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.

equally
have
something
to
offer.
Why
not
combine
them
and
get
the
best
