CBSO Project - Communication
Extensive information about the taxonomy is available on the website of XBRL Belgium.
Taxonomy files Instance documents based on real cases a user guide a "viewer" allowing to run over the taxonomy in an efficient
and pleasant way
Technical documents Protocol New template
Road shows to professionals Accountants associations Software vendors
6
CBSO Project – Interaction with Software vendors
Why they were involved Private companies produce 60% of the annual accounts filed
electronically The success of the project depends also from their ability to
produce valid instance documents as from April 2007 Software vendors were associated to the project from the
beginning
How they were involved Feedback on the taxonomy through the WG Personal contact to propose a "test service" Application available in a test environment as from January 2007

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
Rendering Module
Validation Module
9
CBSO Project - Modules
Belgian Gaap
Individual annual accounts are drawn up according to the Belgian Gaap
Assistance
Free software used to input the data of annual accounts as alternative to private software
The output is a file compliant with the legal requirements
Taxonomy
Data Entry Module
10
Taxonomy - Description
be-fr-pfs-ci-2006-10-01 According to Belgian GAAP Financial Reporting Primary Financial Statements Commercial and Industry
Technical assumptions Compliant spec 2.1 and FRTA Multilingual Modular structure

Taxonomy - Architecture
12
Taxonomy - Experiences
Tools Taxonomy development - Fujitsu Taxonomy validation - Fujitsu
- DecisionSoft- UBmatrix
Instance document creation - Fujitsu (sample)
Conclusions Generic tools essential considering the complexity of
the syntax The tools are not complete and give different results
13
Data Entry - Features
"On line" application Allowing a company to fill in the data of its annual
account Allowing upload of an XBRL file build with another
application Validating the data according to technical and
legal requirements Displaying the annual account as it will be
published according to the legal template Creating a valid output file ready to be filed
14
Data Entry - Layout (1)
15
Data Entry - Layout (2)
16
Data Entry - Experiences
Complete "In house" development Tools too generic => need for specific functions Tuple handling
Solution Most of the sections are automatically generated from
the taxonomy Some specific sections (identifying data or social
balance) use "metadata" to be generated Methodology reused for Rendering module
17
Validation - Features
Three levels of validation XML validation XBRL validation against taxonomy be-fr-pfs-ci-xxxx NBB validation containing specific rules but also
arithmetical and logical checks
Technical specifications published Software vendors must produce instance documents
answering to all specifications Frequent contacts with software vendors (Feedback
about taxonomy, tests sessions, …)
18
Validation - Experiences
Module used at two levels To validate an instance document in the data entry
application To validate an instance document in the filing
application
"In house" development Too many specific checks "Formula" not yet available To be integrated in an existing process
19
Rendering - Objectives
Legal mission Annual accounts have to be published according to a
formal template Availability as PDF file
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.

Versioning - Requirements
Versioning First changes with be-fr-pfs-ci-2008-04-01 New taxonomy = New name
Corrections Legal changes
Use of a Definition linkbase as intermediate table from a version to the next one

CBSO Project - Issues
Urgent needs Versioning Formula Rendering specifications
Dangers In the absence of specifications coming from XBRL
International, developers will imagine specific solutions which will go against harmonization
