OWLIM-Lite Fact Sheet - OWLIM42 - Ontotext Wiki. OWLIM-Lite is a high-performance semantic repository created by Ontotext including a native RDF rule entailment engine. It is implemented in Java and packaged as a Storage and Inference Layer (SAIL) for the Sesame openRDF framework. The supported semantics can be configured through rule-set definition and selection. Rule-sets for OWL-Horst [21], unconstrained RDFS [7] with OWL Lite [10] and the OWL2 RL profile [25][26] are included. Custom rule-sets allow tuning for optimal performance and expressivity. Reasoning and query evaluation are performed in-memory. A reliable persistence strategy ensures data preservation, consistency, and integrity. The key features of the current release of OWLIM-Lite can be summarised as follows: OWLIM-Lite is a Java library without user interface.
