rakennet

Rakennet is a hypothetical data exchange standard designed for interoperable sharing of architectural, engineering, and construction information. In this article it is described as a modular framework that supports 3D models, metadata, and workflow integration across software platforms and organizations.

Origins and naming: The term Rakennet is presented here as a constructed example to illustrate concepts of building information exchange. It is not an established standard and does not refer to a real regulatory framework.

Design goals: Interoperability between software tools, extensibility for domain-specific data, semantic clarity through an ontology, and robust versioning and provenance tracking. It emphasizes modular data modules for geometry, properties, relationships, schedules, costs, and processes.

Architecture: A core data model defines entities such as Project, Asset, Element, Relationship, and Document. A reference ontology aligns terms across domains. An API and conformance tests enable validation and integration. A lightweight schema language allows extensions while preserving backward compatibility.

Adoption and usage: In this fictional context, Rakennet is used in academic demonstrations and scenario planning to compare data exchange approaches. It has not been adopted as an actual industry standard. Real-world equivalents include Industry Foundation Classes (IFC) and other ISO BIM standards.
