  The area of service oriented computing stretches between two
  extremes: On the one hand industry has pushed  a whole stack of
  {WS-*} standards and tools to support the integration of distributed
  services into business applications. These standards are used in
  production environments and are applied successfully, e.g. in the
  area of enterprise application integration.
  However, the
   expensive and labor intensive task of putting together
  services and maintaining and administering the composed applications
   has  to be done manually. 
   In contrast, academia is busily working on numerous efforts leveraging
  ontology based semantics and various AI planning techniques to
  automate these tasks. Yet, up to now the developed technologies have
  rarely if ever been applied in industry. 
  In our opinion, this has
  two main reasons:   there is high cost involved in creating the
  necessary comprehensive ontologies and  businesses are reluctant to
  trust  semantic technologies. In this paper we  bring together the
  extremes in order to combine their strengths. We show how to
  flexibly integrate advanced semantic service discovery, composition
  and invocation technology into manually created standard {BPEL}
  processes. Our approach leaves it to the discretion of the developer
  to flexibly choose an appropriate degree of automation for the
  process at hand and thus offers him complete control over the usage
  of semantic technology.
