This document specifies the fundamental characteristics of the information model implemented by
a specific architectural layer (i.e. the service architecture) of the information system to provide a
comprehensive and integrated storage of the common enterprise data and to support the fundamental
business processes of the healthcare organization, as defined in ISO 12967-1.
The information model is specified in this document without any explicit or implicit assumption on the
physical technologies, tools or solutions to adopt for its physical implementation in the various target
scenarios. The specification is nevertheless formal, complete and non-ambiguous enough to allow
implementers to derive an efficient design of the system in the specific technological environment that
will be selected for the physical implementation.
This document does not aim at representing a fixed, complete, specification of all possible data that can
be necessary for any requirement of any healthcare enterprise. It specifies only a set of characteristics,
in terms of overall organization and individual information objects, identified as fundamental and
common to all healthcare organizations, and that is satisfied by the information model implemented by
the service architecture.
Preserving consistency with the provisions of this document, physical implementations are allowed
extensions to the standard information model in order to support additional and local requirements.
Extensions include both the definition of additional attributes in the objects of the standard model, and
the implementation of entirely new objects.
Also, this document specification is extensible over time according to the evolution of the applicable
standardization initiatives.
The specification of extensions is carried out according to the methodology defined in ISO 12967-1:2020,
Clause 7.
