In fact I do not agree with the assertion that "all implementations are
the same". TM4J, for example exposes the merging of topics as the
aggregation of multiple Topic objects, rather than taking the TMAPI
approach of one Topic object per subject. I am sure that the way in
which TM4J represents scope is different from other implementations too.
What all implementations do have in common is that there are
representations of the topics, topic characteristics, associations and
scope, and it is the semantics of these constructs that the topic map
standard must concern itself with.
