A schematic view of the information model can be seen in Figure 2. Figure : SDMX Information Schematic View ESMS The Euro SDMX Metadata Structure (ESMS) contains the description and representation of statistical metadata concepts to be used for documenting statistical datasets and for providing summary information useful for assessing data quality and the production process in general. The broad concepts used are based on SDMX cross- domain concepts as published in the SDMX Glossary (last version published in 2016). Its structure (i.e. allowed content) is defined using an SDMX Metadata Structure Definition. The ESMS is addressed to the countries which are part of the European Statistical System and was embedded in a European Recommendation published in 2009. It is implemented both at Eurostat and at national level: the application of the concepts and sub concepts at European level and at national level is stated in the ESS guidelines. The information to be entered is normally free text, but some coded elements may be introduced in the future: this is indicated in the column "representation" below. The ESMS allows the creation of different output files comprising information related to all the concepts listed or a subset of those concepts. These output files can be used for different purposes (data dissemination, quality reporting, etc.). A fragment of the ESMS specification (release 4, 2014) is shown in Figure 3. Figure : Fragment of ESMS specification Another standardised metadata structure currently in use is the Standard Quality “ESS Report Structure” Quality reports are produced and partly disseminated by Eurostat in this format. Eurostat has also recently introduced a "Single Integrated Metadata Structure" (SIMS), which represents the union of referential metadata attributes coming from ESMS and ESQRS, providing an integrated framework of concepts on quality assessment and more general reference metadata. Open Data standards and application profiles W3C DCAT The basis for DCAT-AP is the specification of the Data Catalog Vocabulary (DCAT). DCAT was developed in the period from June 2011 through December 2013 by the Government Linked Data Working Group. The specification was published as a W3C Recommendation in January 2014.
