Can Specifications reside in the App Layer? Can a Build To Order Spec Produce a Domain Object?

Hi All,

1) Can Specifications (external) reside in the App Layer?

Eg. My Application (Loans) in the app layer needs to call many validations which reside in the other domains. We call these services exposed by other domains (like security) etc via Adapters, but the loans Application object looks ugly since the various method calls are encompassed in it.

Is it advisable to create a separate External Specification Object and in turn that object talk to the various adapters which in turn talk to the External Services.

2) Can a Build To Order Spec Produce an Domain Object?

Currently we pass a build to order spec to a factory to produce a Domain Object, Can the Build To Order Spec itself Produce a Domain Object, thus avoiding the use of a factory?

Thanks & Regards

Ashley
