Quality Levels
Four levels: data, descriptions, the catalog as a service and the system of catalogs. A high score on one leaves the others as they were.
Quality Metrics
Which shares to calculate for a catalog, how a share is built and which numbers do not show what to fix.
Methodologies and Rankings
Which score answers which question: a file, a record, a catalog in the European federation or a country.
Catalog Self-Audit
One pass through a catalog: a sample of descriptions, the files, publisher coverage and a page with a queue for the month.
