[Haskell-cafe] What is your favourite graph library?

[Jeffrey Brown]

I wrote Hode[1], a library for a generalization of graphs. Relatiionships
in Hode can have any number of members, and those members can themselves be
relationships. Relationships are "templated"; relationship templates are
the natural generalization of edge labels. Hode includes a TUI and a query
language resembling natural language.

I intended it to be for managing a personal knowledge base. Hode is more
expressive than anything I know about, but (so far) harder to use. Encoding
things is easy, and search is as easy as I think can be hoped for -- but
deciding *how* to encode things turns out to be really hard. So much so
that I've ended up using Semantic Synchrony[2] and org-roam[3] instead.
