Pro’s:• Political issues like reducing administrative burden
• Commitment towards European COREP and FINREP models
• To be prepared for the future
Con’s:• Existing e-Line functionalities versus XBRL capabilities
• Most Dutch banks show restraint when it comes to using XBRL
Resulting in: • Use international taxonomies when available and build national

• Support XBRL as additional import format

alternative structures like e-Line schema’s?
Some Considerations:• Business specifies reporting models in Excel
• Models are translated into XML Blueprints
• Taxonomies (COREP / FINREP) are a given
• Mapping data between systems not new for DNB
• A generic mapping solution
• ...
