Useful Data http://www.flickr.com/photos/timothymorgan/75294154/

Integrating with the web creates maximum utility

Three Stages of Web Integration

Stage 1: Publishing Data

Put the Raw Data Online http://www.flickr.com/photos/timothymorgan/75699268/

Organize It, So It Can Be Found http://www.flickr.com/photos/timothymorgan/75288579/

License It, So It Can Be Reused http://www.flickr.com/photos/timothymorgan/75288583/

Stage 2: Web Accessible Data

Use Standard Open Formats http://www.flickr.com/photos/psd/1806223654/

Add a Web API http://www.flickr.com/photos/timothymorgan/75288582/

Stage 3: Integrate with the Web

Identify Things

<http://www.example.org/thing/{id}>

Link Them Together http://www.flickr.com/photos/timothymorgan/75288770/

Wait For (more) Great Things To Happen http://www.flickr.com/photos/timothymorgan/75288586/

Why Not Link the Data Model to the Web?

Identify Properties of Things http://www.flickr.com/photos/timothymorgan/75593157/

<http://www.example.org/property/{id}>

Is there a uniform way to publish both data & model? http://www.flickr.com/photos/timothymorgan/75699268/

RDF

RDF is a Web Native Data Model http://www.flickr.com/photos/timothymorgan/75593157/

Many Ways to Exchange RDF data http://www.flickr.com/photos/timothymorgan/75288583/

RDF/XML, RDF/JSON, RDFa, ... http://www.flickr.com/photos/timothymorgan/75288583/

Linked Data? http://www.flickr.com/photos/timothymorgan/75288772/

Creating Web of Data for People... http://www.flickr.com/photos/timothymorgan/75288585/

...and Machines (browsers, crawlers, ...) http://www.flickr.com/photos/timothymorgan/75593155/

Networked Data creates Network Effects

Quick Review

There are different styles of data publishing

Deeper web integration increases utility

Deeper web integration generates network effects

Linked Data maximises utility
