Introduction COINS 2.0 (April 2016)

The COINS standard provides an information model and exchange format by means of a container for BIM related data.


The standard is an answer to the increasing need to describe and enable the information deliveries (data drops) between actors in the construction process.  This standard supports the situation in practice that these data drops are a combination of data sets according to multiple formats en differing standards, as well as proprietary formats. Available BIM standards are not equipped to support this practical situation.


The importance of this standard is the integration of open data based on differing standards (as well as proprietary formats, where needed), but packaged up in a way that makes explicit links between multiple representations of the same object. For example, a construction component such as a road abutment may be defined in a BIM library (as a type), linked to text specification or meta data, and include a 3D representation in a IFC file and/or a 2D representation in a GIS file.


Its main characteristics are summarized:


COINS 1.0 was released in 2010. A first minor update COINS 1.1 was released in 2014. Documentation of those releases can be found by following this link:


COINS 2.0 is a major update. In this edition the core model is even smaller and it makes more use of OWL features. The development of COINS 2.0 is finalized in January 2016. Final documentation is expected May 2016. 


Materials are now available to give a good idea of the specification of 2.0 COINS. This can be found in:
