Ted Nelson: Web sites are seen as decorated directories.

Our everyday challenge: Build the ideal, hypertext based knowledge portal
![Page 4: Topic Maps 2008](https://reader035.vdocuments.mx/reader035/viewer/2022062405/557c509ad8b42a11668b4e87/html5/thumbnails/4.jpg)
Existing technology has failed to meet expectations regarding the original ideas of hypertext
![Page 5: Topic Maps 2008](https://reader035.vdocuments.mx/reader035/viewer/2022062405/557c509ad8b42a11668b4e87/html5/thumbnails/5.jpg)
Obtain new tools that render possible new solutions
![Page 6: Topic Maps 2008](https://reader035.vdocuments.mx/reader035/viewer/2022062405/557c509ad8b42a11668b4e87/html5/thumbnails/6.jpg)
Topic Maps may be the tool for building these web sites
![Page 7: Topic Maps 2008](https://reader035.vdocuments.mx/reader035/viewer/2022062405/557c509ad8b42a11668b4e87/html5/thumbnails/7.jpg)
Web sites became copies of technical structures
Most of these structures are hierarchical
![Page 8: Topic Maps 2008](https://reader035.vdocuments.mx/reader035/viewer/2022062405/557c509ad8b42a11668b4e87/html5/thumbnails/8.jpg)
To avoid these shortcomings, someone invented the concept of portlets.
Portlets made it possible to place related information beside each other
![Page 9: Topic Maps 2008](https://reader035.vdocuments.mx/reader035/viewer/2022062405/557c509ad8b42a11668b4e87/html5/thumbnails/9.jpg)
They can be seen as aquariums placed beside each other
Looks nice, but there are not necessarily any connections between the content of the two
![Page 10: Topic Maps 2008](https://reader035.vdocuments.mx/reader035/viewer/2022062405/557c509ad8b42a11668b4e87/html5/thumbnails/10.jpg)
Portlets works fine for stock brokers

How is knowledge natively organized?
Nobody knows
![Page 13: Topic Maps 2008](https://reader035.vdocuments.mx/reader035/viewer/2022062405/557c509ad8b42a11668b4e87/html5/thumbnails/13.jpg)
Knowledge is not natively hierarchical
Building hierarchies are skills you learn at school.
![Page 14: Topic Maps 2008](https://reader035.vdocuments.mx/reader035/viewer/2022062405/557c509ad8b42a11668b4e87/html5/thumbnails/14.jpg)
Knowledge is generally understood as concepts associated with each other
The same way Topic Maps are built
![Page 15: Topic Maps 2008](https://reader035.vdocuments.mx/reader035/viewer/2022062405/557c509ad8b42a11668b4e87/html5/thumbnails/15.jpg)
To avoid the shortcomings, content must be separated from presentation
![Page 16: Topic Maps 2008](https://reader035.vdocuments.mx/reader035/viewer/2022062405/557c509ad8b42a11668b4e87/html5/thumbnails/16.jpg)
from here
to here
180 degrees
Find the shortest path!

Presentation is a visual aid to support the understanding of information
![Page 20: Topic Maps 2008](https://reader035.vdocuments.mx/reader035/viewer/2022062405/557c509ad8b42a11668b4e87/html5/thumbnails/20.jpg)
Only separation of content and presentation makes innovation possible
![Page 21: Topic Maps 2008](https://reader035.vdocuments.mx/reader035/viewer/2022062405/557c509ad8b42a11668b4e87/html5/thumbnails/21.jpg)
It should be possible to make different perspectives into the same information..
.. and see the information from different angles
![Page 22: Topic Maps 2008](https://reader035.vdocuments.mx/reader035/viewer/2022062405/557c509ad8b42a11668b4e87/html5/thumbnails/22.jpg)

All these different types of navigation were made possible by using Topic Maps

Would you still like to be restricted by traditional Web Content Management systems?
![Page 44: Topic Maps 2008](https://reader035.vdocuments.mx/reader035/viewer/2022062405/557c509ad8b42a11668b4e87/html5/thumbnails/44.jpg)
We need to see portals as layered architecture, where content is independent of both presentation and the underlying technology structures.
![Page 45: Topic Maps 2008](https://reader035.vdocuments.mx/reader035/viewer/2022062405/557c509ad8b42a11668b4e87/html5/thumbnails/45.jpg)
Topic Maps is the obvious solution for what Ted Nelson and his earlier fellows were searching for
Information architects and interaction designers are not restricted by technical limitation
![Page 46: Topic Maps 2008](https://reader035.vdocuments.mx/reader035/viewer/2022062405/557c509ad8b42a11668b4e87/html5/thumbnails/46.jpg)
Topic Maps-driven websites are different
The barriers are now broken
