It performs semibackward chaining and it supports Euler paths. Via N3 it is interoperable with Cwm. . Semibackward chaining is backward chaining for rules using <= in N3 and forward chaining for rules using => in N3. This can be seen in EYE Reasoning. . Euler paths are roughly "don't step in your own steps" which is inspired by what Leonhard Euler discovered in 1736 for the Königsberg Bridge Problem. EYE sees the rule P => C as P & NOT(C) => C. . Notation3 (N3) is a shorthand non-XML serialization of Resource Description Framework (RDF) models, designed with human-readability in mind: N3 is much more compact and readable than XML RDF notation. . Resource Description Framework (RDF) is a standard model for data interchange on the Web.
