I created a gedcom genealogy type database file of the structure of
the US government. It starts with the voters, then goes to the US
Constitution, Bill of Rights and the three branches of government of
the United States. There are multiple "fathers' and "families" for
many of the nodesthis is to faciltate multiple logical relationships,
for instance to reflect that the President is beholden to the Bill of
Rights and the US voters (but the latter through the Electoral
College).
There are 539 "individuals" or nodes.
It's here:
