Validation Tool Introduction
Developers of systems that exchange data aligned to the Ed-Fi Standard Interchange Schema generally do so by exporting XML data files. The Ed-Fi Validation Tool provides an easy and convenient way for developers to validate the XML data files produced by a system against any published version of the Ed-Fi schema.
An advantage of XML is, of course, that data files can be validated locally against XSD. The Ed-Fi Validation Tool performs the same checks for well-formedness and validation against an XSD as those provided by a local XML parser. The Validation Tool also layers on additional data quality checks on the XML file, and provides an assurance that the file is valid against a published, standard version of the Ed-Fi schema.
This site contains documentation to help developers get set up and run tests using the Ed-Fi Validation Tool.
