The Digital Buildings project is an open-source, Apache-licensed effort to create a uniform schema and toolset for representing structured information about buildings and building-installed equipment. A version of the Digital Buildings ontology and toolset is currently being used by Google to manage buildings in its portfolio.
The Digital Buildings project originated from the need to manage a very large, heterogeneous building portfolio in a scalable way. The project aims to enable management applications/analyses that are trivially portable between buildings. This goal is achieved through a combination of semantically-expressive abstract modeling, an easy-to-use configuration language, and robust validation tooling. Digital Buildings work has been inspired by Project Haystack and BrickSchema, and maintains cross-compatibility and/or convergence as a long-term objective.
In creating the Digital Buildings project, we have considered the following:
- Human Readability
- Machine readability and interpretation
- Composable functionality
- Dimensional Analysis
- Correctness validation
- Cross compatibility
This project is structured as following:
- An ontology that defines the parameters of the semantic data model and tools for building, validating and associating real equipment with a specific model. It contains the following formats:
- Tools which allow the following:
- Yaml Validator which allows to validate the yaml ontology upon a change or an extension.
- RDF/OWL Generator which allows to generate an RDF version from the yaml ontology files.
- Internal Building Representation (IBR) File Format to represent data from different verticals such as spatial, assets.
