The SDMX format

All files that form a survey use the Industry standard XML format. To comply with international practices the dialect of XML used is called SDMX which stands for Statistical Data and Metadata eXchange.

A survey typically contains the following files:

The item list holds the tree with all items of the survey such as products and services. Item codes and names are contained in this file along with the hierarchy they form

The observations file is an SDMX (Cross sectional format) file that holds all the user observations for this survey dataset. This file is initially empty.

The metadata file is an SDMX keyfamily. It contains the metadata associated with survey such as countries, measurement units e.t.c

The last file is used by the DET for identification of the survey and default values.
