Cannonical data model implementation for Oracle SOA and OSB(Oracle Service Bus)

if you are going to use OSB and OSAO, two suggestions:

1. Reuse of Schema accross OSB and SOA
2. Establishing Cannonical Data Model for reuse

The two possibility :

1. OSB XSD definetions used by both OSB and SOA
2. MDS for maintaining schemas

I Would prefer earlier one and it can be shared widely due to access over HTTP
