Frankly, my dear, I don't give a damn

Mapping Rete algorithm to FOL and then to RDF/N3 "There is already a well established precedent with Python/N3/RDF reasoners (Euler, CWM, and Pychinko). FuXi used to rely on Pychinko, but I decided to write a Rete implementation for N3/RDF from scratch - trying to leverage the host language idioms (hashing, mappings, containers, etc..) as much as possible for areas where it could make a difference in rule evaluation and compilation.

What I have so far is more Rete-based than a pure Rete implementation, but the difference comes mostly from the impedance between the representation components in the original algorithm (which are very influenced by FOL and Knowledge Representation in general) and those in the semantic web technology stack."

The goes on to describe how the mapping from Semantic Web concepts to concepts used in the Rete algorithm (tokens, object type, alpha, beta, and terminal nodes). Some comments, RDF a hole to no where.
