Sharing building information over the Web is becoming more popular, leading to advances in describing building models in a Semantic Web context. However, those descriptions lack unified approaches for linking geometry descriptions to building elements, derived properties and derived other geometry descriptions. To bridge this gap, we analyse the basic characteristics of geometric dependencies and propose the Ontology for Managing Geometry (OMG) based on this analysis. In this paper, we present our results and show how the OMG provides means to link geometric and non-geometric data in meaningful ways.Thus, exchanging building data, including geometry, on the Web becomes more efficient. ispartof: pages:304-313 ispartof: Proceedings of the 2019 European Conference for Computing in Construction pages:304-313 ispartof: 2019 European Conference on Computing in Construction (2019 EC3) location:Chania, Greece date:10 Jul - 12 Jul 2019 status: Published online |
