The State of the Web

The web is strong

The web is evolving

The web has been good to us

The web is a key to our future success

Evolution of the Web

© 2007 UCAR RAL

A Good Beginning

1963 "Hypertext"

1990 First Web Site (NeXTcube at CERN)

First Web Browser (“WorldWideWeb”)

1993 Mosaic Browser

1994 W3C founded

© 2007 UCAR RAL

A Mediocre Middle1997 HTML 4.0 and DOM

1998 XML 1.0

1999 “Semantic Web”"I have a dream for the Web [in which computers] become capable of

analyzing all the data on the Web - the content, links, and transactions between people and computers. A 'Semantic Web', which should make this possible, has yet to emerge, but when it does, the day-to-day mechanisms of trade, bureaucracy and our daily lives will be handled by machines talking to machines. The 'intelligent agents' people have touted for ages will finally materialize."

Web 3.0

Vision "People keep asking what Web 3.0 is. I think maybe when you've got an overlay of scalable vector graphics -everything rippling and folding and looking misty - on Web 2.0 and access to a semantic Web integrated across a huge space of data, you'll have access to an unbelievable data resource."

- Tim Berners-Lee,quoted in International Herald Tribune 2006

Another Vision"But if I were to guess what Web 3.0 is, I would tell you

that it's a different way of building applications... My prediction would be that Web 3.0 will ultimately been seen as applications which are pieced together. There are a number of characteristics: the applications are relatively small, the data is in the cloud, the applications can run on any device, PC or mobile phone, the applications are very fast and they're very customizable. Futhermore, the applications are distributed virally: literally by social networks”
