Richard, Burn... thanks for the replies. I'll try the -D option which appears to be just what I wanted. Prior to the replies, I had done what Richard also suggested and intercepted the file input stream, modified the XML descriptor and then sent it on parseResourceSpecifier. I had also tried using uimafit, but it looked like ConceptMapper doesn't implement what uimafit needs. Thanks / Dan
