This section covers allowable scenarios for composing and revising XML interchanges based on the Ed-Fi Unifying Data Model.

4.1 Compose New XML Interchange Schema

An Ed-Fi interchange schema is an XSD file that groups entities together for bulk data exchange.

  • MUST contain at least one domain entity or association.
  • MAY contain multiple domain entities and/or associations.
  • MUST NOT contain any cardinality statements.
  • MUST contain basic documentation.
  • SHOULD NOT contain "Interchange" in the name.
  • MAY contain extended documentation and use case documentation.

4.2. Extend XML Interchange Schema

The core set of Ed-Fi Standard Interchange Schema can be modified to include new or extended entities.

  • MUST contain at least one domain entity or association.
  • MAY contain multiple domain entities and/or associations.
  • MUST NOT contain entities included in the parent interchange.
  • MUST NOT contain any cardinality statements.
  • MUST NOT contain entity-level documentation (including extended and use-case documentation).
