Обсуждение: Connect RDF to PostgreSQL?
I am presenting on PostgreSQL tonight and someone e-mailed me with a question before my talk so I might be able to find him an answer: "We are starting a new, large project that uses an ontology based ( RDF - Resource Description Framework http://en.wikipedia.org/wiki/Resource_Description_Framework ) approach to organize data, which provides a lot of flexibility. The only viable database we have found that supports this is Oracle, who have tightly integrated their database interface to efficiently support sparql ( http://en.wikipedia.org/wiki/SPARQL ) queries. Other databases seem to only interface to the open source jena technology, which fails to scale to larger data sets as it tries to read huge chunks of data into memory. We would prefer to go with an open source option, but can't. Do you know of a software package that can efficiently connect RDF to PostgreSQL?" Aaron Thul http://www.chasingnuts.com

If you want to support RDF as storage we do have native xml capabilities. http://www.postgresql.org/docs/8.4/static/datatype-xml.html Sincerely, Joshua D.
