Publishing authoritative geospatial data to support interlinking of building information models

Building Information Modelling (BIM) is a key enabler to support integration of building data within the buildings life cycle (BLC) and an important aspect wide range use cases, related intelligent automation, navigation, energy efficiency, sustainability so forth. Open faces several challenges standardization, interdependency, access, security. In addition these technical challenges, there remains barrier among BIM developers who wish protect their intellectual property, as full 3D development requires expertise effort. This means that often limited availability data. However, Linked Data approach BIM, combined with supporting national geospatial identifier infrastructure makes interlinking controlled sharing models possible. Ireland, Ordnance Survey Ireland (OSi) maintains substantial set, called Prime2, which includes not only GIS (polygon footprint, geodetic coordinate), but also additional specific (e.g. form, function status). The set change information, recording when changes took place captured validated those changes. paper presents based on OSi ontology supports capturing using Resource Description Framework (RDF). details different steps required generate publish First, initial analysis discussed. identification mappings existing standards, e.g. GeoSPARQL handle geometries PROV-O provenance, R2RML RDF method for deploying graphs. then made available dependent licensing agreements handled by access control approach. Methods are presented authoritative other standards sets geolocation, followed finally discussion future work.
