Question-Direct Mapping tool

Bonjour, 

I need a direct mapping implementation/a tool which supports Direct Mapping and can translate many-to-many join relation into simple triples (although it is not part of the W3C Direct Mapping). Is there any direct mapping implementation that can do this? What I need is translation of many-to-many relation to simple triples without using R2RML-Compliant tools. 

After searching for RDB to RDF tools that are reported by RDB2RDF Implementation Report. I see a list of DM processors that implement the Direct Mapping and then the results of the Direct Mapping implementation test. However, these tests for example (DirectGraphTC0011) are done on the direct mapping intial expected output. 

Thank you for your answer, 
Best Regards, 
Sara
