Architecture of the COREP-XBRL mapper

Java based web application Uses only open source packages of Java

+ struts.jar for the GUI+ poi.jar for the reading of excel+ jdom.jar for the building of xml+ xml jar files for the xml schema validation (xalan.jar, xerces.jar)+ tomcat server to run the application

How the XBRL-COREP Mapper works I

the application provides the possiblity to upload the coreptest files (formats and descripting sheets must be removed by running an integrated excel macro) a java representation of the excel file

is built by using the poi functionality the object contains sheet, row and cell

object for each corept template the rows are

read and transformed into a partial jdom (xml) tree

How the XBRL-COREP Mapper works II

all partial xml trees are added to the xbrl root element „XBRL“

the complete jdom document is checked to be: wellformed valid according the xml schema rules

the xml output is sent with the response to a new window of the browser

the file can be saved to the file system
