The Rise of Web 3.0
Week 7
![Page 2: CCT300 – Critical Analysis of Media Thursday, October 21, 2010 CCT300 – Labs The Rise of Web 3.0 Week 7](https://reader035.vdocuments.mx/reader035/viewer/2022062515/56649f525503460f94c76412/html5/thumbnails/2.jpg)
When the web was in its early days,
we didn’t know exactly what to show
on a computer screen.

A company card?

A call to action?
![Page 5: CCT300 – Critical Analysis of Media Thursday, October 21, 2010 CCT300 – Labs The Rise of Web 3.0 Week 7](https://reader035.vdocuments.mx/reader035/viewer/2022062515/56649f525503460f94c76412/html5/thumbnails/5.jpg)
A button ?
![Page 6: CCT300 – Critical Analysis of Media Thursday, October 21, 2010 CCT300 – Labs The Rise of Web 3.0 Week 7](https://reader035.vdocuments.mx/reader035/viewer/2022062515/56649f525503460f94c76412/html5/thumbnails/6.jpg)
A shop?
![Page 7: CCT300 – Critical Analysis of Media Thursday, October 21, 2010 CCT300 – Labs The Rise of Web 3.0 Week 7](https://reader035.vdocuments.mx/reader035/viewer/2022062515/56649f525503460f94c76412/html5/thumbnails/7.jpg)
We call this period web 1.0.
![Page 8: CCT300 – Critical Analysis of Media Thursday, October 21, 2010 CCT300 – Labs The Rise of Web 3.0 Week 7](https://reader035.vdocuments.mx/reader035/viewer/2022062515/56649f525503460f94c76412/html5/thumbnails/8.jpg)
Web 1.0 was all about our search
for online viability.
![Page 9: CCT300 – Critical Analysis of Media Thursday, October 21, 2010 CCT300 – Labs The Rise of Web 3.0 Week 7](https://reader035.vdocuments.mx/reader035/viewer/2022062515/56649f525503460f94c76412/html5/thumbnails/9.jpg)
When we got a grip on the technical part,
the real possibilities of the web became
more clear.
![Page 10: CCT300 – Critical Analysis of Media Thursday, October 21, 2010 CCT300 – Labs The Rise of Web 3.0 Week 7](https://reader035.vdocuments.mx/reader035/viewer/2022062515/56649f525503460f94c76412/html5/thumbnails/10.jpg)
We discovered the power of networks.
![Page 11: CCT300 – Critical Analysis of Media Thursday, October 21, 2010 CCT300 – Labs The Rise of Web 3.0 Week 7](https://reader035.vdocuments.mx/reader035/viewer/2022062515/56649f525503460f94c76412/html5/thumbnails/11.jpg)
The power of links
![Page 12: CCT300 – Critical Analysis of Media Thursday, October 21, 2010 CCT300 – Labs The Rise of Web 3.0 Week 7](https://reader035.vdocuments.mx/reader035/viewer/2022062515/56649f525503460f94c76412/html5/thumbnails/12.jpg)
The power of collaboration
![Page 13: CCT300 – Critical Analysis of Media Thursday, October 21, 2010 CCT300 – Labs The Rise of Web 3.0 Week 7](https://reader035.vdocuments.mx/reader035/viewer/2022062515/56649f525503460f94c76412/html5/thumbnails/13.jpg)
The power of content and reach
![Page 14: CCT300 – Critical Analysis of Media Thursday, October 21, 2010 CCT300 – Labs The Rise of Web 3.0 Week 7](https://reader035.vdocuments.mx/reader035/viewer/2022062515/56649f525503460f94c76412/html5/thumbnails/14.jpg)
The power of friends
![Page 15: CCT300 – Critical Analysis of Media Thursday, October 21, 2010 CCT300 – Labs The Rise of Web 3.0 Week 7](https://reader035.vdocuments.mx/reader035/viewer/2022062515/56649f525503460f94c76412/html5/thumbnails/15.jpg)
This is what we call web 2.0.
![Page 16: CCT300 – Critical Analysis of Media Thursday, October 21, 2010 CCT300 – Labs The Rise of Web 3.0 Week 7](https://reader035.vdocuments.mx/reader035/viewer/2022062515/56649f525503460f94c76412/html5/thumbnails/16.jpg)
Web 2.0 is all about the power of
networks.
![Page 17: CCT300 – Critical Analysis of Media Thursday, October 21, 2010 CCT300 – Labs The Rise of Web 3.0 Week 7](https://reader035.vdocuments.mx/reader035/viewer/2022062515/56649f525503460f94c76412/html5/thumbnails/17.jpg)
Basically, web 2.0 is a social change. The
technical part of the web hasn’t changed
very much.
![Page 18: CCT300 – Critical Analysis of Media Thursday, October 21, 2010 CCT300 – Labs The Rise of Web 3.0 Week 7](https://reader035.vdocuments.mx/reader035/viewer/2022062515/56649f525503460f94c76412/html5/thumbnails/18.jpg)
But, web 3.0 will be driven by
technological changes.
![Page 19: CCT300 – Critical Analysis of Media Thursday, October 21, 2010 CCT300 – Labs The Rise of Web 3.0 Week 7](https://reader035.vdocuments.mx/reader035/viewer/2022062515/56649f525503460f94c76412/html5/thumbnails/19.jpg)
Web 3.0 - the semantic web - is about
the meaning of data.
![Page 20: CCT300 – Critical Analysis of Media Thursday, October 21, 2010 CCT300 – Labs The Rise of Web 3.0 Week 7](https://reader035.vdocuments.mx/reader035/viewer/2022062515/56649f525503460f94c76412/html5/thumbnails/20.jpg)
Suppose, I am a stamp collector...
![Page 21: CCT300 – Critical Analysis of Media Thursday, October 21, 2010 CCT300 – Labs The Rise of Web 3.0 Week 7](https://reader035.vdocuments.mx/reader035/viewer/2022062515/56649f525503460f94c76412/html5/thumbnails/21.jpg)
Over the years I’ve collected a lot of
stamps.
![Page 22: CCT300 – Critical Analysis of Media Thursday, October 21, 2010 CCT300 – Labs The Rise of Web 3.0 Week 7](https://reader035.vdocuments.mx/reader035/viewer/2022062515/56649f525503460f94c76412/html5/thumbnails/22.jpg)
About every stamp, I made a
document
![Page 23: CCT300 – Critical Analysis of Media Thursday, October 21, 2010 CCT300 – Labs The Rise of Web 3.0 Week 7](https://reader035.vdocuments.mx/reader035/viewer/2022062515/56649f525503460f94c76412/html5/thumbnails/23.jpg)
That’s a lot of documents
But…
![Page 24: CCT300 – Critical Analysis of Media Thursday, October 21, 2010 CCT300 – Labs The Rise of Web 3.0 Week 7](https://reader035.vdocuments.mx/reader035/viewer/2022062515/56649f525503460f94c76412/html5/thumbnails/24.jpg)
How will I find that specific stamp?
?
![Page 25: CCT300 – Critical Analysis of Media Thursday, October 21, 2010 CCT300 – Labs The Rise of Web 3.0 Week 7](https://reader035.vdocuments.mx/reader035/viewer/2022062515/56649f525503460f94c76412/html5/thumbnails/25.jpg)
Ah, of course !
![Page 26: CCT300 – Critical Analysis of Media Thursday, October 21, 2010 CCT300 – Labs The Rise of Web 3.0 Week 7](https://reader035.vdocuments.mx/reader035/viewer/2022062515/56649f525503460f94c76412/html5/thumbnails/26.jpg)
This is the web we have today: a huge
collection of documents
![Page 27: CCT300 – Critical Analysis of Media Thursday, October 21, 2010 CCT300 – Labs The Rise of Web 3.0 Week 7](https://reader035.vdocuments.mx/reader035/viewer/2022062515/56649f525503460f94c76412/html5/thumbnails/27.jpg)
The words of all those documents are
indexed. We can search for keywords.
![Page 28: CCT300 – Critical Analysis of Media Thursday, October 21, 2010 CCT300 – Labs The Rise of Web 3.0 Week 7](https://reader035.vdocuments.mx/reader035/viewer/2022062515/56649f525503460f94c76412/html5/thumbnails/28.jpg)
Now, suppose I search for all red
stamps…
![Page 29: CCT300 – Critical Analysis of Media Thursday, October 21, 2010 CCT300 – Labs The Rise of Web 3.0 Week 7](https://reader035.vdocuments.mx/reader035/viewer/2022062515/56649f525503460f94c76412/html5/thumbnails/29.jpg)
What do I get ?
Red stampsStamps from Cambodia (Khmer Rouge)Stamps from the Red SeaStamps from the 140 th anniversary of the Red CrossStamps with red dragons
![Page 30: CCT300 – Critical Analysis of Media Thursday, October 21, 2010 CCT300 – Labs The Rise of Web 3.0 Week 7](https://reader035.vdocuments.mx/reader035/viewer/2022062515/56649f525503460f94c76412/html5/thumbnails/30.jpg)
Not very intelligent, but how can a
computer know what I mean?
![Page 31: CCT300 – Critical Analysis of Media Thursday, October 21, 2010 CCT300 – Labs The Rise of Web 3.0 Week 7](https://reader035.vdocuments.mx/reader035/viewer/2022062515/56649f525503460f94c76412/html5/thumbnails/31.jpg)
Answer: when we structurally
describe that a stamp is a stamp and
red is a color.
![Page 32: CCT300 – Critical Analysis of Media Thursday, October 21, 2010 CCT300 – Labs The Rise of Web 3.0 Week 7](https://reader035.vdocuments.mx/reader035/viewer/2022062515/56649f525503460f94c76412/html5/thumbnails/32.jpg)
Describing data in a structured way
can best be done in a database.
![Page 33: CCT300 – Critical Analysis of Media Thursday, October 21, 2010 CCT300 – Labs The Rise of Web 3.0 Week 7](https://reader035.vdocuments.mx/reader035/viewer/2022062515/56649f525503460f94c76412/html5/thumbnails/33.jpg)
Different databases can be connected.
![Page 34: CCT300 – Critical Analysis of Media Thursday, October 21, 2010 CCT300 – Labs The Rise of Web 3.0 Week 7](https://reader035.vdocuments.mx/reader035/viewer/2022062515/56649f525503460f94c76412/html5/thumbnails/34.jpg)
A database with stamps
A database with countries
A database with colours
A database with stamp traders
![Page 35: CCT300 – Critical Analysis of Media Thursday, October 21, 2010 CCT300 – Labs The Rise of Web 3.0 Week 7](https://reader035.vdocuments.mx/reader035/viewer/2022062515/56649f525503460f94c76412/html5/thumbnails/35.jpg)
Web 3.0 creates a big collection of
databases which can be connected on
demand.
![Page 36: CCT300 – Critical Analysis of Media Thursday, October 21, 2010 CCT300 – Labs The Rise of Web 3.0 Week 7](https://reader035.vdocuments.mx/reader035/viewer/2022062515/56649f525503460f94c76412/html5/thumbnails/36.jpg)
Agreements are made on the structure
of data and the way data is described.
Where the data is located is irrelevant.
Linking data is the power of web 3.0.
![Page 37: CCT300 – Critical Analysis of Media Thursday, October 21, 2010 CCT300 – Labs The Rise of Web 3.0 Week 7](https://reader035.vdocuments.mx/reader035/viewer/2022062515/56649f525503460f94c76412/html5/thumbnails/37.jpg)
So, “I want all the red stamps,
designed in Europe, but used in the
U.S.A., between 1980 and 1990” is a
question that will get a better answer
with web 3.0.
![Page 38: CCT300 – Critical Analysis of Media Thursday, October 21, 2010 CCT300 – Labs The Rise of Web 3.0 Week 7](https://reader035.vdocuments.mx/reader035/viewer/2022062515/56649f525503460f94c76412/html5/thumbnails/38.jpg)
This definition of web 3.0 is a ‘narrow’
definition. Like web 2.0, web 3.0 stands
for a range of developments.
![Page 39: CCT300 – Critical Analysis of Media Thursday, October 21, 2010 CCT300 – Labs The Rise of Web 3.0 Week 7](https://reader035.vdocuments.mx/reader035/viewer/2022062515/56649f525503460f94c76412/html5/thumbnails/39.jpg)
A broader definition of web 3.0:A fast broadband connection to the internet, always and everywhere .
Open source techniques and free data (Data as a Service)
Open identities
Software as a Service (e.g. Google docs)
