What if it's useful to LABEL the edges between nodes. And thus/then have multiple edges.

For instance, Strzok has multiple connections to the same person (ie Page etc) but each connection has a different flavor (ie co-conspirator, "textual" relationship). This is my personal gripe with https://DiscoverTheNetworks.org, that it doesn't provide a 10k foot view of how the quid pro quo work. Another example: WJC gives a "speech" on a date, Russia "pays" him for it, and then somehow uranium is exported to them.

Yes, populating this thing will be time-consuming, but we need not try to enter all the details all at once. Eat an elephant one bite at a time.

SSB looks like a winner.

GunDB is very interesting but doesn't have property lists for edges. It's possible to use intermediate nodes for edges, but then the challenge is data management or graph visualization.
