Proposed updated schemas

proposed obXML v1.3.4 documentation

proposed gbXML v7.04 documentation

Proof of Concept - Revit source model

Revit 2024 file

Proof of Concept - gbXML

gbXML file - This gbXML file was generated from Revit and then manually edited to include the proposed OBM elements

Proof of Concept - obFMU

This directory contains the necessary files used to process the data through the obFMU

Proof of Concept - IFC

POC obXML Data Dictionary on the buildingSMART Data Dictionary (bSDD) service - This is not a full schema data dictionary, but only includes mapping of Building, Space, Occupant, Window, and Thermostat to IFC4.3 along with a few sets of custom properties related to OBM requirements for these object classes
