| My question still holds: do I really care what type of service as long as I can assess the appropriateness of the real world effects.
The idea of "certain types of service" gets into the FEA endless cycle of are you type A or type B when you're really some of each, what if you support multiple lines of business, ...
Sometimes associating something with categories helps but that is part of description. A rigid assignment of types calcifies the way you look at the world.
Sorry for the diversion to commingled thoughts.

Joe,
But I'm not sure "types" of service providers is relevant. I look at a service description, decide if the real world effects are what I want (and whether the rest of the execution context stuff can be aligned), and then I proceed with the interaction. If I ask for information, I don't know (unless I have a business reason for this to be part of my rationale for which service to use) if it is "data" from a database, results from a simulation, or Mechanical Turk.

So there can be data service providers, perhaps process service providers (e.g. BPEL-based processes), and perhaps even application service providers in a different sense than the traditional ASP (perhaps service-based applications). Joe Michael,
My question is whether there are providers in the SOA sense for something other than services. For example, one could say there are data providers but wouldn't they have their data sources accessed using services? Does that apply to all providing stakeholders?

Aren't manufacturers of equipment stakeholders?
Is the government that collects a tax or regulates a stakeholder?
Aren't the "victims" we discussed at the F2F stakeholders as well?

Or, do we assume by the nature of SOA that if you provide something other than a service, that something is a capability that must have a service access, so you always end up a service provider?
