Design

• Based on our already highly structured documents
• Use existing building blocks
• Hybrid design
• dimensional and non-dimensional patterns

15
Design

• Why dimensions?
• Multidimensional structures
• There are several related types of forms which
  provide important reuse with dimensions
• The pattern non-limitative list is frequently
  used in the forms
• Taking future evolutions in the XBRL domain,
  certainly the formula linkbase, into
  consideration, the use of dimensions is preferred

16
Design

• Business requirements
• 100 XBRL compliant
• Comprehensible
• Consistent and stable

• Aligned with other taxonomies used in the Belgian
  jurisdiction
• Avoid redundant concepts
• Performance
• Flexible

  more time to get a qualitative and
  future-oriented taxonomy
• Iterative process and perform regular quality
  reviews with business and technical experts

25
Our experience

• Involve business and management
• Communicate when quality and stability are
  sufficient
• Involve and communicate with end-users because
  their participation is a key to future success

• A qualitative and future-oriented taxonomy is the
  key to success for XBRL implementations.
  Cooperation with experienced parties creates
  numerous opportunities to make better and more
  solid choices with regard to architecture and
  design. Moreover, cooperation will lead to better
  mutual optimization of taxonomies, for instance
  by using existing building blocks. We will share
  our experience with you and allow you to look
  into the near future of XBRL in the FPS Finance.
