The physical web

http://en.wikipedia.org/wiki/Semantic_Web

The term was coined by Tim Berners-Lee for a web of data that can be processed by machines. It extends the network of hyperlinked human-readable web pages by inserting machine-readable metadataabout pages and how they are related to each other, enabling automated agents to access the Web more intelligently and perform tasks on behalf of users.

The Semantic Web, as originally envisioned, is a system that enables machines to “understand” and respond to complex human requests based on their meaning. Such an “understanding” requires that the relevant information sources be semantically structured.

Nearly all of the roughly 50 petabytes (a petabyte is 1,024 terabytes) of data available on the Internet were first captured and created by human beings—by typing, pressing a record button, taking a digital picture or scanning a bar code. The problem is, people have limited time, attention and accuracy—all of which means they are not very good at capturing data about things in the real world.

If we had computers that knew everything there was to know about things—using data they gathered without any help from us—we would be able to track and count everything, and greatly reduce waste, loss and cost. We would know when things needed replacing, repairing or recalling, and whether they were fresh or past their best.

We need to empower computers with their own means of gathering information, so they can see, hear and smell the world for themselves, in all its random glory. RFID and sensor technology enable computers to observe, identify and understand the world—without the limitations of human-entered data.
