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:
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.
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.

From Web 2.0 to Web 3.0 Web 1.0 = sites, pages, links (static, proprietary, non-interactive) Web 2.0 = people, participation (dynamic, interactive, connecting) Web 3.0 = machines (semantic, linked data, context)15
Semantic web "a web of data that can be processed directly and indirectly by machines” (Tim Berners-Lee) “… provides a common framework that allows data to be shared and reused across application, enterprise, and community boundaries”16

Linked data RDF data that links to other RDF data on the web is Linked data (Linked Open Data)18
What does this mean in construction? 1. Linked data connects and provides context to social interactions and to data about physical world we live in. 2. Building Information Modelling (BIM) will increasingly apply Linked Data principles throughout the BIM lifecycle. Finding and linking relevant, related information will become increasingly19 important.
