We have a research project called Clio, that deals with precisely this
problem. It is a joint project between University of Toronto and IBM
Almaden. We have a number of papers on this subject (called "schema
mapping"). You can find them, and also more info on the project at

http://www.cs.toronto.edu/db/clio/

Also, is there any possibility that you share some examples of the
source and target schemas you were trying to map? We would be very
interested in applying our tool to examples from people who have already
faced the problem of schema mapping.

Let me know if you need any additional information,
