I don’t completely understand the error, but looks like some methods from Base might need to be exended.
What is the minimum I would need to implement to make this work?:
g1 = MetaDiGraph(4)
add_edge!(g1, 1, 2)
add_edge!(g1, 2, 3)
add_edge!(g1, 3, 4)
set_props!(g1, 1, Dict(:name=>"A", :id => 1))
set_props!(g1, 2, Dict(:name=>"B", :id => 2))
set_props!(g1, 3, Dict(:name=>"C", :id => 3))
set_props!(g1, 4, Dict(:name=>"D", :id => 4))
g2 = MetaDiGraph(2)
add_edge!(g2, 1, 2)
set_props!(g2, 1, Dict(:name=>"E", :id => 5))
set_props!(g2, 2, Dict(:name=>"F", :id => 6))
h = union(g1, g2) # something like
get_props!(h,1) == Dict(:name=>"A", :id => 1)
get_props!(h,2) == Dict(:name=>"B", :id => 2)
get_props!(h,3) == Dict(:name=>"C", :id => 3)
get_props!(h,4) == Dict(:name=>"D", :id => 4)
get_props!(h,5) == Dict(:name=>"E", :id => 5)
get_props!(h,6) == Dict(:name=>"F", :id => 6)
collect(edges(h)) # something like
Edge 1=>2
Edge 2=>3
Edge 3=>4
Edge 4=>5
Edge 5=>6
