One Web!
Founded and directed by inventor of the Web, Tim Berners-Lee
Search is…
Identification

Geolocation API Specification (W3C Candidate Recommendation)
What the user sees or hears

W3C Points of Interest (POI) Working Group
The user's friends
Contacts API (W3C Working Draft)
What the user has
(car, computer, music, purchases, …)

How to contribute to Web standards
Use the existing standards!
(unused standards are not standards)
Provide test cases or use cases
(testing is a requirement to solve interoperability problems)
Participate in on-going developments
(helps speed things up)
Suggest new technology
(see next slide)
In particular, contribution is not restricted to suggesting new technology based on project's results.
Bringing new work to W3C
Next possible search-related standards?
(plausible or not)
More device APIs (e.g. speech input tag)
Interactions with social networks
Attention Profile Markup Language (APML)
Metadata format for Web applications to ease discovery
Best practices to write metadata in media content
Guidelines on privacy
Work on Web identity
Conclusion
Open Web standards at W3C
Search has different facets (identification, indexation, context)
Different ways to contribute to standardization
Work on new standards depends on expressed needs
