Openness
in relation to data and information – also linked to interoperability means that it is provided or made available in a format that can be accessed and used withoutrecourse to the software that generated it. Openness is the opposite of proprietary, whereinformation and data are in the generating software’s native format and may or may […]
open interoperability
the meaning and benefits: single procurement of information that can be relied upon over time, removing the need for it to be repeatedly re-procured; a ‘Golden Thread’ of information to provide statutory information in order to improve compliance, health and safety and zerocarbon targets; faster, more efficient and reliable decision making using reliable information; efficient […]
Model View Definition (MVD)
One or more specific information exchange requirements may necessitate the need for a model view definition (MVD). A machine-readable representation of MVDs is required when using them in software development. Filtering information in software tools can be done by using an MVD that is only dedicated to one information delivery model (IDM). An MVD can […]

BIM collaboration format (BCF)
BIM Collaboration Format (BCF) is an open file format that allows the addition of textual comments, screenshots, and other information on top of the IFC model layer for improved communication among coordinating parties. It decouples communication from the model itself.
