### Using the DAK API

#### Schema Validation

Each JSON Schema can be used to validate data structures in your applications.

* 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.

#### Integration with FHIR

All schemas are derived from the FHIR definitions in this implementation guide.

#### API Endpoints

The enumeration endpoints provide machine-readable lists of all available schemas.
