Organizational KM

Background Issue

An Organizational Workflow

5

Organizational KM

• When a new project is launched, we normally investigate whether we know anything about it. – For projects similar to the past, we go to files and

cabinets • to search for the related documents for reference.

– For unfamiliar projects we would spend time researching • either by finding/reading reference books, surfing the net;

and

• consulting senior engineers or experts to come up with a solution.

6

Organizational KM

• This process is time consuming and not very productive if not well facilitated

Digital Library

What is a Digital Library?

• A digital library is an integrated set of services for capturing, cataloging, storing, searching, protecting, and retrieving information (Reddy et al. 1999)

• A digital library typically comprises digital collections, services and infrastructure to support life-long learning, research, scholarly communication and preservation (Wikipedia 2006b).

10

What can it do?

• Original use – Preservation: Archive of digitized copies of rare

documents, books, and historical objects

– For study by people of new generations

• Modern use: Material from MIT’s white paper – Central repository to store virtually all works of

faculty and staff

– Preservation of all works so that they do not vanish with time (and technological obsolescence)

11

Important Terms

• Digital Library

– Institutional Repository

12

Important Technologies

• Greenstone

– Librarian

DSPACE DIGITAL LIBRARY MIT’s Institutional Repository Solution

15

DSpace

• “DSpace is a groundbreaking digital institutional repository that captures, stores, indexes, preserves, and redistributes the intellectual output of a university’s research faculty in digital formats.”

• Developed jointly by MIT Libraries and Hewlett-Packard

• Licensed under BSD distribution license

• www.dspace.org

DSpace

• Supports submission of, management of, and access to digital content

– Formats: text, images, audio, video

• Organized based on organizational needs of a large university

– Communities and collections

17

DSpace Features

• Digital preservation – Persistent IDs, support levels for different file

formats

• Access control • Versioning • Search and retrieval

– Based on qualified Dublin Core metadata

• Plus interoperability with other digital library systems

18

DSpace Technology

• OS: Unix/Linux or Windows

• Written in Java

• PostgreSQL relational database

• Provides complete Web user interface, but Java APIs available

Sources of Knowledge

• Traditional – Discussions with colleagues & experts

• Summarized and blogged

– Experience from past projects • Relevant project files collected & documented

• Web

– Web browsing & Google searches • Someone else’s experience • Datasheets

– Serendipity
