From OpenCog

The Open Cognition Framework (OpenCog) provides research scientists and software developers with a common platform to build and share artificial intelligence programs. The OpenCog Framework framework includes:

  • a flexible and highly optimized in-memory database for knowledge representation,
  • a plug-in architecture for cognitive algorithms and a cognitive process scheduler,
  • a built-in LISP-like programming language, and
  • other components to support artificial intelligence research and development.

Free and Open Source Software

OpenCog borrows development philosophies from many FOSS projects, including Linux and Python and will maintain a highly-inclusive approach to contributions, encouraging a liberal variety of new and replacement components and cognitive architectures, while at the same time enforcing principles of code quality and software architecture consistency. OpenCog projects are released under OSI-approved free software licenses, typically AGPL and Apache2.
