Two incarnations, one project

The project has had two implementations, twenty years apart, and each has its own pages here. They are not two versions of one codebase: 2P-Kt is a reboot, written afresh in a different language, on a different architecture, under a different licence.

implementation	what it is	since	licence
tuProlog	the light-weight Java engine, later ported to .NET, Android and iOS — unmaintained	2001	LGPL
2P-Kt	the multi-platform Kotlin ecosystem for symbolic AI — current	2020	Apache 2.0


tuProlog	2P-Kt

Where to look

Publications, talks and theses are listed on both sets of pages, each under its own tag; this page keeps the two lists together, as it always has. Everything else — documentation, downloads, sources, licence — is specific to one implementation or the other, and lives with it.
