Oracle's Semantic Technologies Center http://www.oracle.com/technology/tech/semantic_technologies/index.html is based on Oracle Spatial 11g and contains links to Oracle's Semantic Technologies and documentation such as Oracle Semantic Technologies Inference Best Practices with RDFS/OWL.

Using Oracle Spatial 11g RDF triples are persisted, indexed and queried, similar to other object-relational data types.

Application areas include:

* Life Sciences: Biological pathway analysis, discovery and enhanced search.
* Defense & Intelligence: Data and content integration, reasoning and inference.
* Enterprise Application Integration: Data and systems integration, semantic enterprise integration and semantic web services.
* CRM/ERP: Supply chain integration, sourcing optimization and customer service automation.
