A SPARQL query engine for binary-formatted IFC building models

A prototypical implementation of the query engine is provided in the Python programming language. In several realistic use cases, the proposed system performs equivalent to or better than the state of the art in SPARQL querying on building models. For large datasets, the proposed storage format results in files that are 2-3 times smaller than the current, most concise, RDF databases while offering a platform-neutral, containerized exchange file.
