SNA data exchange in ESCB context Use of EXDI (ESCB data exchange infrastructure) SDMX reporting format supported: SDMX-EDI (Gesmes/TS) SDMX-ML compact format version 2.0 SDMX-ML structure specific version 2.1 Starting date for the transition period: from September 2013 onwards MUFA test transmission – November 2013 Use of the test environment for the new SNA DSDs for the test transmissions and the production for the current SNA flows

Data flows A data flow is characterised by: a Data Structure Definition (DSD) constraints = list of expected series keys / combination of valid codes in series key dimensions providing and receiving institutions a reporting deadline Data flows are equivalent to the Data Set Identifier in SDMX/EDI terminology

Compatibility: SDMX-EDI/SDMX-ML SDMX-EDI and SDMX-ML data files must be easily convertible into each other The data model underlying the pure data part of data files is the same for SDMX-EDI and SDMX-ML Easy conversion between the two formats requires the same information model also to apply to the information contained in the header of the file The mandatory pieces of information for SDMX-EDI and their counterparts in SDMX-ML, 2.1 in the example below, are highlighted in bold red

SNA data flows At this stage, some technical details still need to be further clarified and agreed between IOs in terms of: Data flow definitions from reporting institutions to IOs between IOs Data file content Updates and Revisions data files (U&R) versus full refreshment Transmission of attributes Data transmissions to ECB using the new SDMX-NA DSD will take place from September 2014 onwards
