One more key piece is in place for Bayesian modelling with apps: MMDS 1.6.1 just got approved on the AppStore, and brings with it the ability to recognise files with the .bayesian extension (or MIME type chemical/x-bayesian), and import them into the collection of available models that can be used to calculate properties. At the present time the only official way to create such models is to use the bleeding edge build of the Chemical Development Kit and roll your own wrapper code, but we’re working on that!
