Reflections at 20 years on the state of the WWW

Foci:

1. Web Applications
2. Open Social Networking
3. Open Linked Data

Changes

• Search and SEO such a science
• Advertizing a science too.
• Web years 2.6 now tends to 1?
• Move to Mobile
• Web Apps computing platform
• Linked Open Data movement

Changing environment

• Dropping cost of pixels, glasses etc
• Mobile in developing countries
• Masses of data out there

Same

• Static web of archived HTML and PDF documents
• Need for read-write web
• One Web - use standards!

1. Web Apps

• Serious new computing platform
• Needs serious clean trust system
  • (cabability based - Caja?)
• Needs decentralized modular installation
  • Webized debian?
• Privacy: Geolocation is the tip of the iceberg.

Modularity in general

• Essential for extensibility
• Being part of an as yet unknown larger system
• HTML is a big language -- but not the only one.
• Everyone (inc. IE) implement SVG
• Extensibility using javascript implementation
  • script in page -> installed javascript -> installed compiled code (?)
  • Doesn't work for everything

2. Open Social Networking

• Walled gardens all over again (AOL, Prodigy...; WAP...)
• I want my data back!
• Some open APIs
• Linked Data with policy-aware access control
• Get the power of reuse

Social Silos

Social Silo problem

Open Social Networking

Identity - Personas

Webize -> use URIs

OpenId quite deployed

FOAF+SSL has advantages

Secure Web Id

Beware assumptions about pseudonymity

3. Linked Open Data movement

Linked Data everywhere

• Government (e.g. Obama)
• Enterprise
• Science
• Social networks
• Community (e.g OpenStreetMap, linkedgeodata.org)

Linked Data challenges

• Easy wizard for existing RDB users
• Delegated/Federated SPARQL
• Co-reference -- community based?

Social concerns

• Tracking provenance
• Not just access control, but acceptable use
• Accountable systems
• Read-write socially-aware storage + javascript?

Web I would like

• Clean modular extensible technology
• Seamless interlinked documents and data
• Dataset metaindex => Answer an arbitrary query
• Intimate integration of data and UI with programming languages
• Great security model for Web Applications

Our role

• Build a platform for others that follow
• Do not assume what they will use it for
• Do our bit, others will do theirs.
