Tying XBRL GL to FR: XBRL mappings, transformations and queries across the reporting supply chainThomas 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

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

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
