The Semantic WebPrinciples
I Building blocks are very simple!
I Describing resources with Resource Description Framework
Subject the resource being describedProperty denotes traits or aspects of a resource
Object the associated resource
e.g.
<Joe Bloggs> age "40"<Joe Bloggs> friend <Harry Hill><Hary Hill> location <Edinburgh>

I Unique Resource Identifier’s represent thingshttp://www.serena.ac.uk/users/robstewart
I The same thing can have many URIs.

Linked Open DataHow do I find it?
The Data Hub is a community-maintained catalogue of datasets,managed by the Open Knowledge Foundation.
http://thedatahub.org/
Of these, the current 327 datasets making up the LOD cloud arelisted here:
