1 The Rich Web Arnaud Dumont RAL Retreat * Nov 7-9, 2007

2 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

3 Evolution of the Web

4 A Good Beginning 1963 "Hypertext" 1990 First Web Site (NeXTcube at CERN) First Web Browser ( WorldWideWeb ) 1993 Mosaic Browser 1994 W3C founded

5 A Mediocre Middle 1997 HTML 4.0 and DOM 1998 XML 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."

6 A Mediocre Middle 1997 HTML 4.0 and DOM 1998 XML Semantic Web 1999 RSS MSRS 2002 XMLHttpRequest

7 Major Evolution 2004 GMail Google Maps Google Suggest 2005 "AJAX" flickr Netflix

9 How Does It Apply? Innovate with "middle-weight" displays Simplify interaction Create a user experience Think beyond the desktop

10 Decentralized Data

11 Semantic Web Notation RDF subject, predicate, object <urn:states:new%20york> < "NY" OWL Resources Dublin Core Metadata Initiative SPARQL 2007 UCAR RAL

12 Applications MIT's Semantic Interoperability of Metadata and Information in unlike Environments Exhibit Piggy Bank Longwell Linking Open Data project

14 How Does It Apply? Share data ADDS DataServer GIS Climate Change Scenarios Project Composite data WMS/WCS/WFS layers in displays Research data?

15 Future Presentation Devices

16 Consumer Electronics Can't anticipate how people will want to access data Separate formatting from contents Embrace standards

17 How Does It Apply? Prepare for emerging platforms Mobile phones Electronic flight bag DHS first responders In-vehicle displays Be aware of network impacts Bandwidth Asynchronicity Dependencies Storage

18 Architecture of Participation

19 Users Build Content Usenet Perl's CPAN, Apache's Modules Wikis, MySpace/Facebook, flickr, and YouTube Peer-to-peer networks (Napster, BitTorrent)

20 How Does It Apply? Feedback on models Collaboratories User support "cost avoidance" User tracking (Google Analytics)

21 Development Challenges

22 Engineering IP concerns Security Vanishing release cycles Design shift Loosely coupled components Interfaces & SOA

23 How Does It Apply? Plan for maintenance Agile development User-driven testing Release mechanisms

24 Web 3.0

25 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

26 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 -Eric Schmidt, CEO of Google
