Hi,
I'm not sure exactly what the intention is, and I've not looked into the details of the failure. My naive assumption at this point is that the transformation "mostly works" (From RSA to Papyrus-RT Neon), except for the references to the Viewpoint prototypes (Which, I believe, break very early and very badly, probably preventing the rest of the transformation from even starting)
So we could simply replace the broken references, then let run the RSA to Papyrus/RT transformation as-is (Targetting Mars or Neon format), then rely on existing reconcilers to transform the individual diagrams from Mars/Neon to Oxygen (As we did for the Mars -> Neon transition)
Since I'm still not too sure about the changes which occurred this year, there could be more issues. But fixing the broken viewpoint references is a mandatory first step anyway (I don't know if it also requires fixing in Papyrus, if there are viewpoint-based diagrams handled by the Papyrus transformation)
