cripu: x1 is a bridge/span over/across x2 between x3 and x4 [unordered, typically destination first].
dargu: x1 is a road/highway to x2 from x3 with route x4 (x2/x3 may be unordered).
vorme: x1 is a doorway/gateway/access way between x2 and x3 of structure x4.
I would interpret x2 and x3 same for all of these (as places/points/rooms connected by the structure).
How to describe two-way doors, bridges and streets?
relfarna dargu?
Side note; I searched for "bidirectional" and didn't find anything in vlasisku.
I then had a look for "graph";
There is fancyxra meaning https://en.wikipedia.org/wiki/Graph_of_a_function
But I couldn't find anything for https://en.wikipedia.org/wiki/Graph_(mathematics)
Other graph related words ("edge", "vertex", "node", etc.) also seem to be missing.
Did I fail to find the gismu for these concepts, or is Lojban lacking some basic, important, and useful mathematical concepts?

cripu, dargu have "to"/"from" places but not vorme
klaji doesnt have "from" place.
how would you express them when they are absent? How to describe two-way doors, bridges and streets?
