Introduction

A Direct Mapping of Relational Data to RDF defines a simple transformation, providing a basis for defining and comparing more intricate transformations. This document includes an informal and a formal description of the transformation, as well as a number of refinements intended both to meet use cases and establish a pattern for defing extensions.
