<sect3 id="rdfadmviews"><title>Views</title>
<para>Virtuoso uses a SPARQL-based Meta Schema Language to provide RDBMS-to-RDF mapping
functionality (also described as, Linked Data Views of SQL data). The language is an extension of the
SPARQL query language meshed with Virtuoso's SPASQL (SPARQL-inside-SQL) functionality. The
language enables you to declaratively map relational database schema tables, columns, rows,
and foreign key relationships to Classes, Attributes, Relationships, and Instances
(Objects/Entities/Individuals) defined by RDF Schemas or OWL Ontologies. The mapping
process uses a special built-in Virtuoso function to generate IRIs / URIs in "Subject"
or "Object" position of a SPARQL graph pattern, en route to building a set of SQL compiler
rules and optimizations for translating SPARQL queries into SQL on the fly.</para>
