Re: Easy and simple Linux triple-store

I think Redland would be the equivalent of SQLite. I think it's backed by
BerkeleyDB or something. The whole suite comes with lots of useful
command-line tools.

You could also just maintain an in-memory graph, and re-write it to disk on
program exit. Can write modifications to disk as they happen for more
durability, as a write-ahead log.
