There is a large literature concerning rule engines (forward chaining or backward chaining). During the last thirty years there were various proposals such as RETE, TREAT and the derived Gator algorithm. Significantly, RETE was embedded into various expert systems such as Clips and its successor Jess, and Drools including in a number of commercial rule engines and was extended various times including with support for ECA rules. However, none of them is able to directly process DOM Events. The goal of this paper is to present the architecture of a forward chaining Event-Condition-Action (ECA) rule engine capable to handle Document-Object-Model Events. This architecture is instantiated into a JavaScript-based rule engine working with JSON rules.
