PRE-LOAD AND LOAD VALIDATION RULES

The PEIMS Data Standards XML schema ensures that the data files from school districts adhere to a common structure and consist of valid elements and attributes. An XML extract file must be syntactically perfect, or it is rendered as unacceptable by an XML parser.

Restrictions control acceptable values for XML data elements. In combination with an element’s declared data type, restrictions enable the XSD validation process not only to validate the structure of the XML file but also to validate the data values contained within the file against its XML schema definition. The XML schema also enforces length restrictions for a given element by either an exact length, minimum length, or maximum length. Many simple type elements within the PEIMS XSD have a restriction that limits the domain of acceptable values.
