The new W3C standard RDF (Resource Description Framework) describes a metadata infrastructure which can accommodate classification elements from different vocabularies i.e. schemas. The underlying model consists of a labeled directed acyclic graph which can be linearized into eXtensible Markup Language (XML) transfer syntax for interchange between applications.This paper will demonstrate how a new system, Metalog, allows users to write metadata, inference rules and queries in English-like syntax. We will demonstrate how these reasoning rules have equivalent representation both as RDF descri
