Simplified Formats for openEHR Data STABLE

Simplified JSON and XML formats for use with openEHR REST APIs. Provides a more compact, approachable data representation for common EHR data exchange scenarios and integration use cases. The simplified formats reduce nesting depth and remove meta-model artefacts such as explicit type discriminators that are unnecessary for common integration scenarios. They are defined as a subset of the canonical formats, with a normalisation mapping allowing round-trip conversion without data loss for supported data types.

Purpose

This document specifies the Simplified Formats as a JSON representation for openEHR data instances. It provides a simplified, developer-friendly alternative to canonical openEHR JSON and XML serializations by using human-readable field identifiers rather than archetype paths.

These formats are designed to lower the barrier to entry for working with openEHR data by providing a more accessible way to create and manipulate content (e.g. Compositions) compared to the canonical formats, making it easier for developers who are new to openEHR.
