## EuVac Models Overview

MyHealth@EU Vaccination logical models refine the EHDS logical information models provided by the Xt-EHR project. These models use obligations on the logical models to highlight the elements identified by the MyHealth@EU Functional Requirements. Three types of obligations are defined based on the MyHealth@EU requirements:

* **Mandatory**: the data element must be provided
* **Required**: the data element must be provided, although exceptional justifications can be provided
* **Optional**: the data element can be completely omitted

These obligations are implemented using the following rule sets:

* `ObligationMandatory` - SHALL:handle for mandatory elements
* `ObligationRequired` - SHOULD:handle for required elements
* `ObligationOptional` - MAY:able-to-populate for optional elements
