  • Currently, computer science is in the next period of abstraction.
  • A generation ago we learnt to abstract from hardware and currently we learn to abstract from software in terms of SERVICE oriented architectures (SOA).
  • It is the service that counts for a customer and not the specific software or hardware that is used to implement the service.
  • In a later stage, we may even talk in terms of problem-oriented architectures (or more positively expressed in terms of problem solving oriented architectures) because SOAs are biased towards the service provider and not towards the customer that has a problem that needs to be solved.
  • Service-oriented architectures will become quickly the leading software paradigm.
  • However, SOAs will not scale without signification mechanization of – service discovery, service adaptation, negotiation, service composition, service invocation, and service monitoring; and data and process mediation.
  • Therefore, machine processable semantics needs to be added to bring SOAs to their full potential.
  • Development of open standards (languages) and open source architectures and tools that add semantics to service descriptions
