Dave Raggett - Meeting on September 16th 2009

W3C Fellow, Dave Raggett, presented some slides, entitled "New
Directions for the Web". He covered a number of topics including,
delegation, the Web of Things, privacy and context. The general
feeling was that we have a number of technologies to tackle these
issues, such as P3P, OpenID and Oauth, however that the field was
still very much in its infancy. Dave is also part of the W3C Context
Awareness and Personalisation Working Group, which follows on from the
Ubiquitous Web Applications Working Group, and aims to create patterns
and ontologies for dealing with context and personalization, on the

Moving on to questions, Dave suggested that it would be advantageous
to have liaison between groups, so that we can try to achieve a
unified vision. He thought that privacy was perhaps a more key issue
than identity, and that we should learn lessons about usability from
existing projects such as P3P, looking at what works, and more
importantly what doesn't. For example usability was a drawback for
P3P, which prevented it reaching its full potential. On privacy, new
cryto techniques such as Zero Knowledge Proofs should also be
examined. One key aim suggested was to prevent vocabulary
fragmentation, for example, the Delivery Context Ontology could be
mapped with others in the area, however we use tools such as Protege,
but this is an area where we should aim to be become more
collaborative, and ideally the toolset should evolve accordingly.
