Web 3.0
• Web 3 is the brainchild of Tim Berners-Lee, largely
credited for inventing the world wide web in the first
place. It's more commonly called the Semantic Web.
The idea is, to quote Lee, "I have a dream for the
Web [in which computers] become capable of
analyzing all the data on the Web – the content, links,
and transactions between people and computers.A
‘Semantic Web’, which should make this possible, has
yet to emerge, but when it does, the day-to-day
mechanisms of trade, bureaucracy and our daily lives
will be handled by machines talking to machines.The
‘intelligent agents’ people have touted for ages will
finally materialize."

• I'm typing an email to someone, and we're
brainstorming about doing a business
development deal with Apple.A little
window pops up and lets me know that
David over in our Tucscon office is already
having a similar conversation with Apple
and perhaps we should coordinate.

• I'm booked on a flight from Toledo to
Seattle. It's cancelled. My phone knows that
I'm on the flight, knows that it's cancelled
and knows what flights I should consider
instead. It uses semantic data but it also has
permission to interrupt me and tell me
about it. Much more important, it knows
what my colleagues are doing in response
to this event and tells me. 'Follow me' gets
a lot easier.

• I'm late for a dinner. My GPS phone knows
this (because it has my calendar, my
location, and the traffic status). So, it tells
me, and then it alerts the people who are
waiting for me.

20. An email client that is smart
about what I'm doing and
what my opted in colleagues
are doing. Once that gains
traction, plenty of vendors
will work to integrate with
it.

provider that is not just a phone,

• Web 1.0 was the Hypertext/CGI Web. (the
basics)
• Web 2.0 is the Community Web (for
people: apps/sites connecting them).
• Web 3.0 is the Semantic Web (for
machines).
• Web 4.0 is when these technologies come
together to form what I call the “Learning
Web”.
