Shweta Gupta, IRIS Chair Reporting Taxonomy Architecture Processes Practice Working Group

1. 21th XBRL International Conference Taxonomy Architecture Practice Working Group (TAPWG) October 19, 2010 Beijing, China Shweta Gupta, IRIS Chair Reporting Taxonomy Architecture Processes Practice Working Group

2. Topics for today • Part 1 –TAPWG Overview • Part 2 – Mission of TAPWG • Part 3 – Past Deliverables • Part 4 – Future Plans

3. TAPWG Overview • The purpose of the Taxonomy Architecture (TA) Practice Working Group is to: • Improve quality and lower costs associated with the business value of XBRL projects by providing detailed analysis (provide output --- interest of business users) of domain, logical and physical models of taxonomies and objectively evaluating their impact on the reusability of their content. • Establish Taxonomy Implementation Best Practices • Examples are: • Identification of the parties sharing and consuming XBRL information • Tracking of official and extension taxonomies, instances, and other files • Security, authentication and integrity, transport and handling, validation, etc.

4. TAPWG Overview (cont.) • Specific Topics addressed: • Alternative logical modeling of otherwise identical domain content, including dimensions, tables, tuples, and other constructs • Interoperability of instances • Usability of data for analytic comparability, especially for financial fundamentals, including linking of distinct taxonomies • Style Guides • Impact of new XBRL Specifications

5. TAPWG Overview (cont.) • Specific Topics addressed: • Displaying Taxonomies with Matrix structures • Examples are: • Identification of the parties sharing and consuming XBRL information • Tracking of official and extension taxonomies, instances, and other files • Security, authentication and integrity, transport and handling, validation, etc. • Request for Comment (RFC) • Authorized output from BPB working groups • Formal communication from BPB to marketplace • When vetted through marketplace becomes a “Practice Note”

6. Taxonomy Scope • Taxonomies standardize data in Business Reporting Supply Chain (BRSC) Business Operations Internal Business Reporting External Business Reporting Investment, Lending, Regulation Economic Policymaking Processes Taxonomies Companies Business Publishers and Data Aggregators Investors Central Banks Participants Trading Partners Management Accountants Internal Auditors External Auditors Regulators and Administrators Software Vendors and Service Providers

7. External Reporting Eco System Collect Define Create Disseminate Aggregate/Production Review Regulator/Standard Setter Preparer Auditor/Creator Base Taxonomy Extension Taxonomy Regulator Data Aggregator Regulator Data Aggregator Investors/Analysts V V V V V = Validate V

8. Typical Taxonomy Structures Reporting entity extensions (Banks, Companies, Mutual Funds, Govt. Agencies) Extension Taxonomies Regulators/Standard Setters/Data Aggregators Regulators Base Taxonomies Standard Setters

9. TAPWG • Membership of WG • Comprised of over 20 individuals from diverse backgrounds • Means of communication • WG meets once a week via telecom • Meets face-to-face adjacent to XBRL conferences • Diversity of member profiles • TAPWG members have experience in large scale taxonomy development projects • Most also have experience in domain expertise • Will poised to face future demands

10. TAPWG Activities • Build out Business Reporting Proposition Document • Created a Business Reporting Logical Model • Creation of a FRTA 1.5

11. Business Reporting Proposition Document • The TAPWG developed a Business Reporting Proposition Document to explain the use case of having a Business Reporting Model

12. Business Reporting Logical Model • A model which explicitly states the semantics of business reporting. • A best practices specification for implementing the explicit business reporting semantics of a defined model within the XBRL syntax. • A framework for implementation of a financial reporting logical model. • A framework reusable by additional business areas, other than financial reporting. • Modeled in UML • A set of ‘measures’ used by financial reporting within the business reporting framework.

13. Business Reporting Logical Model • Status: Internal Working Draft • Refinements Suggested: • Creation of a UML Logical Model • Inclusion of Data Structures across the globe, catering to various Business Reporting Patterns • Confluence with XSB’s Abstract Model initiative

14. FRTA 1.5 • The TAPWG Decided to break the WG to create a short term solution for FRTA revision need • Identifying the rules that have been obsolete, and the TRTF makes exemptions to them. • Revisit the RFCs in January • Include a list of the new points from the FRTA- Way Ahead document initially built • Classify FRTA rules into two documents, one for domain audience and one of technical audience

15. FRTA 1.5 – An update till now * The TA is also discussing if rules pertaining to dimensions can be included in FRTA 1.5

16. TAPWG Confluence with XSB Initiative

17. Summary (Future – What’s next) • How can the TAPWG expand collaboration between countries? • How do we spearhead the updating of FRTA? • TAPWG is looking for new ideas and collaborators? • How does the TAPWG help get companies excited about moving towards a common taxonomy environment using XBRL
