Due various reason (e.g. updates) we need to seperate our application from the data in two installation packages - e.g. like a eBook-reader application.

Which is the best concept to prepare/combine these sis installation packages, for the one package installation system needed in Ovi?

Currently our data sis package are created as SISPATCH, like a level-addon for a game. We can't add a embedded sis line to our data because of the depencies tested before the embedded sis will installed.

To include the data in the application package is not a solution (because of the exclusion installation)
