As you've said, CatWalk is so tightly coupled with SO that a *extensible* replacement is needed. > > I guess, if we wanted an admin tool that works with several ORMs > we'd have to > define yet another data access layer/api that defines a subset of > the features > (i.e column types, query methods, getters/setters) in all supported > ORMs. I've been playing with a skeleton of this using generic functions, both to create widgets for complete objects or it's attributes (mapped columns, joins, etc). The idea is that the if the widget creating generic function doesn't know how to handle a given object, it will try to automatically create a widget based on it's attributes. This should allow for easy extensibility of the "admin" interface.

That's very cool! :) Maybe you'd like to contribute or be a father to FastData v2? If so then the trunk ML is probably the best place to discuss it.
