2. www.corep.info Why preparing own mapper tools? The COREP taxonomies contain functionality that is new in XBRL and is being included in the specification, i. e. dimensions. Commercial tools that are able to create xbrl instance documents are being upgraded to support dimensions. Our tools are an example of how easy it is. To test the COREP taxonomies tools are needed when creating XBRL instance documents on basis of the COREP templates.

3. www.corep.info Test case creation coreptest.xlt file is used to fill in test data inside the COREP templates on basis of Excel tables. Each user can prepare as many templates as he needs to build up a complete test case. Data can be used for analyses without reference to a special bank or test unit, because the spreadsheet has an anonymous ID. Fernando Wagener (NCB ES)

4. www.corep.info XBRL instance creation: Preparations To enable the transformation of the Excel test file the formats and all additional sheets have to be removed by running a macro. The file has to be saved on the hard drive. The new created excel file can be uploaded to the mapper application.

5. www.corep.info XBRL instance creation: Architecture Java based web: standard technology. Uses only free available open source packages. Application can be run on an open source web server called Apache Tomcat. XBRL validation will be included in following phases.
