Meaning
Verification process of checking an XML document against a set of formal rules to ensure it is both well-formed and valid according to a specific schema. This procedure confirms that the document follows the correct syntax and contains all required data elements in the specified order. It acts as a quality gate for data exchange between different software systems.
Verification Method
Implementation of xml validation involves the use of a parser that reads the document and compares it to a DTD or an XML Schema. The parser checks for the presence of mandatory tags, the correct nesting of elements and the appropriateness of data types. If the document deviates from the rules, the validator generates a list of errors.
This automated check removes the need for manual inspection of data files.
Compliance Benefit
Reliability of data is significantly improved when every transaction is verified at the point of entry.
Industrial Application
Deployment of validation routines within a manufacturing execution system ensures that production orders are accurate before they reach the factory floor. Errors in part specifications or quantities are caught early, preventing waste and downtime. The process also supports the integration of diverse components from different suppliers into a single digital twin.
Continuous validation maintains the integrity of the digital thread throughout the product lifecycle.
