Introduction to IBM digital library


The first commercial digital library effort in
the United states.


Consists of an array of products and
services to transform information into
digital multimedia.


Includes tools to manage, present and
protect information.

3

Primary Focus


The primary focus is on image retrieval.


Particular emphasis on high quality image
presentation.


Searching capabilities for the multimedia
information.


Copyright and intellectual property
management capability.

The Digital Library


Integrates a wide array of scalable
information into a single architecture using
technologies for:


Storage


Management


search


Retrieval


Distribution

DB
2
Digital library


IBM DB
2
digital library is a
digital asset
management system

for video, audio,
images, and text.



DB
2
transforms multimedia assets into
digital form which can be distributed over
public or private networks.

How does it work???

-

The System

7

Create & Capture


Provides creation of content and capture of
existing materials.


Allows digital content from many diverse
sources to be incorporated into DB
2
.


Integrates high
-
resolution scanning and color
calibration technology to capture and
reproduce images.

8

Storage & Management (
1
)


Provides high
-
performance, scalable storage
and management of information


Openness

-

this is an open framework of
hardware and software which can be
implemented.


Scalability

-

provides a powerful and scalable
technology base, that will grow easily as
needed.


Provides for hierarchical storage management
using disks, tapes, optical storage =
cost saving
.

Storage & Management (

)


The information management features include
automated indexing, foldering, correlation, feature
extraction and translation functions for efficiently
organized items for search.


The heart of the library are servers which manage
catalog information and provide pointers to the objects
held in the collection.


Clients receive a path to the information being held in
object servers.


Objects may be prestored and retried upon request.

10

Search & Access (
1
)


Uses powerful search and access technologies
that help users look at the content to find it
quickly, accurately and intuitively.


Provides content
-

independent data storage that
allows for many kinds of objects to be stored in
a scalable archive.


Uses search technologies that include
sophisticated tools for text and image analysis.

11

Search & Access (
2
)


Offers
natural language query

-

returns a
ranked list with probability of relevance.


Allows users to search a collections media
objects by color percentage, distribution,
position and image texture expressed
graphically.


Expanding to include video searching by
moving image content.

12

Distribution


IBM DB
2
Digital Library is open to the world.


Provides access to users through any existing
computer network.


The information can be viewed and presented
using any computer system with graphical user
interface.


Uses network management software to assist in
digital and analog information delivery.

13

Rights Management (
1
)


IBM concentrates on Rights Management as a
key factor in creating DB
2
Digital Library.


Uses IBM innovations in networking security
and transactions technology.


User identifies, enters a password, requests
information and the system checks against the
user eligibility. Based on the approval, the
information is given.

14

Rights Management (
2
)


Can authenticate original media such as
photos, manuscripts, audio, video…
-

by using electronic signatures, digital
content can be recognized as authentic
with these signatures.


The mark in use now is “Watermark”
-

it can be an electronic or visible mark.

15

DB
2
is a digital library?


Collection of data objects?


Collection of metadata structures?


Collection of services?


Domain Focus?


Quality Control?


Preservation?

{

Depends on the creator and
{

the manager of the library

Does DB
2
answer to the definition of a digital library???

Lets see…

conclusion



IBM DB
2
digital library is
digital library
management:

software and hardware that
supposed to create, manage, store and
maintain the digital library.
