strategy: Internet: impact on B2C and B2B -- intranet: impact of application integration (EAI)
motivation: some particular functionality can be exposed via web
motivation: let's structure content in XML: now machines can process it
procedure: actual operation: SOAP + HTTP, XML RPC, REST etc.
definition: application that is identified by URI and whose interfaces are defined/described/discoverable as XML
procedure: service description (publish): WSDL
procedure: service detection (find): UDDI , broker negotiation

Comment:: note: content that is exchanged can but doesn't have to be XML
