2. Case 1: Data reporting Receiver 1 Data 1 Sender Data 2 Receiver 2
Usually we’re involved to send data to more than one receiver . In some cases we have to send the same data in diffrent formats and diffrent way to serveral receivers . In addition , the receivers exchanges part of this data that’s replicated . So we lost many time to adopt structure with a poor metadata ….

3. Case 2: Data Collecting Receiver 1 Trade Data 1 Sender Data 2

Data 2
Short term
In some cases , the entity who is in charge data reporting collects from several sources in many formats . So a harmonization of structure is stongly needed to be able to send data to “receivers” .
Receiver 2
Census

4. Background issues
Data being collected in multiple ways (surveys, files, web queries, metadata etc.);
Data being transmitted in various formats (paper, excel, flat files etc.)
Data being transmitted in various media ( , CD-ROMs, file uploads etc.);
Data being stored in various places (USB, hard drive, servers, cloud etc.);

5. Background issues
Multiple organisations collecting similar or same data;
Similar concepts in wording can have a different content;
Increasing burden on organisations (collection, maintenance and managing);
The intensive and manual nature of data collection;
Errors and inconsistencies;

6. Data exchange, How ? Dataset1 Sender Receiver Data Structure
Let’s see what we mean by sending /reporting datasets !
So we send values , variables , codes , facts …. That’s mean we have to send data (values) and metadata . But how we can understand the structure of my data by a wide users . May I add texts to explain ? Whitch vocabulary I will adopt ?

7. Data exchange, How ? Standard Message Common Vocablory List of Tools

Through
List of rule to harmonize message using Commun vocablory . To implement that we need list of tools . There’s SDMX repository of tools . Most of them are free and open source like SDMX RI
IT Infrastructure for exchange and sharing

8. Data exchange, How ?
SDMX is about changing from a multiple, diverse and complex exchange system, to a common, harmonised and standardised exchange system.
