The main problem of such applications is the complexity of the data base modelled with the topic map paradigm. Because of these market requirements of a powerful and meaningful query languages, like TMQL, become more important. TMQL4J is a javabased TMQL engine, which contains different components to support the full process of parsing and interpreting TMQL statements. The engine implements the current draft of TMQL, which is far from the final standard, because of that we have to discuss the benefits and disadvantages of the current draft.

I like the easy but powerful way of merging Topic Maps to extend and combine existing knowledge bases. Thus I see high potential in distributed environments where peer to peer solutions may open the gates to the real Web 3.0.
