Why RDF? self-describing machine readable meaning
What is RDF?
RDF is a model predicate subject object
Is that it?
Yes, that’s it. predicate subject object
The model can be serialized as XML
The model can be serialized as XML It’s pig ugly
The model can be serialized as XML It’s pig ugly That’s fine. Machines eat ugly for breakfast
Honestly, don’t worry RDF != RDF/XML
Our model can describe models
Specific Models
Specific Models About stuff
Specific Models About Things
Specific Models About Things Let’s call these ontologies

Ontologies are described in OWL
Ontologies are described in OWL OWL is modeled in RDF
RDF is machine readable
RDF is machine readable So ontologies can understood by machines

The mechanism for Linking enables the Web to Scale

Why does the Web scale?
REST
A Resource Oriented Architecture
A Resource Oriented Architecture with a simple protocol to return representations of those resources
HTTP returns those representations
HTTP returns those representations When it talks to us, it returns HTML
The resources are simply addressable objects
