Design of Surfi templates
SENSITIVITY LEVEL : PUBLIC
Examples of templates provided by business-oriented staff for statistical and risk assessing purposes ( Accounting, Statistics, Monetary Directorates, and French overseas institution…)
- In cartridge headers, major dimension breakdown
- In column headers, dimension breakdown
- In some rows, dimension breakdown
Separate file for elements belonging to « Accounting class data tree » (9 primaries generated)

Design of Surfi templates
SENSITIVITY LEVEL : PUBLIC
Examples of templates transformed for automation purposes
- balance between number of « excluded hypercubes » and ELR (Extended Link Role) with no Open Hypercubes
- use of a specific colour code to identify dimension names and their values, facts, forbidden data
- use of a short code for name handling (each code is bound to a tooltip containing the name of the element, the dimensions and dimension values associated)
- use of specific files for dimensions and hypercubes

Automatic generation of the taxonomy
SENSITIVITY LEVEL : PUBLIC
Command line program written in Perl for Taxonomy and formula linkbase
Input files : Colored templates + 1 file for hypervolumes and 1 file for dimensions + 1 configuration file with default values for each template (default type, period value, balance value, prefix and label for namespaces…)
4 executable files
- TraitArbo.exe (TAx.bat) for generation of 9 primary taxonomies from accounting classes
- GenTaxoDim.exe (GTDx.bat) for generation of dimensions
- TraitGab.exe and GenTaxoTransp.exe (TGx.bat GTTx.bat) for generation of child taxonomies (primaries, and templates)

Formula linkbase
SENSITIVITY LEVEL : PUBLIC
4 types of SURFI formula
- Simple aggregation (F1) : equal relation between facts, all elements are primary elements which have the same context and unit ex: Calculation Link in all tables
- « Of which » assertion (F2) : like F1 but “greater than or equal to” relation
- Dimensional aggregation (F3 F4) : primary item(s) with same concept name, identifier, period, unit and dimension with each domain member
- Simple formula : addressing any element of the XBRL instance. The name, dimensions, dimension values are explicitly indicated

Parameters to deal with
- Tolerance Margin : for some checks
- Different remittance date : different facts and different checks
- Missing or forbidden facts : precondition testing (presence of total and one of the subtotals
- Simple formula : addressing any element of the XBRL instance. The name, dimensions, dimension values are explicitly indicated
