This talk

Remember back before the Web?
The fundamental change: Universality
Web Science
Linked Data
The other 80%

Pre-Web

now difficult to explain what it was like!

Documentation systems do not work together
Attempts to unify fail from imposing too much
Difficult to explain what WWW will be like

Pre-web at CERN

Need to bridge

People from all over the world
Different sorts of information
Different organizations

1990: WWW design

URI is global identifier, having one is good
URI schemes have different properties
- HTTP scheme allows publish and lookup
- HTTP allows many data formats
  - HTML is a language for hypertext
  - .. but links not typed.

Universality of the Web

Technology which is independent of:

Hardware platform
Software platform - OS
Application Software
Network access
Language and culture
Disability
Documents for people -- or Data for machines
The number of web pages

Access for Anybody

Layers: Separate Markets

Layers: The IP Hourglass

1991-4: Paradigm shift

Increase of 10x every year

1994: World Wide Web Consortium

good + fair + fast

Industry and academic and public participation
Wide review
Implementation Interoperability requirements
Coordination between groups
Internationalization, Accessibility
Royalty free standards -> safe, wide adoption
Many activities, check w3.org
Join!

Leading the web to its full potential

Care and use of the WWW

URIs should be persistent - don't change them!
Make sure your site is accessible
Insist on open standards

Spirit of Web design

has been the best part

Diversity of participants
Openness
Royalty-free foundation => Wide adoption
Sense of excitement, unbounded opportunity
