Internet Resources Discovery (IRD) IBM DB 2 Digital Library Thanks to Zvika Michnik and Avital Greenberg
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. 2
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. 3
The Digital Library • Integrates a wide array of scalable information into a single architecture using technologies for: – Storage – Management – search – Retrieval – Distribution 4
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? ? ? 5
DB 2 DL - The System 6
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. 7
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. 8
Storage & Management (2) • 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. 9
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. 10
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. 11
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. 12
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. 13
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. 14
DB 2 is a digital library? Does DB 2 answer to the definition of a digital library? ? ? Lets see… • • • 15 Collection of data objects? Collection of metadata structures? Collection of services? Domain Focus? { Depends on the creator and { the manager of the library Quality Control? Preservation?
IBM DL - conclusion • IBM DB 2 digital library is digital library management: software and hardware that supposed to create, manage, store and maintain the digital library. 16
Libraries using IBM DB 2 digital library • The library of Congress • The Vatican Library • The National Library of the Netherlands • Indiana University 17
