SDMX sponsoring organizations wish to increase and formalise the participation of the SDMX User Community (statistical offices, central banks and other national and international organisations dealing with official statistics) in the management and development of the SDMX Technical Standards and the SDMX Content oriented Guidelines. Established in 2011, the SDMX Technical Standards Working Group (SDMX TWG) and the SDMX Statistical Working Group (SDMX SWG) are meant to provide the forum for this active participation. For each of the two working groups 20 participants from a broad range of countries and from different statistical organisations or central banks were selected (please see the list of members of these two working groups hereafter). The working groups will develop their work programmes based on the input from the SDMX User Community. More information will be posted in due course on the SDMX Website and on the SDMX User Forum.
