DAK API Documentation Hub

This page provides comprehensive documentation for 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.

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.

This documentation hub is automatically generated from the available schema and API definitions.
