Introducing the Project NEDLIB
N E D L I B

• depository task has to expand to include
  electronic information
• project initiated by CoBRA in 1998
• co-funded by EC
• Networked European Deposit Library
• national libraries and archive
• publishers

Aims of NEDLIB
N E D L I B

• generate technical and functional information
• produce a common model and terminology
• raise awareness and promote a joint approach
• review, develop and exchange good practices
• test tools

NEDLIB results
N E D L I B

• guideliness
• overview of the NEDLIB results
• a help to set up a DSEP
• reports on specific issues
• standards for implementing a DSEP
• metadata for long term preservation
• about using emulation for preservation
• standards for electronic publishing
• joint approach
• defining the problem and finding solutions

Guidelines take 6 steps
N E D L I B

• 1 rise to the challenge
• 2 adopt a paradigm use the workflow for
  printed material as starting point
• 3 learn from others
• 4 take a generic approach
• 5 use a common model and terminology
• 6 define the deposit system as a separate
  system and integrate it as a separate entity in
  the existing digital environment

The challenge
N E D L I B

• from paper-based to electronic economy
• we have to build digital deposit stores
• digital information is more vulnerable to time
  than paper-based information
• we have to act NOW
• digital world has a short memory
• reliance on memory organizations will be heavier

EC Telematics for Libraries Programme
7
The paradigm
N E D L I B

• a stack for the electronic collection
• parameters ltgt stack for printed books
• well defined environmental conditions
• strictly controlled access
• maintaining condition of the publication
• binding or restoration
• microfilming
• storage capacity
• calculating and planning

Vulnerability of digital information
N E D L I B

• digital information is used more and more
• in society and research
• in business and private
• there is NO continuity of digital information
• information technology changes fast and as a
  consequence digital information gets inaccessible
  
• a technological (functional) solution has not yet
  been developed to maintain access
• migration (conversion) does not suffices

12
Digital information
N E D L I B

• difference in appearance and content
• handheld or offline, networked or online
  publications, digitally born, digitised
  publications, static, dynamic publications,
  web-documents (hyper linked) etc.
• text, music, pictures, movies, multimedia etc.
• in spite of the differences they consists of
• a series of coded bits
• a key / mechanism to read the code

EC Telematics for Libraries Programme
13
Achieving digital continuity
N E D L I B

• just two things needs to be done
• maintain the chain of coded bits (content)
• copy timely to fresh or new media
• certificate that the copy is authentic
• maintain the key to decode (mechanism)
• preserve (a reference to) the key
• preserve the key / the mechanism

A scene in the year 2015
N E D L I B

• suppose you need a digital article or picture
  produced in the year 2002
• the publication or picture has at that time been
  stored using a special software program ?
• you click on the ? file (a copy of the coded
  bitstream and specific metadata)
• via the ? metadata the decoding mechanism is
  automatically provided as a plug-in
• you can read the article or view the picture

EC Telematics for Libraries Programme
15
The program ?
N E D L I B

• ? is a program providing the functionality for
• authentication of the copy of the bitstream
• capturing the metadata about
• the content
• the code used and the technical environment
• the decoding mechanism
• metadata are as a rule captured automatically and
  occassionally by manual input

EC Telematics for Libraries Programme
16
The state of the art
N E D L I B

• standards are developed
• for implementing a DSEP
• standards for electronic publishing
• metadata are studied
• for the long term preservation
• for using emulation for preservation
• program ?
• solutions being tested (emulation, uvc)
• deposit systems
• developed and implemented compliant with the
  standards at the BL and the KB by IBM

17
Still to be done
N E D L I B

• develop and implement deposits
• for the digital documents
• for representation information and software
• make arrangements for the depositing
• of digital documents
• of the representation information and software
• link the deposits for transparent use
• create and implement the ? functionality
• using standardized metadata
• using cross-border ICT-solutions
