Data Formats

Overview
Fusion Registry accepts and outputs datasets in a number of formats. When consuming data, the Fusion Registry will analyse the dataset to try to determine what data format it has received, so that it is able to direct it to the right reader. All datasets are read by the Fusion Registry in excatly the same way, so any data processing performed on a Dataset is the same, regardless of the input Data Format.
When querying for data from the Registry web service, or performing a Data Transformation via the Web service, the output data format is described using the HTTP Accept Header which describes the required data format.
HTTP Accept Headers
SDMX Formats
SDMX Fomats are supported as described by the web services specification
Accept Headers
| Accept Header | Format |
|---|---|
| application/vnd.sdmx.data+json;version=1.0.0 | SDMX JSON |
| application/vnd.sdmx.data+csv;version=1.0.0 | SDMX CSV |
| application/vnd.sdmx.data+edi | SDMX EDI |
| application/vnd.sdmx.structurespecificdata+xml;version=2.1 | Structure Specific (2.1) |
| application/vnd.sdmx.structurespecificdata+xml;version=2.0 | Compact (2.0/1.0) |
| application/vnd.sdmx.genericdata+xml;version=2.1 | Generic (2.1/2.0/1.0) |
CSV Formats
There are a number of CSV 'flavours' supported by Fusion Software, including the SDMX-CSV format which is an official SDMX data format. It is recommended to use the SDMX CSV format version 2 if you cannot decide which format to use.
The following Formats and correspoding VND Headers are supported:
- SDMX-CSV application/vnd.sdmx.data+csv
- Fusion-CSV application/vnd.csv
- Fusion-CSV-TS application/vnd.csv-ts
Each VND Header can then take the additional arguments of, note SDMX-CSV only supports a subset of these arguments or supported values.
| Argument | Description | Supported Values | Default | Supported Formats |
|---|---|---|---|---|
| version | the version of the format | 1.0.0, 2.0.0 SDMX-CSV only | 1.0.0 | SDMX-CSV, Fusion-CSV, Fusion-CSV-TS |
| timeFormat | values are converted to the most granular ISO 8601 representation taking into account the highest frequency of the data in the message |
original or normalized | original | SDMX-CSV |
| labels | output both code/concept ids and the respective labels in the specified language |
both/id/name | id | SDMX-CSV (with the exception of labels=name), Fusion-CSV, Fusion-CSV-TS |
| delimiter | the delimiter to use | comma/tab/semicolon/space | comma | Fusion-CSV, Fusion-CSV-TS |
| serieskey | include the series key as a column A series key is the concatenation of the dimension values for example A:UK:EMPLOYMENT |
include/exclude | exclude | Fusion-CSV, Fusion-CSV-TS |
| bom (since 10.3.1) |
Include or Exclude the Byte Order Mark (BOM). The BOM helps Excel interpret non Latin characters when opening a CSV file |
include/exclude | exclude | SDMX-CSV, Fusion-CSV, Fusion-CSV-TS |
Note:The Labels parameter can be used in conjuntion with the HTTP Accept-Language Header to indicate which language to resolve the labels in. If the labels are not available in the requested language, another language will be selected, defaulting to English.
Examples
application/vnd.sdmx.data+csv
application/vnd.sdmx.data+csv;version=1.0.0;
application/vnd.sdmx.data+csv;version=2.0.0;
application/vnd.sdmx.data+csv;version=1.0.0;timeFormat=normalized
application/vnd.sdmx.data+csv;version=1.0.0;timeFormat=normalized;labels=both
application/vnd.csv
application/vnd.csv;delimiter=tab
application/vnd.csv;timeFormat=normalized;serieskey=include
application/vnd.csv;version=1.0.0;labels=both
application/vnd.csv-ts
application/vnd.csv-ts;version=1.0.0;
application/vnd.csv-ts;version=1.0.0;labels=name
Data Reporting Template
There are two types of output when converting data to a Data Reporting Template format. The first is where the Data reporting template is constructed in the usual way, with the Universe of Data being derived from the Dataflow, and related Content Constraints. The second is where the Universe of Data is derived from the dataset being written into the Excel workbook. The default output is to base the Report Template Universe on the constraints, to change this behaviour, use the +partial indicator in the VND Header.
| Accept Header | Description |
|---|---|
| application/vnd.reporttemplate | Excel Report Template pre-populated with the data from a dataset.
|
| application/vnd.reporttemplate.ACY:BANKING(1.0) | This is an extension of application/vnd.reporttemplate, it tells the Fusion Registry which Reporting Template to use. Only required if there is more then one Reporting Template for the Dataflow(s) being written. |
| application/vnd.reporttemplate;DATA_PROVIDER=ONS | This is an extension of application/vnd.reporttemplate, it tells the Fusion Registry who the Data Provider is.
The Data Provider's Agency defaults to SDMX. If this is not true, use the syntax DATA_PROVIDER=ACY_ID.ONS Can be used in conjunction with other VND arguments such as the Report Template identifer. |
| application/vnd.reporttemplate+partial | This outputs the dataset conforming to the layout of the Report Template, but includes only the worksheets, and observation cells for which there is data in the dataset. There is no main worksheet.
A Data Provider reference is not necessary, however information about which Report Template to use can be provided using the .ACY:TEMPLATE_ID(1.0) syntax. |
