IFRS Taxonomy Architecture

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

IFRS Taxonomy Architecture

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”}

IFRS Taxonomy Architecture

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

IFRS Taxonomy Architecture

Reference LinkbaseReference 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.

IFRS Taxonomy Architecture

Reference Linkbase

Reference part Use

IssueDate Issue date of the standard or interpretation

Name {IFRS|IAS|IFRIC|SIC|XBRL}

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

IFRS Taxonomy Architecture

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

IFRS Taxonomy Architecture

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

New XBRL Technologies

VersioningVersioning solution as additional information for the IFRS 2008 taxonomy

RenderingTabular rendering in presentation linkbase

Instance rendering out of scope

FormulasNo implementation for IFRS 2008 taxonomy

Prototypes in 2008 for cross-context calculations and dimensional calculations

IFRS Taxonomy Architecture

Visualisation

Beside providing a stable platform the new taxonomy design allows better visualisation

XBRL Educational Bound Volume for IFRSInteractive between XBRL information and International Financial Reporting Standards

Integrated approach of taxonomy viewer and eIFRS

Human readable XBRL information of taxonomy structure
