Emerged finds new products worth a look, daily — what’s new today
If you need to know both when a fact was true and when you learned it, Minigraf gives you that in a library you ship inside your app, with no server.
Minigraf is a dual Apache-2.0 and MIT graph database that lives in one file or in memory, in the spirit of SQLite. You query it with Datalog, including recursive rules, and every fact carries two timelines: when it was recorded and when it held true, so you can ask what the graph looked like at any point. Version 2.0.3 has 1,219 tests and bindings for Python, Node, browser WASM, Java, Android, iOS and C.
