The onprom is an event log extraction tool suite using ontology-based data access ( OBDA). It is developed under KAOS: knowledge-Aware Operational Support project to support the various phases of the OBDA-based event log extraction framework.

This project consists of the following modules:

• data: common data classes for modules
• umleditor: UML editor for ontology design and OWL 2 QL export
• annoeditor: Annotation editor for annotating ontology with annotations based on different upper ontologies
• obdamapper: OBDA system mapper
• logextractor: Log extraction module using mappings, ontology and annotation queries
• toolkit: stand-alone toolkit, which provides user interface to use all toolchain
• plugin: ProM plugins (currently doesn't work well and not supported)
• ocel: Java implementation for OCEL standard
• example: XES example in conference submission system domain
• demo: OCEL example in ERP domain

We rely on state-of-the-art ontop system for the OBDA. Ontop is a platform to query relational databases as Virtual RDF Graphs using SPARQL. It is fast and packed with features. It implements the query rewriting and unfolding algorithms together with an extensive set of optimization techniques. Please visit ontop page for more information.
