About This Talk
Will use of Web 2.0 services lead to
new preservation concerns? And
how should we respond to these
new challenges?

Web 2.0
Is Web 2.0 Different?
Implications of Web 2.0 for Web site preservation:
• Use of 3rd party services (‘network as platform’)
• Content  collaboration and communication
• Richer diversity of services (not just a file on a
filestore/CMS/database)
• More complex IPR issues
Let’s look at:
• Case study 1 - wikis
• Case study 2 – blogs
• Case study 3 – reusing data
• Case study 4 – comms tools
• Case study 5 – recording events
• Case study 6 – Slideshare
• Case study 7 – Use of video tools
• Case study 8 – social networks

Case Study 1: A Public Wiki
WetPaint wiki used to
support various workshops
Approaches taken:
• Open access to all prior
to & during event (to
minimise barriers to
creating content)
• Access restricted to
WetPaint users after
event
• Access later restricted
to event organisers
Many aspects of Web site curation are to do

Case Study 1: A Public Wiki
WetPaint provides an
option for backing up data.
A zipped file of the pages
can be saved for storing on
a locally managed service.
There are limitations in
this particular service
(poor quality HTML,
internal links don’t work,
…)
But this does illustrate an
approach which can be
taken.

Case Study 2a: Blog Migration
How might you
migrate the
contents of a
blog (e.g. you’re
leaving
college)?
This question
was raised by
Casey Leaver,
shortly before
leaving Warwick
University

Case Study 2a: Blog Migration
She migrated her
blog from blogs at
Warwick Univ to
Wordpress
Note, though, that not all data was transferred (e.g. title, but
not
contents)
there’s
a need
to check transfer mechanisms

Case Study 2a: Blog Migration
A backup of UK Web
Focus blog is
available on Vox:
• Manual migration
of new posts
every few weeks
• Only migrates text
• Doesn’t migrate
images,
embedded videos,
internal links,
comments, …
Migration of blogs, wikis, etc. is not currently an easy task 

Case Study 2b: The Individual’s
Blog (1)
Auricle blog:
• Launched Jan
2004 by head of elearning team, Bath
• High profile &
public visibility by
early adopter &
evangelist
Today:
• It’s gone
• Lost after
evangelist left, new
staff arrive, new
priorities, …

Case Study 2b: The Individual’s
Blog (2)
Auricle reborn:
• Further Google
revealed the blog has
been reborn
• New domain
(www.auricle.org/)
• New engine
(Wordpress) & look
and feel (but old
engine still available)
• New content being
added
• Old content still
accessible

Case Study 3: Reusing Data
Blog post in Facebook.
Possible concerns:
• It’s not sustainable
• You’ve given ownership
to Facebook
Response:
• The post is managed in
WordPress; Fb displays
copy (to new audience)
• Fb don’t claim
ownership – they claim
rights to make money
(e.g. through ads)

Case Study 4: Disposable Data
Twitter – example of a microblogging application
Facebook status messages is
another related example
Issues:
• Will Twitter be sustainable over a long period?
• What will happen to the
data?
• What about the IPR for
‘tweets’?
• What about institutional
uses?

Case Study 4: Disposable Data
Many twitterers regard their
tweets as disposal
I tend to use Twitter as a ‘virtual
water cooler’ – sharing gossip,
jokes and occasional workrelated information with (mainly)
people I know
You could make use of
clients which manage your
tweets (e.g. treat like email)
But you should develop your
policies first, prior to
exploring technologies

Case Study 4: Disposable Data
Skype (or your preferred VoIP
application) are growing in
popularity
Issues:
• Is the digital data (the call)
preserved?
• What about the video and
the IM chats?
Possible Responses:
• Am I bovvered?
• I didn’t bother with
analogue phones, why
should I worry now?

Case Study 5: Digitized Talks
Seminar on Open Science
given at UKOLN in Feb 2008.
Video clip of opening 10 mins
taken & uploaded to YouTube
Issues:
• Privacy
• Quality
• Benefits
• Long term access
Benefits identified – now how do
we seek to deploy recordings of
seminars, conferences, etc. on a
more systematic basis?
This is work in progress – but see

Case Study 6: Slideshare
What happens to your slides if Slideshare disappears?
My approach:
• Master copy held on managed environment
• Info on master on title slide and metadata
• CC licence & download available – many
copies

Case Study 7 – Video Tools
Requirement:
• Provide brief video clips for
colleagues running workshop
• Initial idea – use Seesmic video
micro-blogging service (can
include video responses)
But:
• No video export function (yet)
• Accessibility of responses
Approach taken:
• Create video locally
• Upload video to YouTube (to
allow textual comments)
• Link to managed master file
Seesmic and YouTube Web sites
and Twirl client are access tools; the
data is managed

Case Study 8: Social Networks
http://newstudents.newport.ac.uk/
What does preservation
mean in this context?
Answers to this question will
be left as an exercise for the
participants 
University of Wales,
Newport and University of
Bradford have set up Ning
networks for supporting
their students:
• Bradford: Aimed at
students during their
first term at University
• Newport: Open
Intended for students
about to arrive at
institution

What Do We Do For SNs?
The Open University
has a presence in
Facebook.
On 9 Sep 2008:
• 9,785 fans
• 1,233 wall posts
• 138 discussion
topics
Is anyone:
• Recording the
history?
• Curating the data
• Managing
possible risks?

Role Of The Internet Archive
Can we leave
everything to the
Internet Archive (IA)?
• Has role to play in
Web 1.0
• Seems to archive
some public blogs
• May not access
images or other
embedded content
• Still has limitations
(cf. UCE/BCU)
Can’t access, e.g.,
Facebook pages

The Research Challenges
Some thoughts:
• Preservation of Web sites in
known to be difficult
• Additional difficulties in a
Web 2.0 world
• Complexities include
technical challenges and
business issues
However:
• Is avoiding Web 2.0 a
realistic answer?
• There may be some simple
processes which may help

Accessibility & Preservation
The parallels:
• We can’t release xxx: it breaks accessibility
guidelines; we’ll be sued
• The xxx service provides benefits to many –
we’ll see what reasonable adjustments are
needed to enhance access
Approaches needed:
• Clarification of the purpose of the service
• Risk assessment of loss of service / record
of service / record of look-and-feel
• Documented policy

Conclusions
To conclude:
• Web 2.0 services won’t go away
• Innovation in departments won’t stop
• Motivated & dedicated professional can help in
preservation
• But this can’t be guaranteed
• Need for individual / departmental audits for
asset management strategies when outside
agencies involved?
• But maybe we don’t need to preserve stuff
• Need for education on when stuff may be
transient and disposable
