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), 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.
