Common Reference Model

The design process in complex projects is characterised by a very high frequency of change and with multiple disciplines working in the same areas using the same basic data for referencing. To manage change and concurrency, we need to build a model that can handle both global and local changes and that can hold stable references to all other functional model entities. To support this, a Common Reference Model (CRM) is used.

References to the CRM entities are registered by the referencing elements and can be found by querying the referencing element, that is q backref.
