Reference metadata describe statistical concepts and methodologies used for the collection and generation of data. They provide information on data quality and, since they are strongly content-oriented, assist users in interpreting the data. Reference metadata, unlike structural metadata, can be decoupled from the data.

The quality assurance processes as described in 11.1. lead to qualitatively good data. When in the described registrations and processes errors are found, they are immediately corrected, thereby ensuring qualitatively good data sets. On the ensuing data sets, in this case the Resper tables, no other quality checks are performed.
