Validation of latest changes

Conformity with the bibliographic metadata scheme. Accuracy is the degree to which the catalogue records conform to the syntax, the semantics, the rules and guidelines of the metadata schema (including the locally defined data elements). For those metadata fields which are not defined in the metadata schema's available documentation the tool is not able to decide if the data are correct or not. The page gives an overview and details of the captured issues. The user can check each individual records haveing a particular problem, and download their identifiers.
