CKAN Validation provides comprehensive data validation capabilities powered by the Frictionless Framework library. It automatically validates tabular data files (CSV, Excel, etc.) and provides detailed validation reports with structural and content-level error detection. The extension supports both synchronous and asynchronous validation modes, custom data schemas using Table Schema specification, and configurable validation options. Features include validation badges in resource listings, detailed error reports with row/column context, support for private datasets, and integration with CKAN’s background job system. The extension helps ensure data quality and provides users with actionable feedback about data issues before publication.
