Health informatics - Service architecture - Part 2: Information viewpoint (ISO 12967-2:2009)
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".

Informatique de santé - Architecture de service - Partie 2: Point de vue d'information (ISO 12967-2:2009)
L'ISO 12967-2:2009 spécifie les caractéristiques fondamentales du modèle d'information qu'une couche architecturale spécifique (c'est-à-dire la couche interstitielle) du système d'informations doit mettre en place pour assurer le stockage cohérent et intégré des données d'entreprise communes et supporter les processus métiers fondamentaux de l'organisme de santé, tel que défini dans l'ISO 12967-1.
Le modèle d'information est spécifié sans émettre d'hypothèse (explicite ou implicite) sur les technologies physiques, les outils ou les solutions à adopter dans les différents scénarios cibles. La spécification n'en est pas moins formelle, exhaustive et sans ambiguïté, afin de permettre aux implémenteurs de prévoir une conception efficace du système dans l'environnement technologique spécifique sélectionné pour sa mise en place physique.
La spécification n'a pas pour objet d'être une représentation fixe et exhaustive de toutes les données possibles susceptibles d'être nécessaires aux exigences d'une entreprise de santé. Elle spécifie simplement un ensemble de caractéristiques (en termes d'objets d'informations organisationnelles et individuelles) identifiées comme étant essentielles pour tous les organismes de santé et que le modèle d'information mis en place par la couche interstitielle doit satisfaire.
Zdravstvena informatika - Arhitektura storitve - 2. del: Informacijski vidik (ISO 12967-2:2009)
Ta del ISO 12967 določa temeljne značilnosti informacijskega modela, namenjenega implementaciji z določeno arhitekturno plastjo (tj. vmesna programska oprema) informacijskega sistema za zagotavljanje celostne in integrirane hrambe skupnih podatkov podjetja in za podporo temeljnim poslovnim procesom zdravstvenih organizacij, kot je določeno v ISO 12967-1.
Informacijski model je določen brez kakršne koli eksplicitne ali implicitne predpostavke o fizičnih tehnologijah, orodjih ali rešitvah, privzetih za njegovo fizično implementacijo v različne ciljne scenarije. Kljub temu je specifikacija uradna, celovita in dovolj nedvoumna, da omogoča tistim, ki jo implementirajo, da izpeljejo učinkovit načrt sistema v določenem tehnološkem okolju, ki bo izbran za fizično implementacijo.
Specifikacija ne stremi k predstavitvi fiksne in celotne specifikacije vseh mogočih podatkov, ki so lahko potrebni za katero koli zahtevo katere koli zdravstvene organizacije. Določa samo sklop značilnosti glede na celotno organizacijo in posamične informacijske predmete, določene kot temeljne in skupne vsem zdravstvenim organizacijam, in da temu ustreza informacijski model, implementiran z vmesno programsko opremo.
Ohranjanje skladnosti z določbami tega dela ISO 12967 dopušča fizičnim implementacijam razširitve standardnega informacijskega modela, tako da podpira dodatne in lokalne zahteve. Razširitve vključujejo definicijo dodatnih lastnosti v predmetih standardnega modela in implementacijo popolnoma novih predmetov. Prav tako se ta standard lahko sčasoma razširi v skladu z razvojem primernih standardizacijskih pobud. Specifikacija za razširitev je izvedena v skladu z metodologijo, določeno v ISO 12967-1:2009, točko 7, »metodologija za razširitve«.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 12967-2 was prepared by Technical Committee ISO/TC 215, Health informatics, based on the European
Standard EN 12967-2:2007 with minor editorial amendments.
ISO 12967 consists of the following parts, under the general title Health informatics — Service architecture:

Introduction
This is the second part of ISO 12967, a multi-part standard that provides guidance for the description,
planning and development of new systems as well as for the integration of existing information systems, both
within one enterprise and across different healthcare organizations through an architecture integrating the
common data and business logic into a specific architectural layer (i.e. the middleware), distinct from
individual applications and accessible throughout the whole information system through services, as shown in
Figure 1.
Applications
Scope of the
standard
Middleware of objects

Figure 1 — Scope
The overall architecture is formalized according to ISO/IEC 10746 (all parts) and is therefore structured
through the following three viewpoints.
a) Enterprise viewpoint: specifies a set of fundamental common requirements at enterprise level with
respect to the organizational purposes, scopes and policies that must be supported by the information
and functionality of the middleware. It also provides guidance on how one individual enterprise (e.g. a
regional healthcare authority, a large hospital or any other organization where this model is applicable)
can specify and document additional specific business requirements, with a view to achieving a complete
specification, adequate for the characteristics of that enterprise.
Enterprise viewpoint is specified in ISO 12967-1.
b) Information viewpoint: specifies the fundamental semantics of the information model to be implemented
by the middleware to integrate the common enterprise data and to support the enterprise requirements
formalized in ISO 12967-1. It also provides guidance on how one individual enterprise can extend the
standard model with additional concepts needed to support local requirements in terms of information to
be put in common.
Information viewpoint is specified in this part of ISO 12967.
c) Computational viewpoint: specifies the scope and characteristics of the services that must be provided by
the middleware for allowing access to the common data as well as the execution of the business logic
supporting the enterprise processes identified in the information viewpoint and in ISO 12967-1. It also
provides guidance on how one individual enterprise can specify additional services needed to support
local specific requirements in terms of common business logic to be implemented.
Computational viewpoint is specified in ISO 12967-3.

Information viewpoint
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”.

5 Methodological principles
5.1 Language and notation adopted for the specification of the model (informative)
The objective of the information viewpoint specification is to describe the information relevant for the
enterprise to be handled by the middleware. It consists of a formal information model detailing the semantic
and syntactic aspects of all data to be managed.
The specification is based on an object model, derived from the enterprise viewpoint by properly structuring
and aggregating the information that has been identified as relevant in the specification of the business
processes, tasks and activities.
While the general approach of the ODP standard is also used for ISO 12967-1, the modelling language to be
used is UML, which was not available at the time of the first edition of the ODP standard.
The information viewpoint is concerned with information modelling (i.e. the kinds of information handled by the
system). It focuses on the semantics of information and information processing in the system. The individual
components of a distributed system must share a common understanding of the information they
communicate when they interact, or the system will not behave as expected. Some of these items of
information are handled, in one way or another, by many of the objects in the system. To ensure that the
interpretation of these items is consistent, the information language defines concepts for the specification of
the meaning of information stored within, and manipulated by, an ODP system, independently of the way the
information processing functions themselves are to be implemented.

SIST EN ISO 12967-2:2011
ISO 12967-2:2009(E)
Thus, information held by the ODP system about entities in the real world, including the ODP system itself, is
represented in an information specification in terms of information objects, and their associations and
behaviour. Atomic information objects represent basic information elements. More complex information is
represented as composite information objects, each expressing associations over a set of constituent
information objects.
Some elements visible from the enterprise viewpoint will be visible from the information viewpoint and vice
versa. For example, an activity seen from the enterprise viewpoint may appear in the information viewpoint as
the specification of some processing which causes a state transition of an information entity.
Different notations for information specifications model the properties of information in different ways.
Emphasis may be placed on classification and reclassification of information types, or on the states and
behaviour of information objects. In some specification languages, atomic information objects are represented
as values. The approach to be taken will depend on the modelling technique and notation being used.
Assessment of conformance to the information specification of a system involves relating the requirements
expressed in the specification to sets of observations of the behaviour of the system at conformance points
identified in the engineering and technology specification, and assessing the degree of consistency between
the requirements and the observations.
5.2 UML Class Diagram notation guidelines and profile (informative)
For each cluster of objects identified in the enterprise viewpoint, the information objects will be illustrated
according to the following rationale.
⎯ Information objects (i.e. classes) grouped in the packages will be not be coloured.
⎯ Classes not expressly grouped in the package will also be represented if there are associations from
classes belonging to the package to these classes. These classes, however, will be coloured in yellow.
⎯ The names of classes will be meaningful and start with a capital letter (e.g. Person). If the name is
composed of more than one word the blank spaces between the words present in the diagrams will be
instead omitted in the tables describing the classes (e.g. “Period of care” in the diagram will become
“PeriodOfCare” in the tables, “Subject of care” in the diagram will become “SubjectOfCare”). Blank
spaces are left in the diagrams for readability reasons.
⎯ Associations will be labelled when the label adds value to the diagram.
⎯ Associations may be labelled through a property, or through a verb phrase; in the latter case, an arrow
will be added to the association label to avoid ambiguity.
⎯ Labels are always in lower case and, if a label is a verb phrase (with arrow), it will have one blank space
in between words.
⎯ Navigability is not relevant when using UML for an information specification and will not be represented.
⎯ In general, for readability reasons, the classes should only contain the name of the class. Properties
should be described in the tables; however, if properties are displayed in the diagrams, the following
holds.
⎯ Notation for visibility of properties is not used, as it is not pertinent for the conceptual models used in
the information viewpoint. Although visibility symbols could be used to indicate access control, this is
not done as all healthcare-related information should be accessed through careful authorization.
⎯ Data types of the properties should be displayed in the class in the diagram.
⎯ For some classes, associations to other classes could be modelled (in the UML diagrams) as attributes to
the class. This reflects that the association has value rather than reference semantics, in addition to the
resulting simplification of the model. In other cases, the same method might be used in the UML diagrams
even though the association has reference semantics. This is done just to simplify the models. In the
related class descriptions, these instances of simplified modelling are described as associations rather
than attributes.
