SDMX-EDI

Statistics Directorate    
Definition:
EDIFACT format for exchange of SDMX-structured data and metadata.

Context:
The SDMX-EDI format is drawn from the GESMES/TS version 3.0 implementation guide, as published as a standard of the SDMX initiative. (source, p. 10)

SDMX-EDI is a message designed for the exchange of statistical information between organisations in a platform independent manner. The message implements a data exchange model (SDMX Information Model) which provides for the exchange of time series identified through a multi-dimensional key and a variety of associated metadata.

It employs an appropriate GESMES profile and EDIFACT syntax. Though GESMES is a generic statistical data model which affords sufficient flexibility to describe syntactically virtually any statistical data model, SDMX-EDI has a fixed syntax. This allows partner institutions to design and to build the applications needed to "read" and "write" SDMX-EDI messages, avoiding intermediate files and special translators; the design of the read/write applications is further simplified by eliminating genericity which is not needed when exchanging time series data.

Due to the fixed syntax, in most cases, the rules used in SDMX-EDI are stronger and more restrictive than those in generic GESMES. However, the current design allows the possibility of future enhancements and progressive generalisation, if this is needed, upon agreement of the parties involved.
