In line with my previous response, look at the complication of the taxonomy you are considering while you are just thinking out loud! Will it really help to bucket things in this way?
Years ago I became fascinated with what I read on facet classification. Now that I think about it, it is the more general ideas that describe RBAC (role-based) vs. ABAC (attribute-based), i.e. forget about the bins and just describe things. Let the consumer decide which collection of attributes are relevant to the job at hand.

Other potential types of services are Infrastructure Services, Utility Services, Function Services (still fuzzy on the name - meaning fine-grained bits of functionality such as a single calculation), and Presentation Services. Application Services can also cover those types of services that are "in between" Function Services and Process Services - i.e. more coarse-grained than Function Services, but not as complex as Process Services (and also not business process definitions, as Process Services are). An example of an Application Service could be a service that provides a loan amortization schedule for a loan, invoking one or more Function Services for fine-grained units of functionality.

Not types of service providers; service providers that provide certain types of services (e.g. data service provider = service provider of data services).

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.

I think it's a question of service providers, but more specifically of what *types* of services. 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).

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 users of the services 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?

Can we have stakeholders who are providers or maintainers of something other than services? 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?
