What do we mean when we talk about information modeling?
We often discuss information models and the standardisation of information modelling and BIM. But what do we mean by these terms? The concepts are broad, and the same term is used to refer to very different things.
buildingSMART Finland desribes an information model in the built environment as:
- The physical objects and characteristics of the built and buildable environment.
- The information that transfers throughout its lifecycle, from planning to construction and maintenance of the finished product.
An information model maintains and moves the data content of physical objects, enabling specific data to be extracted from vast information for particular purposes. The information model is a formal definition of data – it outlines the information and the relationships between them.
Information modelling refers to the representation of objects in the built environment using computer applications, describing object data, and transferring information in a format interpretable by computer applications.
In the standardisation of information modelling, the content is transformed into a regular and machine-readable format. Standardisation creates practices that genuinely enable workflow based on information models.
In the standardisation of information modelling, the following activities are undertaken:
- National information modelling requirements are established, defining how information models are used throughout the lifecycle of the built environment.
- Definition of data content: determining what information is moved within the built environment.
