Overview
The SDMX-CSV Data format is an official SDMX format described on the SDMX GitHub Repository. It comes in 2 flavours, the older version 1.0.0 format or the newer version 2.0.0 format. Metadata Technology recommend using the newer version 2.0.0 format.
It can be used as both an import and export format for the Fusion Metadata Registry, and an export format for the Fusion Edge Server and Fusion Data Browser.
The format is comma separated format where each row describes a single Observation value. The columns describe each component of the Observation value, reflecting the Components in the Data Structure Definition.
The dataset can contain both Code labels, in addition to the Code IDs. The order of the columns is not important, however each column header will contain the ID of the corresponding Component. The first column must be called Structure (unless using version 1.0.0) where each row contains the URN postfix of the Structure that the dataset is for.
Formatting Using Query Parameters
The following URL parameters can be used in a RESTful query for Fusion-CSV data.
- format = sdmx-csv
- labels = id | name | both | (id is default)
- timeFormat = normalized
- bom = include | exclude (Include or Exclude the Byte Order Mark (BOM).
The BOM helps Excel interpret non Latin characters when opening a CSV file)
| Query Parameter | Values | Description |
|---|---|---|
| format | sdmx-csv | Required to output the dataset in csv-ts format |
| labels | id or name or both default id |
Defines if labels or ids should be used on output, if both is selected then there are 2 columns per coded component (one for Id one for the label) |
| timeFormat | normalized | outputs the time in the highest-frequency. E.g if annual data is supplied, but the highest frequency is daily, then 2001 would become either 2001-01-01 or 2001-12-31 depending on whether startPeriod or endPeriod is used. |
| serieskey | include or exclude default exclude |
If true, a series key column will be included in the output |
| bom | include or exclude | (Include or Exclude the Byte Order Mark (BOM). The BOM helps Excel interpret non Latin characters when opening a CSV file) |
The output type "all-lang" will output both id and name and will add an element to the start of each row which will be the language. For each series and each language a row will be output where the name in the row is for the specified language. If there is no name value for that language, the name is simply not output. See below for an example output/
Normalized Time If the parameter value is normalized then the TIME_PERIOD values are converted to the most granular ISO 8601 representation taking into account the highest frequency of the data in the message
Note: The same formatting can be applied using HTTP Accept Headers as opposed to query parameters.
Example
An example query using the format request parameters, HTTP Accept Headers can also be used to define the same format.

An example dataset with IDs only, spaces have been added to this example to assist readability.

Example of SDMX CSV version 1.0.0
An example query using the format request parameters, HTTP Accept Headers can also be used to define the same format.
