Comparison of versioning methods to improve the information flow in the planning and building processes

• Version management is a prerequisite for digital information flow between phases in the planning and building processes. Information evolves over time and many parties retrieve information from the various phases. The aim of this article is to evaluate versioning methods, focusing on geodata buildings in the 3D cadastre process. The main attention in the evaluation is on the comprehensive ISO standard Product Lifecycle Support (PLCS). PLCS is evaluated against two simpler versioning methods, the versioning in CityGML 3.0 and a modified Git versioning method implemented in CityJSON. CityGML 3.0 fulfils all but one requirement and PLCS meets all. The methods vary in complexity; the Git proposal is a simple solution, easy to implement and maintain, while PLCS includes all functionalities and is complex to implement. There is a trade‐off between number of functionalities and complexity, it is therefore important that the intended purpose determines the choice of versioning method.
