ESS Standard for Quality Reports
The ESS Standard for Quality Reports Structure (ESQRS) contains the description and representation of statistical metadata concepts to be used for providing detailed information for assessing data quality. The broad concepts used are compatible with the SDMX cross-domain concepts and with the common terminology as published within the SDMX Glossary (2016). The detailed quality concepts are based on the ESS Standard for Quality Reports (ESQR) from 2009. The ESQRS is addressed to the European Statistical System. It is implemented at Eurostat and at national level: the application of the concepts and sub concepts at European level and at national level are provided in the ESS Handbook for Quality Reports (EHQR) from 2014 and the ESS Guidelines for the implementation of the ESS Quality and Performance Indicators from 2014. The Single Integrated Metadata Structure v2.0 combines both underlying reporting structures (ESMS 2.0 and ESQRS 2.0), and is the standard for quality reporting according to Article 12 of Regulation 223/2009 on European statistics.
