The technology of information and library

Since Tim Berners Lee invented Web ± with thetechnology of information packaging and friendlygraphical interfaces, the Internet has become the normal

activity, even it is indispensable for everybody in thisplanet in order to meet the need of informationubiquitously

If this invention was known as the cause of the Internetusage explosion and the information explosion, the Webtechnology has impacted very much on the history of information and library. In other words, Web is thetechnology of information and library at present and

in the future.



Open source systems (1)

The Open Source Initiative (OSI), which holds

the trademark to the term open source software,

has the definition:Open source software is not only in terms of the

availability of the source code, but uses criteria that

include free distribution of the application, as well as

provision for the future use of code in modificationsand derived works without discrimination against the

persons or groups involved.



Open source systems (2)

Richard Stallman, a founder of the GNU Project

and a leading figure in the OSS world, identifies

four kinds of freedom for open source application

that are supported by the licensing: T he freedom to run the program for any purpose (freedom 0.)

T he freedom to study how the program works and adapt it to your

needs (freedom 1). Access to the source code is a precondition for

this. T he freedom to redistribute copies so you can help your neighbor

(freedom 2).

T he freedom to improve the program and release your improvement

to the public so that the whole community benefits (freedom 3).

Access to the source code is a precondition for this, too.

The change of cataloging (2)

In traditional libraries, you catalog to create catalog

cards or bibliographic records. In electronic

environment, they are packaged to become

bibliographic metadata, such as MARC 21 has toconvert into MARC-XML

In the developing libraries, the usage of Dublin

Core to catalog entire materials in the library is thegood way. You can apply the open source software

to convert Dublin Core metadata into MARC

records if necessary, such as the data exchanging

via Z39.50 gateway at present.

Web-based cataloging (1)



Web-based cataloging (2)

The process of cataloging:

The database server contains Dublin Core bibliographic

metadata which are created by catalogers and system for

both kinds of materials, print and electronic. Thesematadata will be converted into MARC records and display

on OPAC interface as bibliographic records with descriptive

data of items such as title, author, subject, etc.... The MARC

records retrieved from Z39.50 servers everywhere will be

also converted into Dublin Core to store in the database

servers.

Building full text collections

The full text collections are built by the Greenstone open

source software. Greenstone is a comprehensive

system for constructing and presenting collections of

thousands or millions of documents, including text,images, audio, and video. Easily maintained, collections

can be augmented and rebuilt automatically.

With the assistance from the library, each faculty or

researcher uses Greenstone open source software to

build his own collections and then they are contributed tothe library in order to enrich the learning resource

storage.

Building metadata collections

In the Portal system of Natural Sciences Library, VNU-

HCM there is a module of information retrieval. It is used to

harvest bibliographic metadata based on OAI-PMH (Open

Archives Initiative - Protocol for Metadata Harvesting) from

the URLs supplied by users, then they are built upcollections. Each collection consists of OAI records from

one or many URLs.

The Retrieval Module consists of three main parts: Oracle

Portal, Greenstone, and OAI Protocol. The retrievedmetadata by harvesting are gathered in a Greenstone

collection automatically including 15 elements of Dublin

Core. You can modify them by the Greenstone Librarian

Interface or the file of collect.cfg .

Chat reference

Chat reference supplies the interaction of the

librarian with patrons on the Internet. It consists of

two online services:

Question/Answer for individual Conferencing for many people at the same time

This is the system integrated by Oracle Web

Conferencing ± a product of Oracle used in

information exchanging and e-learning. It suppliesmany features and has friendly interfaces so it is

easy to use.

Chat reference: a conferencing channel



The electronic library information system of

Natural Sciences Library, VNU-HCM in 2007

Three goals:

Building the electronic library information system:

Including three modules: E-Learning

Digital Media System

Digitizing Line.

Building the digital resources storage. Upgrading the information infrastructure.



The electronic library information system of

Natural Sciences Library, VNU-HCM in 2007

The Portal integrated following components:

E-learning: To supply the online environment of teachingand study for about 1,000 students and faculty.

Digital resources management system.

Library management system.

Digitalizing line system.
