The ADAREP documentation for ADAREP 8.3.3 states: "Once the XML document is created, it can be transferred to a Windows or UNIX machine and you can use your own code or other tools to transform it. The XML document is structured as defined by an XML schema definition file (adabas.xsd) provided in the online Community Discussion Forum for Adabas. A stylesheet (adabas.xsl) is also provided for your use at the same location.

A search of the ADABAS Community Discussion Forum turns up nothing. Anyone know where I might find this schema?

You will find it all HERE
