Digital Libraries

What is a digital library?"Digital libraries are organizations that

provide the resources, including the specialized staff, to select, structure, offer intellectual access to, interpret, distribute, preserve the integrity of, and ensure the persistence over time of collections of digital works so that they are readily and economically available for use by a defined community or set of communities“ (Digital Library Federation, 1999).

What can you tell about the purpose of the following digital libraries?

What type of materials do they hold?

What points of access do they offer to these materials?

Digital Libraries: Implications

What information do you need to store to support each of these sorts of access? Geospatial co-ordinates Educational levels Author/ publisher Title

Digital Libraries: Metadata

“Metadata is data about data. The term refers to any data used to aid the identification, description and location of networked electronic resources.”

Variety of schemas design to meet local needs but be able to interoperate on some level with other digital libraries Examples: MARC 21; DC; IEEE LOM

Digital Asset Management

Digital Libraries are one type of digital asset store; what are the others?

Loosely speaking two archetypes digital library and content management

Guideline differences between digital library and content management – structured intellectual access, priority of distribute,

Largely same skill set and issues

Digital Asset Management: Mandate Introduction

Year–long project examining digital asset management in Further Education (Nov 04 –Nov 05)

Purpose To inform the FE sector about good practice

and preservation issues Funding

JISC Outcomes

a toolkit for digital asset management in FE and case study of its application at John Wheatley College

Digital Asset Management : Strategy Purpose of an asset management strategy

Who is it for? Staff Students Public

What is it for? Management Access Preservation

What is it going to manage? College documents [y] College learning materials [y] External assets [y] Research materials Finance documents Personnel documents

Page 22: When Is A Digital Library Not A Digital

Digital Asset Management : Strategy Development of an digital asset management

strategy What has to happen to achieve this strategy?

What issues are implicit in these purposes? What issues are implicit in the selection of asset types?

What are the existing people, practices, and structures? How are these assets managed currently? How can existing structures be incorporated /used? What data already exists electronically? Why is being aware of this important?

The system supports the strategy not the other way around (if you build it without them, they will not come).

Page 23: When Is A Digital Library Not A Digital

Digital Asset Management : Metadata Metadata requirements

What points of access are required? What other information is required?Bibliographic (e.g. "a picture of the Eiffel tower taken by

Bob") Administrative (e.g. "taken on 19/04/2005") Legal (e.g. "all rights reserved") Preservation (e.g. "requirement to view as jpeg") Technical (e.g. "jpeg format" ; "85.8kb file") Educational (e.g. "an illustration of construction using cast

iron"; "UK Education Level 11") Structural (e.g. "single file") What of the above metadata is essential? What of the above metadata is secondary

(optional or removed)?

Page 24: When Is A Digital Library Not A Digital

Digital Asset Management : Implementation Who is the best agent to create each of

these metadata elements? What resources are available? Do the available resource require

compromises in the strategy or the metadata?

Page 25: When Is A Digital Library Not A Digital

Digital Asset Management : Exercise Within FE what do you think could be

generalised about: the purpose of a digital asset management

strategies? the asset types involved? the key points of access? the general context?

Page 26: When Is A Digital Library Not A Digital

Digital Asset Management : context Issues for digital asset management in FE (sample

answers) Purpose of institution

Teaching – strategy and system must support and not hinder teachers

Resources available Limited - integration with existing practices vital; human

overhead of using system must be minimal Use of materials

Key points of access – tie into course, educational as well as bibliographic description

Shelf-life of materials Course life; external determined typically < 3 years Curation beyond this is in conflict with the purpose of the

institution Ownership of materials

Blanket policy – college’s property

Page 27: When Is A Digital Library Not A Digital

Conclusions

Skills and issues in construction and operation of systems for digital asset management are generally similar to library and information science skills needed for digital libraries

Digital asset management / digital library design – revolves around key questions of context, resources, and needs
