Knowledge Management

Knowledge?


A collection of data is not information.


A collection of information is not
knowledge.


A collection of knowledge is not
wisdom.


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
knowledge.


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
systems

Functionality


File Synchronization


Metadata


Version control and security

Differences


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.

Metadata

Harvesting Metadata


Two Approaches:



Federated:


No storage needed = High Network Traffic.



Periodic:


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.



Advantages


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.


Space


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


Networking


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

Disadvantages


Cost


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
-
of
-
date and inaccessible due to
technological advances


Hampered by copyright law


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


Some digital libraries work to digitize out
-
of
-
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


Open
-
source vs. proprietary


Costs


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)


Customization


internationalization/multilingual support (languages)

Software Platform: Fedora


Description:
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.


Availability


Free, open source


Distributed under the Mozilla open source license
