Ah, it's the other way round - the extension needs to tell the mimetype to oC Web because we are only creating a new file?

No, it's updating an existing file

Why do we need this? Can't the extension just use resource.mimeType directly?

I would like to keep the api surface minimal

Open for suggestions regarding the approach. We could check the resource.mimeType (for jpeg/png), but then it's an implicat thing happening in the AppWrapper rathern than the application announcing what it wants to do (albeit the naming/API isn't ideal yet)

@dschmidt do you have a better suggestion with regards to API design? Or @JammingBen maybe?

[JammingBen]

Hmmm, I can't really think of a non-ugly solution here. You could give apps the possibility to define a custom save task and call that if given. Though it would be a lot of code duplication in this specific case... so I guess I'm fine with this approach. Maybe add a comment to the AppWrapper property to explain how this is used?
