Contents
  • Background The Semantic Web
  • What Is FOAF?
  • Relevance Of FOAF To This Conference And Session
  • The Development Culture Behind FOAF
  • The Limitations
  • Wider Implications

3
About The Semantic Web (1)
  • The Semantic Web
  • Why is it needed?The Semantic Web is needed is
    order to provide a more structured Web in which
    resources can be brought together for a variety
    of purposes
  • What is it?The Semantic Web can be regarded as a
    global distributed database, which can be
    developed without central coordination

4
About The Semantic Web (2)
  • The Semantic Web
  • How is it done?The Semantic Web is an XML
    application which contains a simple mathematical
    model which defines relationships which are
    defined using a URI
  • What are the challenges?The Semantic Web is
    perceived as difficult to understand. These
    apparent difficulties provide a barrier to its
    deployment.

5
Is It Difficult?
  • The mathematical model behind the Semantic Web is
    based on simple tuples, as illustrated

The relationship ('knows' in this case) is
defined at a URI
Is this really conceptually difficult?
6
FOAF A Simple SW Application
  • FOAF
  • Stands for "Friend Of A Friend"
  • Provides structured links about individuals
  • Information distributed extensible
  • Avoids data protection concerns

Me, email,work place, friends
7
FOAF Example (1)
A view of my FOAF file, showing links to my
friends
  • FOAF Explorer - lthttp//xml.mfd-consult.dk/foaf/ex
    plorer/gt

8
FOAF Example (2)
  • FOAFNaut - lthttp//www.foafnaut.org/gt

9
My Aims
  • SW Promotion
  • Promote use of FOAF as a lightweight Semantic Web
    application
  • Enable people to be part of the Semantic Web
  • Community-Building
  • Use a FOAF application which supports
    community-building at events
  • Implementation
  • Joint work with local FOAF geek (Leigh Dodds)
  • Development of tools
  • Use of tools (at IWMW 2004)
  • Paper presented at IADIS WBC 2004

10
Creating FOAF
  • Several types of FOAF authoring tools provided
  • Do it by hand
  • Web-based tools
  • Dedicated tools
  • A Wiki (experimental)

11
A FOAF Application
  • We've got
  • Powerful standards (RDF/FOAF)
  • Simple authoring tools
  • What we need now is
  • Application area to encourage uptake
  • Richer tools for data-mining
  • Application
  • Who attended JISC-CETIS conf 2004?
  • Who's going to JISC-CETIS conf 2005?
  • Who's going and is interested in LIP, LOM, real
    ale,
  • Background
  • Addressed previously but application-specific ?

12
FOAFNaut
FOAFNaut application is being extended to include
visualisation of events data
13
Review FOAF And Events
  • We explored using events (conferences, seminars,
    etc.) to promote SW take-up
  • Delegates often want to establish links with
    people they meet (cf. use of business cards)
  • Encouraging delegates to create their own data
    gets them motivated
  • This also avoids data protection concerns and
    places maintenance of individual
  • Use at technical conferences also provides
  • Feedback
  • Opportunity to get developers engaged in further
    work

14
What Next?
  • What can happen next
  • Further promotion of this concept at other events
  • Encouragement for additional development
  • Dedicated viewing tools
  • Search facilities

Beyond Browsing Find we people who attended WBC
2004 and XML 2004 who have an interest in xxx

15
What Happened?
  • Take-up
  • Promoted at IWMW 2004 (flyer in pack)
  • But few delegates used ( they were the techies)
  • Technologies
  • FOAFNaut support for events has still not been
    included in main version
  • Wiki authoring tool hacked
  • People
  • Develop had other commitments

16
Reflections
  • Some thoughts
  • Privacy issues
  • Branding issues ('he's not my friend')
  • Getting beyond the early adopters
  • Is FOAF more appropriate back-stage (e.g. export
    format in Blogs)?
  • Do we want shrink-wrapped solutions (e.g. Orkut)?
  • Is the interest in the technology too far away
    from users' needs?
  • Has FOAF been a failure or a success?

17
Discussion
  • Questions., comments, etc. welcome
