Some comments: 1. The IDs in JUMP were really intended to be for internal system use only, in order to give Features a unique identity. This capability is currently barely used (which is a good thing!), but I think it should be preserved as is (since this is the more memory, design and processing efficient way of assigning IDs).
If you need a different kind of ID, just add another attribute to your FeatureSchema. 2&3. This is already really supported (at least for POJOs). What isn't supported is describing the resulting object model in the FeatureSchema model. Some extension here might be good (at the risk of making things more complex). I think the deegree Feature model might do this. 4. I am *really* not in favour of this concept. Once you throw away the schema, you don't have much left in a Feature. Java already has a "typeless variable-length container" - it's called a List. If you are finding it painful to migrate data between FeatureSchemas, you can always write some helper methods. Or dump your data into a List and move it that way.
