Why Develop a Corporate Permanent Data Taxonomy for Belgium? Date: 5 December 2007 Joep van Amelsfort

Vancouver December,2007

How can we easily exchange permanent data of one or more corporations between various programs and companies/institutions? Solution Create a XBRL taxonomy for this special purpose. This taxonomy can be based on the “Belgian GAAP” taxonomy as this already describes a big part of the necessary elements.

Development of a taxonomy for the exchange of "permanent" data of Belgian enterprises (and institutions) between various software programs and the Crossroads Bank for Enterprises (CBE).

 Time registration program  Customer management program  Crossroads Bank for Enterprises (CBE)  Accounting program  Annual accounts program  Tax programs  Etc.

1. Inventory of the current databases Inventory of (commercial) database programs and the database of CBE We have used databases from Crossroads Bank for Enterprises, a CRM program called Admin-IS & a accounts production package CaseWare WinAcc 2. Comparison of all these databases Compare all elements from the different databases 3. Synchronise the databases and describe all elements in a taxonomy This taxonomy can be based on BE_FR_PFS_CI

 We have used an spreadsheet to do the first comparison between the 3 databases  NBB has used an another spreadsheet to generate ASCII files that can be imported in the Fujitsu Taxonomy Editor as this was best practice of NBB (National Bank of Belgium) A spreadsheet is a more known tool so you can easily make the first steps.  The final make up of the Taxonomy has been done with the free Fujitsu Taxonomy Editor

 We have found that it is quite time consuming to create a taxonomy More than one we have discussed for more than on hour about a single element  Starting with a special Taxonomy tool is sometimes not advisable, especially if you do not have the scills and experience with this tool Our best practice is to start with a speadsheet and at the end transfer the data to a specialized tool.

 Some XBRL experience in the working group is advisable. XBRL taxonomy generation is not a simple job  Think about the XBRL architecture before you start. With the CPD we would like to integrate with other existing taxonomies, but this requires that you think about the architecture.
