4. What is De Digitale Stad - The Digital City (1994-2001)?
• 1st (free) public domain virtual city in the world.
• 1st Dutch online community.
• 1st time internet (free) accessible to general public in the Netherlands.
• Grounded by a fluid group: independent media, hackers and the municipality of Amsterdam.
• Attracted international interest for the design: metaphor of a city to structure cyberspace.
• Good for the cyberreputation of the city of Amsterdam:
• CNN (1997): "For hundreds of years the city of Amsterdam has been a center of commercial trade, art and education.
Now it’s helping point the way in the information revolution too".
• Manuel Castells (The Internet Galaxy, 2001): "The most famous citizen computer network. (…) A new form of public
sphere combining local institutions, grassroots organisations, and computer networks in the development of cultural
expression and civic participation".
• Inhabitants (users): 1994: 12.000 - 1997: 60.000 - 1998: 80.000 - 2001: 150.000.
• Houses (homepages): 1996: 3.300 - 1997: 6.500 - 1998: 2.500 - 2001: 782

5. Help! Our digital heritage is getting lost!
• "The world’s digital heritage is at risk of being
lost” and "It’s preservation is an urgent issue of
worldwide concern”, UNESCO in ‘Charter on the
preservation of the digital heritage’ (2003).
• "The Web was not designed to be preserved. The
average life of a Web page is about 100 days“,
Brewster Kahle, Internet Archive.
• “Humanity’s first steps into the digital world could
be lost to future historians. We face a "forgotten
generation, or even a forgotten century”, Vint
Cerf.

6. Out of the box, collection 2.0
• The Amsterdam Museum had to cross boundaries and get out of its comfort-zone to break
new ground in dealing with digital heritage. To seek out new technologies, and new
disciplines.
• New areas: Different demands in acquiring and preservation of digitally created expressions
of culture or physical objects.  How to preserve digital objects that are interactive,
networked, process-oriented and context-dependent?
• E-culture: Data are the new clay, scripts are the new shovels and the web is the youngest
layer of clay that we mine. Web archaeology is a new direction in e-culture in which we
excavate relatively new (born-digital) material, that has only recently been lost, with
relatively new (digital) tools. Both matter and methods to excavate and reconstruct our
digital past are very young and still developing.
Project ‘DDS Revives’

7. The Digital City: important heritage for Amsterdam
• Digital objects bring the story of Amsterdam to life
• The Amsterdam Museum has a long relationship with DDS
• The Digital City as a -pilot- digital object
• Why DDS?
– DDS marks a point in history
– DDS illustrates the role of Amsterdam in the Internet revolution
– DDS history has something typical Amsterdam
– DDS makes the development of Internet touchable
• Why do we do it again?
– Contributing to museum renovation
– Cooperation takes us further
– The importance of participation and co-creation
• The Digital City will definitely come alive!
• DDS can be preserved as heritage and DDS will contribute to bringing
the history of Amsterdam to life!

9. Challenges of born-digital heritage
• Material: information is complex and transitive by nature. By rapid obsolescence of
technology: missing hardware and software, lost documents and link rot. Dynamic character:
doesn’t always reach final status and often not clear what belongs to the object. Ethical
issues: regarding to privacy, copyright and licensing.
• Methodes: there is a difference between web archiving and web archaeology. Web
archiving is the equivalent of taking a photographic snapshot of an object, while we first
aim to recreate the digital object itself. And then: dynamic web archiving!
• Division of tasks: what we *badly* need is:
o Developing of web archaeological tools.
o Central repository for tools: for example to read obsolete media.
o Software library: who is archiving old software like Solaris, Windows, MacOs.
o Sustainable e-depot and infrastructure.
o Approach: no standards: given the urgency we can not wait. So just do it ... and trial and
error!
Project ‘DDS Revives’

10. Treasury with born-digital heritage
• DDS is an important historical source about the early years of the Web in
the Netherlands.
• Culture: DDS is a digital environment, a virtual city with inhabitants, which
brought forth objects, ideas and traditions.
• Technology: DDS is a complex information system with different
applications, through time. DDS is interactive, networked process-based
and context-dependent:
– 1994-1995: DDS 1.0 - telnet interface
– 1994-1995: DDS 2.0 - website: static HTML
– 1995-2001: DDS 3.0 - web system: static HTML and interactive web pages
DDS 1.0 - 15 January 1994 DDS 3.0 - 10 June 1995
DDS 2.0 - 1 October 1994

12. Project ‘DDS Revives’
Start: what do you do?
1. Start:
• Make a plan, develop strategy, document, blog, search partners
• Launch an Open History Lab and virtual museum
2. Excavate:
• Collect stories, memories and data
• Crowdsource & engage the community (Grave Diggers Party
(parties: plural!) & go to your audience: use social media)
3. Reconstruct:
• Analyse & make data readable/accessible
• Develop/deploy web archaeological tools
• Reconstruct DDS: 'historical true' & 'quick and dirty‘
4. Complete the collections:
• (Dynamic!) Archive DDS data in e-depots
• Let the Bytes Free & open it up to the audience: presentation!
5. Finish:
• Conclusions, evaluation, documentation, knowledge sharing

13. Goals of the project ‘DDS Revives’
• Reconstruct and preserve DDS;
• Provide insight into the (existing and new) processes, techniques and methods for born-
digital material and the context in which they are found, to excavate and reconstruct;
• Ask attention to the danger of ‘digital amnesia’;
• Provide museums and organizations with specialized knowledge about the reconstruction of
born-digital heritage and lower the threshold for future web archaeological projects.
Disseminating knowledge about new standards for archives on the storage of digital-born
heritage.
• Make digital cultural heritage DDS ‘future-proof’:
• Visible (content): promoting (re)use of DDS
• Usable (connection): improving (re)use of DDS collection by making it available by linking and enriching data.
• Preservable (services): maintain DDS sustainable and keep it accessible.

Project ‘DDS Revives’

19. Excavate: Collect stories, memories and data
Ask the experts (former users/inhabitants/creators):
• The appearances of the homepage
• Excerpts from the Metro (the Digital Underground)
• Terminals, servers, pictures of the first inhabitants, their avatars, the interfaces, the ideas suggested
• DDS running at Netscape on PCs of that time.
• All bytes that I'm lost
• Special things that are on photo's of the meetings. A coaster, a T-shirt etc
• The old site. As a tribute
• The ability to chat as in the time of DDS
• Large boards of DDS interface, a working DDS, a circle with computers where you can log in again and as
many DDS'ers :) You might also like to exhibit the homes of the residents, with the profiles
• Actually the atmosphere. But that will be difficult
• The Stone Age Computer.
• DDS 3.0 operating
• Bruine Kroeg (virtual bar)

27. Complete the collections: research
• From raw data to e-depot. How to preserve digital objects that are interactive, networked,
process-oriented and context-dependent? Using the Open Archive Information System
(OAIS):
o Ingest: How to read DDS data into an archive and what agreements can be made?
o Archival Storage: Which archives are reliable for the DDS data and how should the data be stored?
o Data management: How should DDS data be managed and which metadata are required?
o Administration: Who takes care of the maintenance, and what does that look like?
o Preservation planning: How do DDS data remain accessible in the future and how to manage this?
o Access: How can interested people get to the DDS data?
• How to present the DDS born-digital heritage in a museum context for future generations?
Project ‘DDS Revives’

28. Complete the collections: preserve and present
From excavation to e-depot: three preservation scenario’s:
1. Bit preservation. Only storage of excavated data: saving the ones and zeros without
sustainability actions. This backup can be used to create a reconstruction in the future.
2. Sustainable storage as dark-archive (= the master, designated community, read only).
Dynamic storage of all excavated and reconstructed DDS data. Starting point: full
preservation; storage of bits and preservation planning and action if necessary.
3. Sustainable storage ánd access. Dynamic storage of excavated and reconstructed DDS
3.0 data with two sub-scenarios:
o Providing access from the e-Depot
o Create a derivative variant for museum presentation
o The first benefits of long-term access, the second for the benefit of immediate use

29. THANK YOU!!!!!
“Please do make sure that colleagues and contributors are made
aware of the impressive impact of their efforts and the high
regard with which we hold your work”. - William Kilbride, DPC
Because:
•The collaboration with the University of Amsterdam and also
with the community that used the website. That they were able
to dig out that data is extremely impressive.
•It preserves rich culture *and* it tells others how they can do it
too. But fundamentally this is a project all about people - at the
start, middle and end - and sometimes we forget this.
•This is an innovative and exciting project.

30. LOST & FOUND: DDS in the museum!
