Standards Development
This document provides guidelines for the data exchange between BIM and GIS through metadata. This document explains the role that metadata plays in facilitating data exchange within the framework of the standards referenced in ISO/DIS 23143-1, Clause 6.3 (Metadata resources).
This document offers a perspective on leveraging metadata to ensure interoperability between BIM and GIS. It builds on the core principles established in ISO/DIS 23143-1 by presenting how metadata supports communication between the two domains, thereby facilitating seamless data exchange
This document defines a framework for facilitating data exchange between Building Information Modelling (BIM) and Geographic Information Systems (GIS) through metadata-driven interoperability. It specifies methods for identifying and cross-mapping metadata elements in the GIS Metadata Schema (ISO 19115-1:2014), and for deriving BIM-side metadata from IDM Data Schema (ISO 29481-3:2022) to support semantic alignment and structured transformation between the two domains. ISO 29481-3:2022 is used as a source to derive BIM-side metadata candidates for cross-mapping and is not treated as a metadata schema.
The scope of this part includes:
1) Establishing metadata-based cross-mapping rules to support the semantic translation of information between BIM and GIS, including the use of BIM-side metadata candidates (derived from ISO 29481-3:2022) and GIS metadata elements (ISO 19115-1:2014);
2) Supporting bidirectional information requests and responses, where each domain (BIM or GIS) can serve as either information provider or consumer.
