      COMMISSION RECOMMENDATION
   
   of 23 June 2009
   on reference metadata for the European Statistical System
   (Text with EEA relevance)
   (2009/498/EC)
   THE COMMISSION OF THE EUROPEAN COMMUNITIES,
   Having regard to the Treaty establishing the European Community, and in particular Article 211 thereof,
   Whereas:
   
               (1)
            
            
               The European Statistics Code of Practice (1), intended for the national and Community statistical authorities enumerates 15 principles linked to the institutional environment, statistical processes and statistical output.
            
         
               (2)
            
            
               Principle 15 of the European Statistics Code of Practice deals with accessibility and clarity of European Statistics, also emphasising that the accompanying metadata should be documented according to a standardised metadata system.
            
         
               (3)
            
            
               Reference metadata are an integral part of the metadata system of each statistical authority.
            
         
               (4)
            
            
               With the adoption of the European Statistics Code of Practice the national and Community statistical authorities have committed themselves towards high quality statistics which also requires more transparent and harmonised reporting on data quality.
            
         
               (5)
            
            
               In the framework of the SDMX initiative on common technical and statistical standards for the exchange and sharing of data and metadata launched by the Bank of International Settlements, the European Central Bank, the Community statistical authority (Eurostat), the International Monetary Fund, the Organisation for Economic Cooperation and Development, the United Nations and the World Bank the SDMX Content-Oriented Guidelines have been established which support the creation and implementation of harmonised reference metadata in the European Statistical System.
            
         
               (6)
            
            
               Considerable efficiency gains can be reached when the reference metadata are produced on the basis of a harmonised list of statistical concepts within the European Statistical System, while at the same time allowing national and Community statistical authorities to add more statistical concepts in particular statistical areas if needed.
            
         
               (7)
            
            
               Regulation (EC) No 223/2009 of the European Parliament and of the Council of 11 March 2009 on European Statistics (2) provides a reference framework for this Recommendation,
            
         HEREBY RECOMMENDS TO THE MEMBER STATES:
   
               1.
            
            
               National statistical authorities are invited to apply the statistical concepts and sub-concepts listed in the Annex when reference metadata are compiled in the different statistical areas and when reference metadata are exchanged within the European Statistical System or beyond.
            
         
               2.
            
            
               Additional statistical concepts should be added by national statistical authorities to the above list of concepts and sub-concepts if it is necessary for particular statistical areas.
            
         
               3.
            
            
               National statistical authorities are invited to regularly inform the Commission (Eurostat) of their application of the concepts and sub-concepts listed in the Annex.
            
         
      Done at Brussels, 23 June 2009.
