Conclusion
Our approach allows adapting an RDF graph (in ifcOWL) into diverse alternative, less complex graphs. usable extension of ifcOWL responding to use case
Similar approaches: The ifcWOD extension (Mendes et al. 2015b) private industrial simplification mechanisms. SPARQL CONSTRUCT queries (C. Zhang, 2016)

Future Work
◼ Transform into alternative ontologies: DogOnt (Bonino & Corno 2008) OntoFM (Dibley et al. 2012) sumo ontology (Niknam and Karshenas 2015)
◼ Perform additional benchmarks, in order to highlight eventual advantages of SimpleBIM for SPARQL query simplification
◼ Examine the related query execution time ECPPM 2016 - An Agile Process Modelling Approach for BIM Projects
