Several years ago a first effort wat made to create a standardized API for online BIM tools and services. This was done onder the flag of BuildingSMART alliance and called BIMSie.

The initiative resulted in a very documented and extensive API.

Now, after a period of usage of the API the need for a more simplified version rises.

While the BIMSie API was published as SOAP and/or JSON, the focus of the webservices seems to shift towards JSON.  The standard received the interest from developers that weren’t used to work under the wings of BuildingSMART and therefor the new initiative is now hosted on

The new API standard is dubbed bimJSON.

The goal of the new bimJSON standard is to support automation between BIM data and online simulation and validation tools. In a way we try to provide the standard for the BIM Bots initiative.
