• the general population has access, in
terms of quality and quantity, to
• the food that they need for adequate
intake and biological utilization
• to ensure a healthy and productive life.”

Interaction
• Radio – talk shows now available on
the Web
• http://www.caribbeannews.com/radi
o.html
• Caribbean Radio on the Net.
• Good potential for sharing
information
Durrant
11
Conferencing
• Web conferencing can be used to
facilitate continuous interaction
among groups.
• Provides links between meetings
Durrant
12
Web Conferencing?
• Facilitates group discussions by
messages stored on a server. It usually
includes various types of real-time, or
synchronous, communication, such as
"chat rooms", and may also include
voice-based teleconferencing, or simple
video conferencing.
• The Web browsers and servers provide
most of the functionality.
Durrant
13
Main strains
• Centralized forums e.g.Yahoogroups,
Web Crossing, dgroups – organized
messages
• Groupware e.g. LOTUS Notes
• Bulletin board systems (BBSs) – no
organization
• Usenet – decentralized storage
• Mailing - email broadcasts

Similar to Yahoogroups but
incorporates networks of supported
development agencies such as
IDRC.

Digital libraries
• The Internet has also begun to
facilitate the development of
digital libraries.
• This means that full-text
collections can be accessible over
the net.
Durrant
20
Digital Libraries
• The concept of digital libraries is
based on
• the development of specialized
collections aimed at particular user
communities.
• full text including video and audio
• accessible via the Internet

Greenstone software
• The Greenstone Digital Library
Software is an application in the
public domain developed to
facilitate
• access to information
• sharing of information across the
Internet
Durrant
23
Greenstone
• Developed by a team at the
University of Waikato with support
of Unesco
• Distribution is facilitated by
Unesco, GNU lisence
• Can be downloaded on the Internet
• http//www.sourceforge.net
Durrant
24
Objectives
• Building
• library collections of documents and
other digital objects
• institutional repositories
• e-theses collections
Durrant
25
Open source
• Open-source software provides an
economical alternative to libraries'
reliance upon commercially supplied
software.
• Still there are costs of documentation,
training and sometimes customization,
and conversion.
Durrant
26
Main required features
– Facilitating networking - ubiquitously
available to libraries;
– capable of being tailored to suit the needs
and circumstances of individual libraries
– documented – printed or online (and
documentation must be available); and
– Usually a user group - errors can more
effectively be identified and corrected (“two
eyes are better than one")

Open standards
•
With OSS the IT infrastructure
that is essential to library
operations and services can be:
–
open (that is, built according to open
standards and as such potentially
inter operable with other essential
software and systems);
