A fellow WOMMA attendee (Matt from http://www.thegrandunion.com) sent me a precis of Tim Berners-Lee's speech at Oxford Uni last night. He spoke of the concept of the Semantic Web  - a new age of the WWW where all data is ordered by a common standard and 'described' in a way any application can understand. From the W3C site which says it better:

"The Semantic Web is about two things. It is about common formats for interchange of data, where on the original Web we only had interchange of documents. Also it is about language for recording how the data relates to real world objects. That allows a person, or a machine, to start off in one database, and then move through an unending set of databases which are connected not by wires but by being about the same thing."

Blogs are making inroads here with common feed formats as well as content tags which help to describe that content for users. Although a small step in the direction of the SW, what a change they have made already to the way we all access information.

The mind boggles.
