Response Body

May 31, 2026

Summary

conectaton2026.sanjuan.gob.ar has provided an 'OperationDefinition' based on FHIR standards to detect differences between resources. This functionality allows for the generation of a difference (Diff) document between two versions of the same resource or between two different resources.

Details

This page is a reference for the FHIR OperationDefinition published by conectaton2026.sanjuan.gob.ar. The definition provides an operation named 'Diff,' which aims to compare two resources or two versions of a single resource ('Comparte two resources or two versions of a single resource'). Specifically, it allows the detection of differences between two resources by utilizing parameters such as `from` (source), `to` (target), and optionally `fromVersion`, using specified IDs and versions. It also includes a boolean parameter called `includeMeta` to specify whether differences in the metadata element (`meta`) should be included. Since this operation generates the difference shown as an FHIR Patch document, it is extremely useful for scenarios where tracking or comparing data consistency and changes between systems are necessary. This serves as a crucial technical foundation for accurately grasping how data has changed during healthcare information system interoperability.
