Is Web 2.0 Different?

How does Web site preservation differ for Web 2.0:• Use of 3rd party services• Emphasis on collaboration and communication,

rather than access to resources• More complex IPR issues• Richer diversity of services

Let’s look at:• Case study 1 - wikis• Case study 2 – blogs• Case study 3 – reusing data• Case study 4 – comms tools (disposable data)• Case study 5 – recording events

Group Exercises

Speed exercises:• You will be given an example to consider.

Give an initial response, in a single sentence (or word) in less than a minute!

Small group exercise:• In small groups chose an example of

interest. • Give a more considered response to the

preservation challenges

Case Study 1: A Public Wiki

WetPaint wiki used to support various workshopsApproaches 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

Web

2.0

Many aspects of Web site curation are to do with implementing such best practices, rather than implementing technical solutions

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.

Web

2.0

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 2: 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

Web

Web

2.0 Case Study 2: 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) so there’s a need to check transfer mechanisms

Case Study 2: 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, …

Web

2.0

Migration of blogs, wikis, etc. is not currently an easy task But advice is available

Case Study 3: Reusing DataBlog post in Facebook. Possible concerns:

• It’s not sustainable• You’ve given ownership to

Facebook

Web

2.0

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 micro-blogging application

Facebook status messages is another related example

Web

2.0

Issues:• Will Twitter be sustain-

able over a long period?• What will happen to the

data?• What about the IPR for

‘tweets’?• What about institutional

uses?

Case Study 4: Disposable DataW

eb 2

.0

Many twitterers regard their tweets as disposal

I tend to use Twitter as a ‘virtual water cooler’ – sharing gossip, jokes and occasional work-related 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

Web

2.0 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 YouTubeIssues:

• 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 IWMW 2007 videos

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: Social Networks

University of Wales, Newport and University of Bradford have set up Ning networks for supporting their students:

• Bradford: Closed (Bradford email address needed to access)

• Newport: Open Intended for students about to arrive at institution

What does preservation mean in this context?Answers to this question will be left as an exercise for the participants

Role Of The Internet Archive

Can we leave everything to the Internet Archive?

• 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 (currently) access Facebook pages, for example

Role Of The Internet Archive

The Open University has a presence in Facebook. In June 2008:

• 7,551 fans• 983 wall posts• 82 discussion

topicsIs anyone:

• Recording the history?

• Curating the data• Managing

possible risks?

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
