Thomas Klement, XBRL Germany, thomas.klement@xbrl.deHarald Schmitt, IASCF, hschmitt@iasb.org.uk

Agenda• Introduction• Scenario• Domain issues• Technical issues• Mapping and query basics• Evaluation results

Current situation“Gap between financial reporting information and originating data sources”

The reasons are– High degree of aggregation versus bulk data– Complex processing rules – Heterogeneous data models– Various data exchange formats– Few experience with use of standards

Objective• How can standards help bridging the gap?

– Existing XML standards– Upcoming XBRL standards

• What standards are needed?– XBRL import/export– Validity checking– Inter-XBRL mapping– XBRL Transformation– XBRL querying

XBRL Capabilities ─ Scenario: Corporate Group Reporting

XBRL GL

Will XBRL Become an Enabling Technology for Backwards Discovery?

What standards are available?

• XBRL– XBRL FR– Dimensional

Taxonomies– XBRL GL– Formulas– Generic Linkbases

• XML– SQL/XML– XML for Analysis– XPath– XSLT– XQuery

Example:

Storage, Processing and Transition

GL FR FR

ERP XML DB

Main problems

• Cross-system transitions

• Bi-directional mappings

Makes Consolidation Bi-directional Mappings Impossible?

• Individual company closing– Period initialisation– Carry-over– Compilation– Validation– Reconciliation– Allocation– Reclassification– Currency conversion– Validation

• Concolidated financial statement– Changes of consolidation

scope– Elimination of inter-company

profit and loss– Group summation– Reclassification– Consolidation of investments– Validation
