An information converter includes: an input for receiving non-structured information transformation specification and a processor. The processor is adapted to (i) convert the non-structured information transformation specification to a structured information transformation specification; (ii) generate information transformation code responsive to the structured information transformation specification; and (iii) associate a code alteration indication to the non-structured information transformation specification in response to an alteration of the information transformation code. A method and a computer readable medium converts the non-structured information transformation specification to a structured information transformation specification; generates information transformation code responsive to the structured information transformation specification, and associates a code alteration indication to the non-structured information transformation specification in response to an alteration of the information transformation code.
