DAK API Documentation Hub

DAK API Documentation Hub

This page provides access to Data Access Kit (DAK) API documentation and schemas.

Table of Contents

  1. DAK API Documentation Hub

This page provides access to all available DAK (Data Access Kit) API endpoints and schemas. The DAK API provides structured access to ValueSet enumerations and Logical Model definitions used throughout this implementation guide.

OpenAPI Documentation

Interactive Swagger UI documentation for all generated schemas and external API specifications is available in the OpenAPI documentation hub: View OpenAPI Documentation

Using the DAK API

Schema Validation

Each JSON Schema can be used to validate data structures in your applications. The schemas follow the JSON Schema Draft 2020-12 specification and include:

  • Type definitions and constraints
  • Property descriptions and examples
  • Required field specifications
  • Enumeration values with links to definitions

JSON-LD Semantic Integration

The JSON-LD vocabularies provide semantic web integration for ValueSet enumerations. Each vocabulary includes:

  • Enumeration class definitions with schema.org compatibility
  • Individual code instances with canonical IRIs
  • Property definitions with range constraints
  • FHIR metadata integration (system URIs, ValueSet references)

Integration with FHIR

All schemas are derived from the FHIR definitions in this implementation guide. Each schema page includes links to the corresponding FHIR resource definitions for complete context.

API Endpoints

The enumeration endpoints provide machine-readable lists of all available schemas, making it easy to discover and integrate with the available data structures programmatically.

Logical Models

The following logical models define the structure for computable representations of WHO DAK content:

Decision Support Logic Source

Source reference for Decision Support Logic - exactly one of the following must be provided: - url (url data type): URL to retrieve DecisionSupportLogic definition from input/ or external source - canonical (canonical data type): Canonical URI pointing to the DecisionSupportLogic definition - instance: Inline DecisionSupportLogic instance data

Dublin Core Metadata Element Set

Logical Model representing Dublin Core metadata elements as defined at https://www.dublincore.org/specifications/dublin-core/dcmi-terms/

Digital Adaptation Kit (DAK)

Logical Model for representing a complete Digital Adaptation Kit (DAK) with metadata and all 9 DAK components

Non-Functional Requirement (DAK)

Logical Model for representing non-functional requirement from a DAK

Core Data Element Source

Source reference for Core Data Element - exactly one of the following must be provided: - url (url data type): URL to retrieve CoreDataElement definition from input/ or external source - canonical (canonical data type): Canonical URI pointing to the CoreDataElement definition - instance: Inline CoreDataElement instance data

Program Indicator (DAK)

Logical Model for representing Program Indicators from a DAK. Core set of indicators that need to be aggregated for decision-making, performance metrics and subnational and national reporting.

Health Interventions and Recommendations (DAK)

Logical Model for representing Health Interventions and Recommendations from a DAK. Overview of the health interventions and WHO, regional or national recommendations included within the DAK.

Decision-Support Logic (DAK)

Logical Model for representing Decision-Support Logic from a DAK. Decision-support logic and algorithms to support appropriate service delivery in accordance with WHO clinical, public health and data use guidelines.

User Scenario Source

Source reference for User Scenario - exactly one of the following must be provided: - url (url data type): URL to retrieve UserScenario definition from input/ or external source - canonical (canonical data type): Canonical URI pointing to the UserScenario definition - instance: Inline UserScenario instance data

Health Interventions Source

Source reference for Health Interventions - exactly one of the following must be provided: - url (url data type): URL to retrieve HealthInterventions definition from input/ or external source - canonical (canonical data type): Canonical URI pointing to the HealthInterventions definition - instance: Inline HealthInterventions instance data

User Scenario (DAK)

Logical Model for representing User Scenarios from a DAK. Narratives that describe how the different personas may interact with each other.

Program Indicator Source

Source reference for Program Indicator - exactly one of the following must be provided: - url (url data type): URL to retrieve ProgramIndicator definition from input/ or external source - canonical (canonical data type): Canonical URI pointing to the ProgramIndicator definition - instance: Inline ProgramIndicator instance data

FHIR Schema Base (SMART Guidelines)

Base logical model providing the common schema metadata interface inherited by all SMART Guidelines logical models. Every SMART Guidelines logical model schema derives from this base, which documents the shared FHIR and JSON-LD metadata properties used by the JSON Schema generation pipeline.

Generic Persona (DAK)

Logical Model for representing Generic Personas from a DAK. Depiction of the human and system actors. Human actors are end users, supervisors and related stakeholders who would be interacting with the digital system or involved in the clinical care, public health or health system pathway.

Functional Requirement (DAK)

Logical Model for representing functional requirement from a DAK

Test Scenario Source

Source reference for Test Scenario - exactly one of the following must be provided: - url (url data type): URL to retrieve TestScenario definition from input/ or external source - canonical (canonical data type): Canonical URI pointing to the TestScenario definition - instance: Inline TestScenario instance data

Test Scenario (DAK)

Logical Model for representing Test Scenarios from a DAK. A set of test scenarios to validate an implementation of the DAK.

Persona (DAK)

Logical Model for representing Personas from a DAK

Logical Model Enumeration Schema

JSON Schema defining the structure of the Logical Model enumeration endpoint response

Business Process Workflow (DAK)

Logical Model for representing Generic Business Processes and Workflows from a DAK. A business process is a set of related activities or tasks performed together to achieve the objectives of the health programme area.

Generic Persona Source

Source reference for Generic Persona - exactly one of the following must be provided: - url (url data type): URL to retrieve GenericPersona definition from input/ or external source - canonical (canonical data type): Canonical URI pointing to the GenericPersona definition - instance: Inline GenericPersona instance data

Functional and Non-Functional Requirements (DAK)

Logical Model for representing Functional and Non-Functional Requirements from a DAK. A high-level list of core functions and capabilities that the system must have to meet the end users' needs.

SUSHI Configuration Logical Model

Logical model defining the structure of sushi-config.yaml files used for FHIR Implementation Guide configuration. This model captures the essential metadata and configuration parameters needed for IG publishing.

Core Data Element (DAK)

Logical Model for representing Core Data Elements from a DAK. A core data element can be one of: a ValueSet, a CodeSystem, a ConceptMap, or a Logical Model adherent to SGLogicalModel. This is the ONE EXCEPTION to allowing FHIR R4 models into the DAK LMs.
