20. CBSO Project - Modules  Publication according to the legal mission  Template published by the NBB based on elements clearly defined in the law  Data processed in order to draw up statistics  Data must be validated through arithmetical and logical checks  The CBSO has developed a software used to input the data of annual accounts as alternative to private software  The output is a file compliant with the legal requirements

21. CBSO Project - Modules  Rendering  PDF files as output  Restrictive layout of the annual accounts  Use of metadata and pre-coded forms  Objectives  to insert most of the rendering parameters in the taxonomy instead of managing them outside,  to allow multilingualism  to reduce processing time when there is a new taxonomy version.

23. CBSO Project - Modules  Validation of instance documents  XML validation (well formed document)  XBRL validation (according to the taxonomy)  CBSO validation (supplementary protocol)  "In-house" developments  Too many specific checks  Waiting for "Formula" linkbase  To be integrated in a whole process

24. CBSO Project - Modules  "Data entry" application - SOFISTA-XBRL  Web application  Manual entry or upload  Validation included  Visualisation  "In house" developments  Based on the taxonomy for "standard" sections  Based on metadata for "specific" sections  Principles reused for Rendering module
