XBRL 2.1 Specification

• “Segment is used to specify some component of the business entity. Scenario is used to document the circumstances surrounding the measurement of a set of facts, and like the segment element, its content will be application specific.“

Taxonomy Development

• Taxonomy working group:“ We need standardized fact semantics AND tool support.“

• Required kinds of measurement in scenario– actual– restated– adjusted– budgeted– forecasted

• Reasons are– avoidance of duplicates in XBRL databases and other data models– comparability– ability to use facts for analysis purposes

Thomas Klement, XBRL Germany 5th October 20067

Bundesanzeiger

• Processing of instances according to– German AP– IFRS– US GAAP

without extensions• Bundesanzeiger: “We need more fact semantics and a better

description for visualization.“• Requirements

– detection of relevant information for further plausibility checks etc.– multilingual presentation

Thomas Klement, XBRL Germany 5th October 20068

Proposal

• Hybrid solution– XBRL 2.1 compliant– Optional dimensional taxonomy

• explicit dimensions with multilingual-translations

• Best Practice (FRIS) versus GCD

“Small enhancement, high impact“
