Ron, This kind of chaining of HelperContexts is one of the things being planned for SDO 3.
In the meantime, I think you could accomplish it, in a very EMF-specific way, by doing something like this: HelperContext parentHelperContext = SDOUtil.createHelperContext(); HelperContext childHelperContext = new HelperContextImpl( ((HelperContextImpl)parentHelperContext).getExtendedMetaData(), false); I'm not sure, but I think that would do what you want, but be warned that all the EMF-specific parts of Tuscany are considered internal and subject to change in future releases.
