How to read a GEDCOM file with Julia?

Question

I have a GEDCOM file exported from Ancestral Quest with my family tree, it is quite extense, and I would like to do some analysis on it. I want to construct a tree structure, and explore it recursively.

Is there any library that could read the GEDCOM file and create the tree structure, or some type of directed graph?

Answer 1

You can use python-gendom to parse the file and transform it to a LightGraphs' graph. Subsequently GraphPlot can be used to actually make a plot.

Here is a working code skeleton to start with:

using PyCall
using Conda
using LightGraphs
run(`$(PyCall.python) -m pip install python-gedcom`)
gedcom = pyimport("gedcom")
gparser = pyimport("gedcom.parser")
gedcom_parser = gparser.Parser()
# download from "https://www.gedcom.org/samples/555SAMPLE.GED"
gedcom_parser.parse_file("c:/temp/555SAMPLE.GED")
g = SimpleDiGraph()
for el in gedcom_parser.get_root_child_elements()
    display(el)
    # todo populate graph g
    # recursively iterate over tree
    # see https://pypi.org/project/python-gedcom/ for more details how to read the data
end
# todo use GraphPlot to plot the graph
