The Cybernetics Oriented Interpreter (CYBOI) is the active core system that serves as interface between the computer hardware and the passive knowledge encoded in CYBOL. It is placed under the GNU General Public License (GPL) so that it will always be free, and any extensions to it will be free as well.



The XML- or JSON-based Cybernetics Oriented Language (CYBOL) is used to model abstract knowledge. The CYBOL core models are put under the GNU Lesser General Public License (LGPL), so that not only free software developers (knowledge modellers) can make use of them, but also commercial companies. The reason is that companies use algorithms, workflows, concepts, organisational knowledge and data in general, which they want to keep private. An insurance company, for instance, uses special algorithms to calculate their policies; healthcare institutions use their own organisational concepts.


An external open source project is developing a CYBOL editor called CYBOLE.
