This section covers allowable scenarios for subclassing existing entities in the Ed-Fi data model and extensions.

3.1. Subclass Domain Entities and Associations

Domain Entities and Associations may be subclassed when an entity needs additional data to support a specialization of the model. 

Currently, only the subclassing of abstract entities, such as EducationOrganization and GeneralStudentProgramAssociation (formerly StudentProgramAssociation in v2.x) and subclassing of composite parts classes (sometimes referred to as "common types", e.g., Ed-Fi Address or MeetingTime) , is supported.*

• MUST NOT contain any identity properties.
• MUST contain at least one property.
• SHOULD NOT contain properties included in the parent entity unless additional context is provided.
• SHOULD follow the same naming conventions as are applicable for the parent entity.
• MUST subclass domain entities and associations only.
• MUST NOT subclass a subclassed entity.
