Conclusion

Java developers will find the interface simple enough to be used right away, as was the case for our project. TMAPI covers the building of Topic Map structures in memory and offers also means to navigate through such a structure in a standardized way.

Other features like transaction management, application-controlled merging (when and how) or persistency issues (how and where is a topic map stored) are outside the TMAPI scope and have to be dealt with particular implementations. Also not part of TMAPI (yet) is a high-level query language. This may change once TMQL is out.
