Three Blindfolded men and an elephant!
What is the Semantic Web (3)
The Web Done Right(Sir Tim)
What is the Semantic Web (4)
If Web 1.0 was about linking information and Web 2.0 about linking people, the social Web, then Web 3.0 will be about connecting knowledge(Nicked from the LinkedIn Semantic Web Group)
What is the semantic web (5)
Lets be a bit more practical and choose an example domain
Facebook and Social Networks!
Yep, it's audience participation time, How many social network sites can we list all together?
What is the Semantic Web (6)
(Yesterday) Today - Data is controlled by applications, and each application keeps it to itself.
Tomorrow (Today) - Linked web of data
Machine-Understandable Documents
FOAF Friend Of A Friend
FOAF (2)
FoaF is an acronym for Friend of a Friend, an experimental project and vocabulary for the Semantic Web.
It is based on the idea of a machine-readable version of the current World Wide Web, with homepages, mailling lists, travel itineraries, calendars, address books and the likes.

FOAF So What?
Starting point Application agnostic model of People, Friends, Interests Not an application but free to be used in any Application
Extensible!RDF Schemas are not like XML schemas (IMNSHO)
FOAF - So What? (2)
It's not the FOAF Profile itself thats interesting
My FOAF profile(s) are hosted wherever I want
I can have Multiple FOAF profiles BUT link them
- The ability to merge foaf profiles (Forward pointer to merging of graphs, common schema)
- Semantic Spiders - Crawl web looking for application/RDF link elements
HOMEWORK!
Go to
http://www.ldodds.com/foaf/foaf-o-matic
And create yourself a FOAF profile, then upload it to your blog / website / other resource (Or talk to me about other ways of getting it published)
Email me the address of your foaf ([email protected])
This may be useful for next time!
