Theme 1: Linguistic Primitives Print

The first theme deals with language primitives for services and their interactions that are developed on two different abstraction levels, an architectural design level and a programming abstraction level for service computing. Ontologies and a categorical approach are used to develop a declarative modelling language for services whereas process calculi will provide the adequate programming-level primitives. UML extensions are developed to provide visual representation of the declarative modelling primitives. These theme 1 research activities are broken down into three work packages.

  • WP1 - Modelling in Service-Oriented Architectures - focus on foundations for service description, interaction and composition, at the level of architectural specification.
  • WP2 - Core - focus on the development of core calculi for service-oriented computing, accounting for different interaction and composition architectures, like message-driven or data-driven.
  • WP5 - Combining services - is to extend the core calculi developed in WP2 and to establish a solid mathematical basis for quality of service, service level agreements, workflow-like transactions with compensation, and dynamic reconfiguration.
