Clause 7 gives a conceptual, high-level data model of master data meant to show from above how the main entities of the models in ISO 8000-110 (exchange of characteristic data), 8000-120 (provenance), 8000-130 (accuracy) and 8000-140 (completeness) fit together, and possibly useful beyond master data. Clause 8 then surveys the parts of the series that deal with master data quality. See the official text for the full requirement.
