This part of ISO/IEC 16500 describes an Abstract System Reference Model (ASRM) at the highest level first and
then creates a specific instance of this abstract model to define the DAVIC System Reference Model (DSRM).
The ASRM and DSRM are not intended to indicate preferred implementations of the DAVIC System; but are to
be used as a tool to guide the definition of DAVIC specifications. Additionally, as DAVIC specifications are
issued, the reference models can be used to aid the development and implementation of DAVIC-compliant
systems and products.
