Linked data
“... if the past was document sharing, the
future is data sharing” (Tim Berners-Lee)
1. A URL should point to the data.
2. Anyone accessing URL should get data
back.
3. Relationships in the data should point to
additional URLs with data.

Where a Zettabyte is 1024 Exabytes, an Exabyte is 1024 Petabytes and a Petabyte is 1024 Terabytes. A Zettabyte is therefore approximately 10 ^ 21 bytes. That's a data explosion of 44x in approximately 10 years.
What Joe does not point out is the shift from unstructured data to structured data. Presently, 90% of worldwide data is unstructured. However, almost all of the sources of new data which are causing the explosion are structured. (These include social networking, blogging, Twitter, and all of the Web 2.0 content, plus sources like e-readers, PDAs, smart phones, medical / dental digital imaging, online security, smart energy metering and the like.) The result is this graphic showing the relationship between structured and unstructured data going into the future:
Linking Open Data community project is to extend the Web with a data commons by publishing various open datasets as RDF on the Web and by setting RDF links between data items from different data sources. … By September 2011 this had grown to 31 billion RDF triples, interlinked by around 504 million RDF links.
