• framework and modularization - building a taxonomy from logical pieces

• aim:▫ avoiding redundancy (elements and relationships)▫minimizing of efforts▫minimizing of size▫maximizing of functionality and flexibility

• technical approaches:▫modularization on linkbase (extended links) level [IFRS-GP]▫modularization with one sack for elements definitions [FINREP]▫modularization with common elements' sacks [COREP]▫mix

(extending prohibited)▫additional:

file name context id reported element …

• requirements for data accuracy▫precision/decimals attributes▫depending on concept or data type

• XBRL and other validations

▫ XBRL - embedded in portal validator

▫ need for customization of error messages language human readability

▫ advanced business rules business rules need to be communicated to reporting entities (preferred

electronic format, e.g. CSV, XML, …) available software specific solutions

▫ other checks formal requirements regarding instance documents completeness

▫ historical checks on the database level

• Data conversion▫mapping of:

taxonomies in order to design database reports (instance documents) into databases

▫mechanism to flatten XBRL contextually dimensionally

▫may support problem of versioning indication of changes in taxonomies with regard to databases consequences of taxonomy changes for XBRL instance

• technical (ID) labels▫construction: link:label elements with specific xlink:role

attribute value▫unique identification of a concept▫benefits:

easier and faster communications (short codes instead of long labels)

easier indication of concepts (in taxonomy, instance document or validation reports)

direct link between data model and the taxonomy supports designing of, mappings to and maintenance of

databases supports versioning (codes don't change while names or

namespaces do)

Rules and processes regarding maintenanceRules and processes regarding maintenanceVI

Responsibilities of the reporting banks• gathering and calculation of reporting data• generation of the instance documents▫correct definition of context information▫ability to localise reporting concepts in the taxonomy

structure▫proper mapping from internal systems and databases

• validation of the instance document▫XBRL (XML and others)▫business rules▫ formal requirements

• sending of the instance document to the reporting system• understanding of error reports and correction of errors
