SIST EN ISO 13606-2:2019

Overview

SIST EN ISO 13606-2:2019 - Health informatics: Archetype interchange specification defines how archetypes (formal clinical data models) are represented and exchanged to support interoperable Electronic Health Record (EHR) communication. Part 2 of the ISO 13606 series specifies an Archetype Model and an optional serialized representation for communicating single or multiple archetypes between repositories, archetype services, EHR systems and middleware components. The standard is intended primarily for direct care and population monitoring (e.g., registries, public health), while secondary uses (research, audit) may still benefit when anonymization/aggregation is applied.

Key technical topics and requirements

• Archetype representation requirements - metadata, publication and governance information, node and data-value constraints.
• Archetype object model (AOM) - structured package definitions including identification, top-level metadata, structural definitions and validity rules.
• Constraint model and primitive constrainers - mechanisms to express constraints on clinical data values and structures.
• Rules package - invariant/rule specifications (renamed from “invariants”) for validation logic.
• Terminology package - term bindings, value-sets and external terminology integration (expressed as URIs following IHTSDO format).
• Templates - treated within the archetype construct (a template is an archetype).
• Conformance - requirements for implementations exchanging archetypes and using the optional serialized format.
• Optional serialized exchange format - recommended for archetype libraries, validation services or persistence layers.

Notable updates in the 2019 edition include introduction of an internal coding scheme (id-codes, at-codes, ac-codes), multi-part namespace identifiers, explicit value-sets, full specialisation support, tuple constraints for co-varying attributes, re-engineered primitive constrainers, node-level annotations and restructured terminology sections.

Practical applications and who uses this standard

• EHR vendors and system integrators - to exchange, validate and persist shared clinical models across systems.
• Clinical application and middleware developers - to enable decision support, validation and data mapping using interoperable archetypes.
• Archetype/library service providers - for archetype repository synchronization and distribution.
• Health informatics architects and implementers - to design federated or centralized EHR solutions that preserve semantic interoperability.
• Registry and public health teams - to standardize data capture for population monitoring and surveillance.

Related standards and context

• Part of the ISO 13606 series (multi-part EHR communication standard).
• Works alongside clinical terminologies and messaging standards to achieve semantic interoperability and reliable structured clinical data exchange.
