15. CoRD Task Force Meeting - Luxembourg X-DIS/XBRL Pilot Project | 4 June 2007 | Page 15 Tasks of X-DIS/XBRL Pilot Project - Phase 1 TaskTask NameTask Description Task 1 Mapping of existing taxonomies First of all an inventory of all relevant taxonomies at the time of the start of this pilot will have to be established. A detailed line by line mapping exercise should be performed between the requirements in the relevant statistical legislation and these taxonomies. This will help determine whether the statistical requirements are not already available in the existing taxonomies. Task 2 Monitoring XBRL developments Other than the detailed analysis of the taxonomies, developments in existing XBRL projects in statistical and accounting domains should be monitored very closely. This will avoid duplicating efforts. Throughout the duration of the project, Eurostat should be kept informed of these developments and the possibilities for synergy with the pilot project should be outlined. Task 3 Creation of a statistical taxonomy Based on the outcome of task 3.1., it should be determined whether or not the creation of a statistical taxonomy is useful and desirable. It should also be established if a comprehensive taxonomy (encompassing all European statistical reporting requirements) should be created rather than taxonomies per statistical field (SBS, STS, BOP etc.). Member States could afterwards extend these taxonomies in order to integrate their own additional reporting requirements. Task 4 Test phase As suggested in the feasibility study, the taxonomies should be tested in a live environment with the cooperation of 2 or 3 NSIs. Each participating NSI would have to involve a sufficiently large number of enterprises in order to estimate the total population for which the taxonomies could be acceptable and subsequently used. A broad variety of enterprises should be covered (SMEs and listed companies, enterprises in different business lines, companies who are part of a group or consortium and individual businesses). In this phase it should also be investigated how XBRL reporting of microdata from enterprises to NSI can be brought in line with the subsequent SDMX reporting of aggregated data from NSI to Eurostat. Task 5 Acceptance If the test phase proves successful, it has to be established if XBRL can be proposed to the NSIs as a tool for their data collection from enterprises and whether the latter would be inclined to adopt it. Aspects of respondent burden, initial investment, and media to be used for data exchange and running costs will have to be investigated. Task 6 The use of XBRL in surveys by the NSIs A further issue to investigate is the use of XBRL in surveys. Is it realizable for enterprises to no longer send their information to the NSI, posting data instead on their websites? The data would be ‘picked up’ by the NSI via a web search engine with an XBRL-tag as search criterion.

16. CoRD Task Force Meeting - Luxembourg X-DIS/XBRL Pilot Project | 4 June 2007 | Page 16 Tasks of X-DIS/XBRL Pilot Project - Phase 2 TaskTask NameTask Description Task 1 New Modules of the European Taxonomy The European XBRL taxonomy, currently limited to the SBS framework, needs to be extended to other statistical business frameworks. Eurostat will indicate two or three new statistical areas to be analysed and for which new modules of the European statistical taxonomy will be developed. Reuse of common concepts between modules and a modular approach to taxonomy design are highly recommended. Task 2 Extended testing of European SBS taxonomy The modular European statistical taxonomy needs to be tested in real cases, to further prove its reusability across the European Statistical System. Tests will comprise the generation of XBRL reports by companies, transmission of reports to NSI, validation of reports and loading of data into NSI's production systems. The SBS module, developed in the framework of contract No 14400/2005/005-2006/066 – CS 1, already tested in collaboration with BE, ES and NL, will have to be tested with two or three more countries indicated by Eurostat among the members of the XBRL Task Force. The new domain-specific modules will have to be tested in all countries (BE, ES, NL and the new ones). Task 3 Analysis of Sectoral XML Standards Potentially Interesting for Statistics Many custom XML standards have been developed or are being developed by industrial and business communities. The aim of this task is to point out which ones could be of potential interest for primary statistical data collection (from businesses to NSI), in the spirit of the work done with XBRL.
