5. The SDMX Components SDMX Information model Content-oriented guidelines
Describes the data/metadata exchange
Defines the main SDMX components and a set of rules
Content-oriented guidelines
Defines the standard in terms of content: statistical concepts, cross-domain code lists, statistical domains, Metadata Common Vocabulary
IT infrastructure for exchange and sharing
Describes the main modes of data exchange: push mode, pull mode and the hub mode
SDMX is not just a transmission format, but also cares for statistical harmonisation and business process integration

14. What can data provider (Member states) do?
Use and reuse all SDMX IT infrastructure already being in place (e.g. the SDMX Reference Infrastructure already being installed in most Member states);
Discuss the SDMX implementation actions (i.e. the technical and statistical harmonisation of the data sets in the competent working groups;
Embark into SDMX based data and metadata exchange as soon as this is possible for particular statistical domains;
Identify next statistical domains in social statistics for SDMX implementation (trigger: changing data sets, changing international data flows etc.).
