##

A **FormDef** describes a type of form that can occur in a study. The Repeating flag indicates that this type of form can occur repeatedly within a containing study event.

**FormDef**는 스터디의 양식 유형을 설명한다. Repeating 플래그는 이러한 양식 유형이 스터디 이벤트 내에서 반복적으로 발생할 수 있음을 나타낸다.

{% hint style="info" %}
특정 스터디에서 **FormDef**로 하나의 Form이 정의되고 [StudyEventDef](/3.1.1.3-metadataversion/3.1.1-study/3.1.1.3-metadataversion/3.1.1.3.3-studyeventdef.md)에서 앞서 정의된 Form을 [FormRef](/3.1.1.3-metadataversion/3.1.1-study/3.1.1.3-metadataversion/3.1.1.3.3-studyeventdef/3.1.1.3.3.1-formref.md)로 불러온다. 이 때 서로 다른 StudyEvent에서 같은 Form을 참조하고 싶은 경우 Form이 반복되어 사용되므로 해당 Form의 **Repeating** 속성 값을 Yes로 지정하면 된다.
{% endhint %}
