Graph representations and methods for querying, examination, and analysis of IFC data

This paper presents an approach to apply graph-based methods to IFC data. We discuss (1) the representation of object-oriented data and schemas as graphs including IFC-specific issues, (2) the specification of IFC queries as subgraph templates including their conversion to Model View Definition (MVD) fragments, BIMserver and Cypher queries, (3) graph grammars for IFC model transformation, and (4) visualization schemas for the different graph structures. These fundamentals provide the basis for future work in graph-based model transformation.
