2. Development of metadata in the National Statistical Institute of Spain Background INE has been working on metadata for 10 years Closely following the METIS and Eurostat working groups´ developments During these 10 years, prototypes have been developed for repositories of concepts, questions and classifications related to different surveys carried out by the INE 2

3. Development of metadata in the National Statistical Institute of Spain Background Before: Metadata were not considered a part of the process. Now: Process is defined in terms of GSBPM Metadata will be considered by the Regulations. Metadata are integrated in the process 3

19. Development of metadata in the National Statistical Institute of Spain Implementation plan April 2012: submitted to the High Council on Statistics Beginning of 2013: Concept repository available on INE’s web site End of 2013: Classification repository Beginning of 2014: It would be possible to access the structural metadata base The structural metadata 19

21. Development of metadata in the National Statistical Institute of Spain Process metadata The Board of Directors, on its meeting of March 8 th, 2012, approved a standard promoting the use of the GSBPM as the language for describing the production model of the different statistical operations. 21

22. Development of metadata in the National Statistical Institute of Spain Pilot tests have already been carried out: Description of the process for the production of Retail Trade Indices Survey on Equipment and Use of Information and Communication Technologies in Households Process metadata General remarks: Different kind of tasks have to be distinguished in the production process: A. Monthly tasks: These tasks are basically data collection, editing, imputation and dissemination. B. Yearly tasks: B1. Yearly tasks related to the sample rotation. B2. Yearly tasks related to other potential changes in the survey, like data collection improvements. C. Other sporadic tasks, like a change of questionnaire 22

23. Development of metadata in the National Statistical Institute of Spain 1.The unit in charge of producing the index described the different tasks in terms of GSBPM A lack of information on data, people involved, used software, time used… was noticed 2.The metadata unit proposed some items (as a minimum) for covering this lack of information GSIM could solve this problem Process metadata Reflections: 23
