Different use-cases and different periodicities of data exchange require different interchange schema. Ed-Fi Data Standard v2.1b contains a set of 21 proposed Standard Interchange Schemas to handle common data exchange use cases, including basic student profile information, attendance records, assessment results, program participation, and many other information-transfer scenarios.
The proposed v2.1b introduces few changes from v2.0 schemas, beyond introducing new, proposed domain entities into existing interchange schemas where applicable.
The Ed-Fi Standard Interchange Schemas are XSD files, all of which utilize the domain entities and other types defined in the Ed-Fi Core schema. Through field-testing, the standard Ed-Fi schema definitions provide a rigorous structure for data, but allow a reasonable degree of flexibility to account for different levels of source data availability.
