From the announcement:
TMAPIX I/O provides readers for nearly all known Topic Maps syntaxes and supports RDF as well. Further it writes TM/XML, XTM 1.0, XTM 2.0, XTM 2.1, LTM 1.3 and JTM 1.0.
TMAPIX I/O is compatible to all Topic Maps engines which implement the TMAPI interfaces.
A few CTM-related “bugs” will be fixed before the official release of TMAPIX I/O 0.4.0 later this year. A bit formal to have official pre-1.0 releases. But, for Lars I will buy the party hats.
