The [[DeepaMehta]] Webclient is based on the concept of Topic Maps. Topic Maps is a standard for the representation and interchange of knowledge, with an emphasis on the findability of information. A topic map represents information using:

    * Topics - representing any concept, from people, countries, and organizations to software modules, individual files, and events,
    * Associations - representing hypergraph relationships between topics and
    * Occurrences - representing information resources relevant to a particular topic (like e.g. the location of a topic in a geo-map or relevant associations to other topics).

So the simpliest topic map looks like this:

{{{

         Association
   O ---------------------- O
Topic A                  Topic B

}}}
