Perhaps you mean the web services as they are described by WSDL, 
i.e., they are more or less objects with public methods exposed 
as operations in WSDL. 

The objective of our research is to automate the service 
composition process. 
That is, a client (may be user or an application) creates 
only a request. Given this request, a process (agent) is 
created that is responsible for the request realization. 
This realization is done by discovering, and then composing 
appropriate services according to *one fixed protocol*. 

You are right, the approach we propose requires a revision 
of the concept of service architecture. 

Best regards,
Stanislaw,
