[Tdwg-tag] rdf stores and SPARQL

["Döring, Markus"]

Hello TAG,

I believe scalability and performance in RDF stores IS a major problem and I think we should try to gather as much information about it as possible. Roger, could we start to collect resources in the TAG wiki about it? 
So far I am aware of the following +/- recent articles:

 * http://crschmidt.net/blog/archives/90/rdf-as-backing-storage/ 
 * http://simile.mit.edu/reports/stores/
 * http://km.aifb.uni-karlsruhe.de/ws/psss03/proceedings/harris-et-al.pdf
 * other interesting papers from the same conference "Practical and Scalable Semantic Systems Service": http://km.aifb.uni-karlsruhe.de/ws/psss03/proceedings
 * http://eprints.ecs.soton.ac.uk/11985/01/owens-semanticStorageOverview-ecs.pdf
 * http://www.w3.org/2001/sw/Europe/reports/rdf_scalable_storage_report/

Most of them are sceptical about having large scale rdf stores in the intermediate future and usually suggest to go with a specialised stores for specific appllication purposes. Especially the combination of storing large amounts of data based on complex ontologies with good inference/reasoning/querying support seems unreasonable in a generic solution.

But maybe Oracle can do much better. Has anyone heard claims about their performance yet?
