1 Scope
This part of ISO 12967 specifies the fundamental characteristics of the information model to be implemented
by a specific architectural layer (i.e. the middleware) 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 without any explicit or implicit assumption on
the physical technologies, tools or solutions to be adopted 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 specification 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 middleware.
Preserving consistency with the provisions of this part of ISO 12967, physical implementations allow 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 standard 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 12967‑1:2009, Clause 7, “Methodology for extensions”.
