GEDCOM TMG has elaborate and detailed support for sources in a database format where a source can be referred to by any other record. In the
GEDCOM database specification, sources can be attached to any number of individuals or multiple families, by attaching to any number of facts for that individual or family. Exporting a TMG database involves duplicating the sources into each place where a given source is used. All of the information is exported, but the structure of each source is lost permanently. An example is when there is a
census or ship's record that lists many members of an extended family. TMG allows each individual's entry to refer to a common source record, which can itself have an elaborate description. GEDCOM also allows every fact in that census or ship record to apply to a single source, it's simply a matter of tagging the facts with that source. This may vary with how TMG handles sources but that's perhaps the fault of TMG not adhering to the standard that was well established prior to the program being produced. ===Non
GEDCOM exports of TMG=== The following options allow for some form of direct transfer of TMG files, possibly limited, apart from GEDCOM. • tmg2gramps Converts TMG 6 datafiles to a
