Health informatics - Terminological resources - Part 1: Characteristics
This document defines universal and specialized characteristics of health terminological resources that make them fit for the purposes required of various applications. It covers only terminological resources that are primarily designed to be used for clinical concept representation or to those parts of other terminological resources designed to be used for clinical concept representation. This document helps users to assess whether a terminology has the characteristics or provides the functions that will support their specified requirements. In order to do that, this document focuses on defining characteristics and functions of terminological resources in healthcare that can be used to identify different types of terminological resources for categorization purposes. NOTE 1 Categorization of healthcare terminological systems according to the name of the system might not be helpful and has caused confusion in the past. The following aspects are not covered in this document: — evaluations of terminological resources; — health service requirements for terminological resources and evaluation criteria based on the characteristics and functions; — the nature and quality of mappings between different terminologies; NOTE 2 It is unlikely that a single terminology will meet all the terminology requirements of a healthcare organization: some terminology providers produce mappings to administrative or classification systems such as the International Classification of Diseases (ICD). The presence of such maps would be a consideration in the evaluation of the terminology. — the nature and quality of mappings between different versions of the same terminology; NOTE 3 To support data migration and historical retrieval, terminology providers can provide maps between versions of their terminology. The presence of such maps would be a consideration in the evaluation of the terminology. — terminology server requirements and techniques and tools for terminology developers; — characteristics for computational biology terminology.

About This Item
TS EN ISO 17117-1 is a standard about the defining characteristics of terminological resources used to represent clinical concepts in health informatics. Its purpose is to help users judge whether a terminology or terminology resource is suitable for a given application by describing the kinds of characteristics and functions such resources may provide. In practice, that shifts the discussion from naming alone to the way concepts are organised, accessed, and made usable in clinical and information-management settings.
How terminological resources are understood in healthcare
In general technical terms, a terminological resource is more than a list of terms: it is a structured resource that organises concepts, terms, definitions, and the relationships between them. In healthcare, such resources support consistent representation of clinical meaning, interoperability, and safer interpretation across systems and workflows. This standard focuses on those characteristics and functions that can be used to categorise different types of terminological resources and to understand what kind of use they are intended to support.
What this part includes, and what it deliberately excludes
The document covers terminological resources primarily designed for clinical concept representation, as well as those parts of other terminological resources that serve that purpose. It does not cover evaluations of terminological resources, healthcare service requirements and evaluation criteria based on characteristics and functions, the nature or quality of mappings between different terminologies, mappings between different versions of the same terminology, terminology server requirements, tools and techniques for terminology developers, or characteristics for computational biology terminology. In general practice, one terminology may not satisfy every organisational need, so mappings can matter in evaluation; however, this standard itself is not a methodology for judging mapping quality.
