OWLIM is a high-performance semantic repository, wrapped as a Storage and
Inference Layer (SAIL) for the Sesame (http://www.openrdf.org) RDF database.
OWLIM uses Ontotext's IRRE (Inductive Reasoning Rule Engine) to perform OWL
DLP reasoning, based on forward-chaining of entailment rules. The reasoning
and query evaluation are performed in-memory. In the same time, a reliable
persistence strategy assures data preservation, consistency and integrity.
OWLIM is proven to scale up to tens of millions of statements, maintaining
upload speed of tens of thousands of statement/sec. It can manage millions
of statements even on commodity desktop hardware. OWLIM completes the
LUBM(50,0) benchmark (see http://swat.cse.lehigh.edu/projects/lubm/) within
7 minutes on a $1000-worth machine. Based on the limited evaluation
information available, OWLIM is the fastest OWL repository available.
