The Topic Maps Application Programming Interface (TMAPI) provides a standardized way for working with Topic Maps, but only in Java. TMAPI implementations in other programming languages use a different stack – not harnessing the existing Java code. In this paper we describe a different approach, reusing Java TMAPI implementations to build a high level Topic Maps API for the Ruby programming language without a heavy wrapper layer around the Java Objects.

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.
