Web built on connections between documents...

Data less connected - more siloised.

“the Web done right”
Sir Tim Berners-Lee, 2008
harks back to TimBL’s original vision for a Read/Write Web
cloudofdata.com
Use URIs to name things
Use HTTP URIs so that they can be followed
When someone follows a URI, provide useful information
Include links to other URIs, so that more can be discovered.

Data as Commodity
cut costs, mass produce, standardise - create opportunities for growth
What does this mean for Enterprise?

It’s easier to TRY...

Boundaries blur, walls (like this one) fall.Data and processes move back and forth.Fears eventually diminish.

Closing Thoughts
cloudofdata.com
The Web is about connections
Data today often best connected inside silos
Simple principles of Linked Data create opportunities to manipulate data at Web scale
Licensing frameworks emerging
Understanding of the boundary is required… but worth the effort.
