Oracle Spatial and Graph RDF Semantic Graph Developer's Guide provides usage and reference information about Oracle Database Enterprise Edition support for semantic technologies, including storage, inference, and query capabilities for data and ontologies based on Resource Description Framework (RDF), RDF Schema (RDFS), and Web Ontology Language (OWL). The RDF Semantic Graph feature is licensed with the Oracle Spatial and Graph option to Oracle Database Enterprise Edition, and it requires the Oracle Partitioning option to Oracle Database Enterprise Edition.


You must perform certain actions and meet prerequisites before you can use any types, synonyms, or PL/SQL packages related to RDF Semantic Graph support. These actions and prerequisites are explained in Enabling RDF Semantic Graph Support.


This guide is intended for those who need to use semantic technology to store, manage, and query semantic data in the database.

You should be familiar with at least the main concepts and techniques for the Resource Description Framework (RDF) and the Web Ontology Language (OWL).
