What is Semantic Web?

What problems does it address

For data, we are pre-web

How does it work?

  1. Apply power of URIs to concepts of relational data
  2. Model real things, not documents or database tables

SW: Everything has a URI

Don't say "colour" say <http://example.com/2002/std6#col>

The relational database

A database's row, column and cell are subject, property and value.

The element of the Semantic Web

arrow tail, body and head are l are subject, property and value.

Semantic web includes tables,...

Arrows can make a table, an arrow from each row to each value

...trees

Arrows can make a table, an arrow from each row to each value

... everything

Arrows can make a table, an arrow from each row to each value

 

2003: Enterprise Application Integration

N by N problem without RDF

RDF: Enterprise Integration hub

N by 1 problem with RDF

Global Integration bus

N by 1 problem with RDF


Applications connected by concepts

Its like a metro, the way the lines of common concepts connect the stations of different applications

Clients of the RDF bus

New data applications can be built on top of RDF bus, for example:

db to sw

Components: Adapting random files

Keep your existing systems running - adapt them

db to sw

Components: Triple store

Virtual severs actually figure stuff out as well as look up data

db to sw

Adapting SQL Databases

Keep your existing systems running - adapt them

db to sw

Adapting XML

Remeber- RDF on an HTTP server can always be virtual

db to sw

Adapting XML: GRDDL

Remeber- RDF on an HTTP server can always be virtual

db to sw

Components: Smart servers

Virtual severs actually figure stuff out as well as look up data

db to sw
