In the context of Topic Maps I have used traits to extend the behaviour of the base class TM. One typical example would be TM::Graph which extends the basic behaviour of the base class by interpreting a topic map as a graph. Another example is TM::Tree which adds functionality to project trees into a topic map (typical pedigree stuff), and also TM::Bulk adds more methods.

As a former information scientist, I am fascinated since 1999 by the capabilities for building Topic Maps-based knowledge systems having the potential to augment human mind. One can model arbitrary knowledge organization systems, deal with semantic heterogeneity, collocate all facts about one subject in one logical place, and with TMQL have semantic retrieval on federated semantic networks. Therefore I expect bright prospects for business concepts building on the exchange of such knowledge snippets via semantic knowledge services.
