Finding Anything in the Billion Page Web• Panel session on “Finding Anything in the Billion Page
Web: Are Algorithms the Key?”
• Panelists from Excite, AltaVista (Compaq) and Yahoo!
• Hardware is not a significant barrier
• Improved software algorithms will be important. E.g• Citation analysis (cf Google)• User profiles• Specialist search engines (implies 2-layer searches)
• Search engine vendors may discard embedded metadata
• Search engine vendors may make use of trusted third-party metadata
• Conclusions in line with UK HE’s interests!

Need for accessibility audit of institutional web sites?
Need for institutional guidelines / incorporation into training programmes, etc?
W3C Track
NOTE: Gave talk on Accessibility and Metadata at WAI meeting after WWW8 conference. Does metadata have a role to play in providing machine-understandable definitions relating to accessibility? Should user profiles consider accessibility aspects?

SMIL
SMIL:• Synchronized Multimedia Markup Language - an
XML application
• Players (e.g. RealNetworks G2) and authoring tools available
• Microsoft have proposed HTML+ Time (scripting rather than declarative implementation)
• SMIL 2.0 may include MS’s proposals• See <http://www.w3.org/Talks/1999/0513-smil-www8/>
• See <http://www.w3.org/AudioVideo/>• Michael Wilson (RAL) to give talk on SMIL at
Web Manager’s workshop in Sept

HTML
Challenges facing HTML: Poor quality markup
New kinds of browsers: TVs, PDAs, phones, etc
Pressure to subset HTML for simple clients
Pressure to extend HTML for richer clients
Combining HTML with other tag sets: Math, Vector Graphics, E-commerce, Metadata, ...
XHTML• Reformulation of HTML in XML
• TIDY will help
• See <http://www.xhtml.org/>
See <http://www.w3.org/Talks/1999/05/www8-html/sldie1.html>

Other Comments
Appears to be a slowing down in development of protocol and data formats
• Increasing complexity and inter-dependence means more time must be spent in reviewing work of other working groups (cf XML and RDF Schemas)
• Patent and IPR concerns (CSS, XLink, P3P)
• HTTP/NG work seems to be slowing down
