3. What is NEDLIB and why should we care?
NEDLIB – Networked European Deposit Library
Eight national libraries
One national archive
Two ICT organizations
Three major publishers
Koninklijke Bibliotheek has lead
Develop common architectural framework
Basic tools for building deposit systems
Implementation vice theory
Opportunity for Jeff Rothenberg to demonstrate the feasibility of his ideas

4. How does NEDLIB relate to DSEP?
DSEP – Deposit System for Electronic Publications
NEDLIB project will define overall DSEP
“… identify functional requirements that are common to all deposit libraries in order to arrive at a ‘generic’ high-level design.”
A common workflow to facilitate discussions and comparison of approaches

7. 5 – regulates everything 6 – unique to DSEP DLS modules:
OAIS modules:
1 – only SIP
2 – only AIP
3 – deals with metadata
4 – more limited
5 – regulates everything
6 – unique to DSEP
DLS modules:

8. Expected duration of the project
Experiment to take place during 1999 and 2000
Results of the experiment
Several reports detailing lessons learned
Software to implement DSEP workflow

9. How did it turn out? (Part un.)
Home:
“An Experiment in Using Emulation to Preserve Digital Publications,” Jeff Rothenberg
“… The results of the initial iteration of the experiment described above indicate that this approach [software emulation of obsolete hardware] should work in principle, assuming that suitable emulators for obsolete computing platforms can be hosted on future platforms. …”

10. How did it turn out? (Part duex.)
“Metadata for the Long Term Preservation of Electronic Publications,” Catherine Lupovici and Julien Massanes
Lists a proposed set of metadata identifiers and their relationship to Curl Exemplars in digital Archives (CEDARS) and National Library of Austria (?) (NLA)
Various other reports and presentations

11. How did it turn out? (Part trois.)
NEDLIB Web Harvester
Visits a set of URLs and harvests files
Results stored in MySQL database
Collects static pages
Handles 97% of page types
Doesn’t handle things like image maps
Difficulty indexing images, sounds, “funny” files

12. Impression of paper
Liked the fact that they were going to do something
Confused by the “two” languages
First half, English was not the writer’s first language
Last half, English was the writer’s first and it read like a direct lift from a proposal
Project left behind interesting software (NEDLIB harvester)
Unsure how the lessons learned were used by anyone.
