Transcript of Topic Maps 2008
Topic Maps-driven Websites are Different
Ted Nelson: Web sites are seen as decorated directories.
Our everyday challenge: Build the ideal, hypertext based knowledge portal
Existing technology has failed to meet expectations regarding the original ideas of hypertext
Obtain new tools that render possible new solutions
Topic Maps may be the tool for building these web sites
Web sites became copies of technical structures
Most of these structures are hierarchical
To avoid these shortcomings, someone invented the concept of portlets.
Portlets made it possible to place related information beside each other
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
Portlets works fine for stock brokers
How is knowledge natively organized?
Nobody knows
Knowledge is not natively hierarchical
Building hierarchies are skills you learn at school.
Knowledge is generally understood as concepts associated with each other
The same way Topic Maps are built
To avoid the shortcomings, content must be separated from presentation
from here

Presentation is a visual aid to support the understanding of information
Only separation of content and presentation makes innovation possible
It should be possible to make different perspectives into the same information..
.. and see the information from different angles
Examples of how to make the most out of Topic Maps
Postens intranett

Made hierarchical navigation available

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?
We need to see portals as layered architecture, where content is independent of both presentation and the underlying technology structures.
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
Topic Maps-driven websites are different
The barriers are now broken
