XML Schema Definition (XSD)

Extensible Markup Language (XML) Schema Definition is a World Wide Web Consortium recommendation that specifies how to describe the elements in an XML document formally. An XSD is used to verify that the content of an instance adheres to the definitions established for that object. 1EdTech creates XSDs for those standards that will use XML as the data exchange format. These XSDs are used as part of the conformance and certification testing process. The 1EdTech standards that use XML/XSD include Metadata, Common Cartridge, QTI/APIP, and OpenVideo Metadata.
