JDE 91 Address Book Canonical Schema

I am building an integrationusing BizTalk 2010 between Siebel 7.8 and both JDE 8.12 and 9.1 Adress Book. The client is going to gradually migrate sites from JDE 8.12 to JDE 9.1. During this migration they are planning a “Big Bang” upgrade of Siebel. Because of this I have chosen to use a canonical messaging pattern to mitigate the impact of the cahnges to the intergration. I am looking for a good canonical for the JDE Adress Book. Has anyone ever used one and where can I find it? Thanks in advance – Greg D.
