RDF Mapping API

Functions to describe entities and bundles in RDF.

The RDF module introduces RDF and RDFa to Drupal. RDF is a W3C standard to describe structured data. RDF can be serialized as RDFa in XHTML attributes to augment visual data with machine-readable hints.

Modules can provide mappings of their bundles' data and metadata to RDF classes and properties. This module takes care of injecting these mappings into variables available to theme functions and templates. All Drupal core themes are coded to be RDFa compatible.
