6.1 Patterns within the IPS Data Set
6.1.1 General
This document describes an abstract data model which is implementation independent.
The IPS Data Set is hierarchical and the nesting organizes the data elements. At the bottom of the hierarchical description in the IPS there are data elements that can be described in a generic fashion that are not use case dependent. Within the IPS Data Set it is easy to identify structures that have a similar pattern. These “patterns may or may not correspond to “well-known” data types (for example coded elements; date-times; person names; addresses). Examples of these primitive value types that reoccur in the IPS Data Set are:
— Identifiers
— Entity Names (people, organizations, products, etc.)
— Date/time elements (or interval of date/time)
— Address details
— Telecom details
Where applicable, the ISO 21090 data types have been used as reference for describing their main characteristics. For example, when the name of a person is provided, that name should be provided as a list of parts such as given name or family name, prefix, suffix; when more than one part is given it should he allowed to distinguish among their usage (e.g. official name; maiden name); more representations should be recorded when the name is not alphabetic; and so on. All these properties are summarized indicating that the Person Name is related to the ISO EN.PN datatype without repeating all of these characteristics.
When an ISO 21090 data type is referred to, it is not assumed that implementations will have direct conformance (see ISO 21090:2011, 5.2) with them. However, derived models, including implementable specifications, should declare how the used patterns will be realized when not self-evident by the used standards (i.e. indirect conformance, see ISO 21090:2011, 5.3).
In order to better show how the patterns defined by this document may be realized by derived models (in this case by an implementable specification), a reference to the HL7 FHIR® datatypes has been also included. The reason of this choice is due to the presence — at the best of our knowledge – of only two standardization activities related to this IPS standard: one based on the CDA R2 standard and one on [IL7 FHIR®. Since the CDA R2 standard uses a modified form of a previous version of the ISO data types it has not been considered useful to add this as reference. The mapping between the ISO datatypes and the HL7® V3 R1.1 is in fact straightforward: e.g. IVL(PQ) is IVL_PQ; ED is ED; and so on. Other reference implementations may be added in the future if new IPS standardization activities using different data types will be realized.
6.1.2 Label Concept
The term ‘Label Concept’ is used to describe data model elements that play the role of container and usually have complex structures, for instance they may contain clinical statements or details of participants. Label Concepts also facilitate recursive definitions. For example, the result of an assessment can be an assessment.ISO 27269 pdf download.
