The present Node.js scripting tool generates a set of rules for a home-grown tiny Expert System. Its Knowledge Base system is built from a number of markdown files (actually, it's Obsidian markdown file format).
The said Knowledge Base JSON files implement (almost
like an inception engine 😁) JsonLogic,
having specific syntax for both facts.json and rules.json.
The actual usage of this rule engine may be seen on MLEX.systems. Please, keep in mind this automatically generated rule set, which, on the outside, looks like live search facility; however, its logic is really extendable.
