Hi,

Further development of the [ClojureProtegeIDE](https://github.com/rururu/ClojureProtegeIDE) project based on the [Protege 3.5](https://protege.stanford.edu/download/protege/3.5/installanywhere/Web_Installers/) ontology editor and rule-based engine of RETE type [rete4frames](https://github.com/rururu/rete4frames)

Home: [https://github.com/rururu/ClojureRulesIDE](https://github.com/rururu/ClojureRulesIDE)

Specila Features:

1. **Representing knowledge as ontologies.** Using an ontology editor Protege 3.5 to represent a subject area (frame data model) in object-orientet form.

2. **RETE algorithm.** Protege 3.5 functionality has been expanded with the implementation of the [RETE](https://en.wikipedia.org/wiki/Rete_algorithm) algorithm for knowledge processing. This is especially useful for Expert system fast prototyping.
