(*** We apologize if you receive multiple copies of this announcement ***) Ontotext is happy to announce ver. 2.8 of its OWLIM semantic repository, http://www.ontotext.com/owlim/ 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.
