I am enthused by Topic Maps since my first encounter back in 1999. That’s no surprise for an information scientist interested in augmenting human knowledge processes by information systems in computers. The paradigm of subject-centricity helps collocating all facts about a subject in one logical place, bridging all kinds of media, syntactic and semantic gaps – ideal for knowledge integration! Knowledge organization systems such as lightweight ontologies, thesauri or faceted classification systems can be easily modelled by and for humans, and also processed by computers. Semantic retrieval comes true with TMQL. Because no particular world view is imposed, semantic heterogeneity can be flexibly dealt with. This opens up fascinating prospects for knowledge federation and knowledge gardening, and new products and services based on the exchange of semantic network fragments via semantic knowledge services in the socio-semantic web.

Topic Maps offered the semantic flexibility that I needed in Topincs, an application with an unlimited domain. It allowed me to make statements about any subjects. Exactly what I was looking for.
