The Semantic Model Extension capabilities in FDI are fine for some very basic and limited edits/customizations. By comparison to the WSM in OAC it is tedious, at best, with wizards and not being able to see much of anything. We would like to have the full Web Semantic Model, integrated with GitHub, with SMML and json available, exactly as in OAC. We hope that this state of the tool is temporary and it will evolve into the full scale capabilities of OAC's WSM.
