Given we have documented the data model as a key aspect of SOA in the RM, I
think it depends on the "view" of the service. If one views a service as a
gateway to a process, the data likely becomes secondary, if they view it as
a means to generate a specific piece of data, perhaps it takes on higher
importance.
