have emerged from the
    Internet (TCP/IP, HTTP, SMTP, Java,
    JavaScript, XML…)
   Web based applications with corporate
    control
   Combination of the ease of use of the
    Internet with the security of a private
    network
Technology behind Intranets
   One or more inter-connected TCP/IP
    networks
   Internet connectivity with firewall
    protection
   Servers: Web, E-Mail, Proxy, DNS
   Browsers, plug-ins, authoring tools
   Databases, CGI tools, search engines
   Website administration tools
Intranet VS Internet
   Internet                    Intranet
       External websites           Internal websites
       E-Commerce                  Commutation &
       Insecure                     Information access
       TCP/IP                      Secure
       Limited management          TCP/IP
                                    Managed
Why Intranets?
   Ubiquitous access to staff
   Improved internal communication
   Improved access to information
   Improved productivity
   Promote user participation
   Improved management
Why Intranets?
   Open platform architecture - plenty of add-on
    applications available

    migrated to the desktop using Web
    technology
   Faster information delivery at lower costs
   Relatively quick and easy to set up
   Scaleable: start small, and grow as needed

An Example Intranet
Another Example…
                          Integration


                  Shared Data


       Intranet
                           Firewall     Internet


 PCs
                           Servers
What is a web site?
   Non-technical view: A computer on the
    Internet/intranet providing access to its
    information store through web browsers
   Technical view: One or more computers
    providing access to variety of web compatible
    documents using HTTP protocol (web
    servers)
       PC, RISC-based workstations/ servers
       Win‟95, Unix, Win‟NT
   Dedicated Internet/intranet connectivity
What is a web site? ...
   Has a unique web site address in the URL
    format
       e.g. http://www.iisc.ernet.in, http://www.nic.in
   Documents stored in a web site are uniquely
    identified using the URL scheme:
       access protocol://host.domain [:port]/path/file
        name
        (e.g. http://www.ncsi.iisc.ernet.in/new.html)
   Document formats:
       HTML, PDF, images, animations, audio, video,
        multimedia presentations, searchable databases,
        etc.
What is a web site? ...
   HTML pages integrate the information
    content served by the web site
       Organized in a hierarchical manner
       Home page (root page) provides links to second
        level HTML pages which in turn link to third level
        HTML pages, and so on
       These pages may contain images and provide
        access to databases through search forms, PDF
        files, audio and video, etc. or link to documents on
        other servers
What is a web site? ...
Websites to Intranets to
Information Portals
   Beginning: External websites
       Promote company and its products
   Later: Intranets
       Use Internet technologies for web enabling
        internal information & communication
   Today: Information Portals
       Integrate internal and external information
        via the Web
Intranet Information Portals
   Aka: Enterprise Information Portals
   Area of recent growth and rapid development
   “EIPs are applications that enable companies
    to unlock internally and externally stored
    information, and provide users a single
    gateway to personalized information needed
    to make informed decisions”
Content Management
   Key issue today in most enterprises
   Why?
       Wide variety of web-enabled digital content
       Web enabling of businesses
       Digital publishing
            Most authoring tools support saving in web compatible
             formats
       Ease of web publishing and hosting
       Need for integrating internal and external content
    What is Content Management?
Technologies, standards, principles and
practices related to:
 Content creation,        Rights management
capturing, publishing      Version control

 Organization and         Administration
storage                    Integration with external
 Search, retrieval and   content
delivery                   Integration with other
 Preservation            applications

Content Management in
      Intranets:
Typical Current Situation
Who Is Creating Content?
   Almost everyone!
   Most from business processes
   Ubiquitous authoring tools – integrated
    with business processes
   Libraries bring most of the external
    content
   Individual surfing, downloads
Where It Resides?
   Distributed across the intranet
   Individual desktops
   Division/ dept. servers, websites

   Very little quality control
   Poor integration
How Is It Being Accessed?
   Visiting individual sites
   File finding tools, shared disk drives
   Reliance on people‟s memory
   Individual bookmarks
   Asking colleagues around
   No central search engines or poor
    search results – lack of context in
    search results
Poor Content Management:
Consequences
   Do not know what exists
   Do not know where something exists
   Lack of confidence in available data –
    enough contextual information not
    available
   Too much of information

    results
   Bring uniformity and consistency in content
    authoring, publishing and presentation
   Provide personalized services
Role of Libraries

       Static to dynamic websites
       Subject gateways
   Bring external content to the intranet desktop
       Databases, e-journals, e-books, software, free
        content
Role of Libraries
   Expertise in metadata handling
