Wandora's GEDCOM (GEnealogical Data COMmunication) extractor converts GEDCOM files to topic maps format. GEDCOM file format is used to model family relations such as child-parent and wife-husband. The extractor starts with menu option File > Extract > Other > GEDCOM extractor. Wandora's GEDCOM to Topic Maps conversion is not perfect i.e. Wandora doesn't support all GEDCOM features. We have enclosed Wandora samples folder a Topic Maps conversion of European Royals GEDCOM composed by Denis R. Reid. File is also available in Topic map gallery.
