IFRS Taxonomy Framework
8
Release Timeline

• IFRS taxonomy reflects standards and
  interpretations effective as at the taxonomy
  release date
• IFRS taxonomy architecture is aligned with the
  IASB timeline for releasing of the standards
• Modelling of standards and interpretations as
  published by the IASB within one yearly IFRS
  taxonomy release
• Consideration of early adoption standards and
  their inclusion in the reporting process

9
Taxonomy Schemas

• Single schema approach
• Additional roles schema

Namespace prefix Namespace URI Use
ifrs http//xbrl.iasb.org/YYYY-MM-DD/ifrs/ Main namespace for all IFRS concepts
Role URI Definition
http//xbrl.iasb.org/ifrs/role/statement disclosure/ unique name Disclosure Statement unique name
10
Taxonomy Linkbases

• English label linkbase referenced from core
  schema
• Other than English label linkbases modularised
  according to languages
• Presentation, calculation, definition, reference
  modularised according to standards and
  interpretations
• Presentation, calculation and definition
  linkbases placed in single files for each
  statement or disclosure

11
Reference Linkbase
Reference role Use
http//xbrl.iasb.org/ifrs/role/recognitionRef Reference for recognition and derecognition of the concept
http//xbrl.iasb.org/ifrs/role/commonPracticeRef Reference for common practice disclosure relating to the concept. Replaces reference to IFRS common practice (IFRS-CP) enabling common practice reference to a standard or interpretation.
12
Reference Linkbase
Reference part Use
IssueDate Issue date of the standard or interpretation
Name IFRSIASIFRICSICXBRL
Number Number of the standard or interpretation
Section Sections of standard or interpretation.
Paragraph Paragraph in the standard
Subparagraph Subparagraph of a paragraph
Clause Subcomponent of a sub paragraph
Subclause Subcomponent of a clause in a paragraph
13
Presentation Linkbase

• No changes in the expression of hierarchies in
  the presentation linkbase comparing to previous
  IFRS-GP taxonomy releases
• Enhancement to the way of expressing two
  dimensional tables
• Use of a double extended links in the
  presentation linkbase (for horizontal and
  vertical alignment) with additional attributes in
  order to express and render changes tables
• Alternative use of dimensions for changes tables

14
Definition Linkbase

• Main uses of dimensions
• segment reporting (IAS 14 and IFRS 8)
• reconciliation (restatements)
• first time adoption
• fair presentation override
• Only explicit dimensions (defined or open)
• Hypercubes are open and where possible default
  dimension specified

15
New XBRL Technologies

• Versioning
• Versioning solution as additional information for
  the IFRS 2008 taxonomy
• Rendering
• Tabular rendering in presentation linkbase
• Instance rendering out of scope
• Formulas
• No implementation for IFRS 2008 taxonomy
• Prototypes in 2008 for cross-context calculations
  and dimensional calculations

16
Visualisation

• Beside providing a stable platform the new
  taxonomy design allows better visualisation
• XBRL Educational Bound Volume for IFRS
• Interactive between XBRL information and
  International Financial Reporting Standards
• Integrated approach of taxonomy viewer and eIFRS
• Human readable XBRL information of taxonomy
  structure

17
Summary

• Timeline alignment with the IASB
• Use of dimensions
• Modelling of tables
• IFRS Taxonomy Architecture discussion paper
• IFRS Taxonomy Prototype
