Overview What is NEDLIB and why should we care? How does NEDLIB relate to DSEP? How does DSEP relate to OAIS? Expected duration of the project Project outcomes 22 April 2004

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 22 April 2004

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 22 April 2004

How does DSEP relate to OAIS? A readable overview diagram. 22 April 2004

How DSEP relates to OAIS? (Gory details.) (Prepare to be blinded.) 22 April 2004

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: 7 – delivery and capture 8 – packaging and delivery 22 April 2004

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 22 April 2004

How did it turn out? (Part un.) Home: http://www.kb.nl/coop/nedlib/ “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. …” 22 April 2004

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 (?)

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 22 April 2004

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.
