City information modeling or CIM is in many ways a natural expansion of the now well-established building information modeling (BIM) that has become a in the UK a prerequisite to many publicly procured projects.

Building-level information used by building information models (BIM) may be standardised by the Industry Foundation Classes (IFC) data model, a neutral and open specification developed by the International Alliance for Interoperability (IAI). This is an object oriented file format with a supporting data model facilitating interoperability in the building industry. Industry Foundation Classes (IFC) is covered by ISO 16739-1:2018: Industry Foundation Classes (IFC) for data sharing in the construction and facility management industries — Part 1: Data schema. In practical and scaled terms its use extends from products level information to the level of the building or cluster of buildings on a site.

City information modeling (CIM) extends beyond this from the building level up to the city and beyond, even to the global scale. City information modelling uses a spatial data exchange
