11. Risks involved With data in electronic format we need specific controls for:  Identification  Integrity  Authenticity

12. Audit and assurance issues  The current auditing standards are providing no guidance how to provide assurance on information in electronic format  Current audit opinion is focusing on document level (fair view)  Instance document is a dataset, presentation via a style sheet, so no fair view??  So we need assurance on data-level??  We have no taxonomy for the audit opinion or guidance how to connect the opinion to an instance document, could be the FS  No requirements yet for integrity and authenticity of instances documents  No guidance yet about signing audit opinions and validations of the signature

13. Subject matter: Financial Statements In paper format  Identifying data (Entity)  Data  Classification / Grouping  Disclosures  Layout / Presentation  Page numbers  Graphics  -- In XBRL format  Identifying data (Entity)  Data  Tags  Disclosures  --  Taxonomy references  ??
