This part of ISO22600 introduces the underlying paradigm of formal high-level models for architectural components. It is based on ISO/IEC10746 (all parts) and introduces the domain model, the document model, the policy model, the role model, the authorization model, the delegation model, the control model, and the access control model.

The specifications are provided using the meta-languages Unified Modelling Language (UML) and Extensible Markup Language (XML). Additional diagrams are used for explaining the principles. The attributes used have been referenced to the HL7 reference information model (see ISO21731:2006) and the HL7 data type definitions.

The role model has been roughly introduced referring to ISO21298.
