BIM: The key metadata components held in file names, that need to be held and managed to support CDE


What is Metadata?

Metadata is about the container controlling its position and status in the process. The metadata is a set of data that gives information about other data. ISO 19650 series requires, as a minimum, the following metadata within the Common Data Environment (CDE).

Every container should document a single building zone or asset (location), contained within a single volume of space

What is CDE?

A common data environment (CDE) is a digital information platform that centralizes project data storage and access, typically related to construction projects and building information modeling (BIM) workflows. The data stored in a CDE originally consisted of BIM data and information.
