Key Idea #1: Graph representation
Socrates

Mortal
Inference “A man is mortal, Socrates is a
man, Therefore Socrates is
mortal”
Query “Find all mortal in Greece where

Semantic Web
Key Idea #2 : everything is a resource, everything can be
linked and has a : URI
every knowledge can be defined
using triplets (subject, predicate, object).
RDF
Predicate
doc.html has Fabien as an
author
Doc.html has music as a
theme
doc.html author Fabien
doc.html theme Musique
doc.html
Musique

Open Data & Linked Data

5 star deployment scheme suggested by Tim Berners-Lee
Open Data & Linked Data
http://5stardata.info/
5 star deployment scheme suggested by Tim Berners-Lee
make your stuff available on the
Web (whatever format) under an
open license
Open Data & Linked Data
http://5stardata.info/
make it available as structured data (e.g.,
Excel instead of image scan of a table)
5 star deployment scheme suggested by Tim Berners-Lee
Open Data & Linked Data
http://5stardata.info/
use non-proprietary formats (e.g., CSV
instead of Excel)
5 star deployment scheme suggested by Tim Berners-Lee
Open Data & Linked Data
http://5stardata.info/
use URIs to denote things, so that
people can point at your stuff
5 star deployment scheme suggested by Tim Berners-Lee
Open Data & Linked Data
http://5stardata.info/
link your data to other data to provide
context
