|3store from The University of Southampton|
3Store: MySQL based triple store, currently holding over 30 million RDF triples used by a range of Knowledgeable Services developed within the AKT project. Also used by a number of external projects and companies.
What's the Problem?
Many Semantic Web applications require large quantities of RDF triples to perform their reasoning over.
Current RDF database technology only scales to hundreds of thousands or maybe a few million triples, and from our experience in the AKT project we know that many interesting Knowledge Bases can quickly grow to tens of millions of triples before they become truly interesting.
Towards a Solution
3store is a core C library that uses MySQL to store its raw RDF data and caches.
The library offers OKBC and RDQL query interfaces, over HTTP (via an Apache web server module), or directly though the C library.
