Knowledge Management

A collection of data is not information.

A collection of information is not

A collection of knowledge is not

A collection of wisdom is not truth.

Creating Value

We must manage data about

The past

Info about the organization, its market,
the competition, and

The pattern that relates all these things.

This enables a reliable level of
predictability of the future.

Knowledge Management

Capture, retention, and reuse of

Without “on
demand” access to
managed knowledge, situations are
addressed with only a piece of
everything the organization knows
about a similar situation.

Functionality and Differences of


File Synchronization


Version control and security


Types of files supported

System scalability

User interface customizability

Different categories

Digital Asset Management

provides customizable
views of a stored file.

Content Management Systems

provide a customizable
way to search the content.

Enterprise Content Management

supports the
complete asset life cycle

Enterprise Publishing

creates virtual work groups
sharing content

Electronic Document Capture

helps with the transition
of unstructured paper documents to digital assets.

Brand Resource Management

is focused on
syndication of brand, and maintains brand integrity.

Things to keep in mind when
shopping for a system.

Is it customizable? Molding it to the way
you work is important.

Is it relational? Stored files must have links
to all related media

Is it secure? Control who sees what and
that the information is secure as it travels
among computers.

Is it Flexible? Get client software that
allows access from Macintosh and PC, and
file conversion should be easy so it can be
used on different computers.

Harvesting Metadata

Two Approaches:


No storage needed = High Network Traffic.


Everyday storage = Low Network Traffic.

Digital Libraries

Definition: A library in which a significant
proportion of the resources are accessible
by means of computers.

The digital content may be locally held or
accessed remotely via computer networks.

The use of search engines, Optical Character
Recognition, and metadata allow digital copies of
individual items (i.e. text, images, audio, and
video) to be cataloged and then accessed easily
by authorized personnel in the future.


No physical boundary and round the clock avaiability

Just need an internet connection

Multiple accesses

The same resources can be used at the same time by a number of users.

Structured approach

provides access to much richer content in a more structured manner, i.e. we can
easily move from the catalog to the particular book then to a particular chapter
and so on.

Information retrieval

The user is able to use any search term bellowing to the word or phrase of the
entire collection.

Preservation and conservation

An exact copy of the original can be made any number of times without any
degradation in quality.


have the potential to store much more information, simply because digital
information requires very little physical space


A particular digital library can provide the link to any other resources



costs for the conversion of print materials into digital format

costs for the technical skills of staff to maintain them

Costs of maintaining online access (i.e servers, bandwidth
costs, etc.)

the costs of migrating every few years to the latest digital
media (Hardware and skilled personnel costs)

Reading Ease

Printed material easier on the eyes than reading off of a
computer screen

Data may become out
date and inaccessible due to
technological advances

Hampered by copyright law

The content is, in many cases, public domain or self
content only

Some digital libraries work to digitize out
copyright works
and make them freely available to the public.

Choosing a Software Platform:

Things to consider

File formats supported (text, images, datasets, video, audio, etc.)

metadata standards (descriptive, technical, preservation, rights)

Interoperability (OAI compliance, SRW, Z39.50, etc.)

user authentication and authorization

search/browse of metadata

source vs. proprietary


technical support availability and methods

Fee vs. free

Medium used (by phone, by email, via online forums, etc.)

Scalability (able to grow with the needs of the firm)

backup and recovery

system maintenance

Extensibility (access to other firm resources, systems)


internationalization/multilingual support (languages)

Software Platform: DSpace

DSpace is a digital library
system designed to capture, store, index,
preserve, and redistribute the intellectual
output of a university’s research faculty in
digital formats. It was developed jointly by
HP Labs and MIT Libraries.


Free, open source software

Distributed through the BSD open source

Software Platform: Fedora

Jointly developed by University of Virginia
and Cornell University, Fedora (Flexible Extensible Digital
Object Repository) serves as a foundation for building
interoperable web
based digital libraries, institutional
repositories, and other information management systems.
It demonstrates how you can deploy a distributed digital
library architecture using web
based technologies, including
XML and Web services.


Free, open source

Distributed under the Mozilla open source license

A free online library

Mission: to provide organized access to
high quality, accurate, and truly useful
resources and tools that support
innovations in teaching and learning at all
levels of science, technology, engineering
and mathematics education

The rapid acceleration of info online makes
finding this material challenging without
