Meta-applications

A classic application is like a black box of functionality which can be accessed and used by opaque interfaces. What's happening inside the application is not your business, but it guarantees the job will be done. A classic application is building trust by taking care of your data as long as you don't mess with how it's getting done.

In a service oriented world where services are used and reused as building blocks, the black box is gone. A SOA is transparent and built up of composite services. A SOA consists of meta-applications which consists of services. A meta-application is a set of services using the same policies as a trust boundary. With service governance the trust of meta-applications will be as high as for classic applications, or will it not?
