# Service request model - EHDS Logical Information Models v0.3.0 * [**Table of Contents**](toc.md) * [**Artifacts Summary**](artifacts.md) * **Service request model** ## Logical Model: Service request model | | | | :--- | :--- | | *Official URL*:http://www.xt-ehr.eu/fhir/models/StructureDefinition/EHDSServiceRequest | *Version*:0.3.0 | | Draft as of 2026-02-06 | *Computable Name*:EHDSServiceRequest | The model covers details about a requested service or services. One order may include several requests. **Usages:** * Use this Logical Model: [Encounter model](StructureDefinition-EHDSEncounter.md), [Imaging report model](StructureDefinition-EHDSImagingReport.md), [Imaging study model](StructureDefinition-EHDSImagingStudy.md), [Laboratory report model](StructureDefinition-EHDSLaboratoryReport.md)...
