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
