| Resumo: | Web services are software accessible via the Internet that provide functionality
to be used by applications. Today, it is natural to reuse third-party
services to compose new services. This process of composition can occur in
two styles, called orchestration and choreography. A choreography represents
a collaboration between services which know their partners in the composition,
to achieve the service s desired functionality. On the other hand, an
orchestration have a central process (the orchestrator) that coordinates all
application operations. Our work is placed in this latter context, by proposing
an abstract model for running service orchestrations. For this purpose,
a graph reduction machine will be defined for the implementation of service
orchestrations specified in a variant of the PEWS composition language.
Moreover, a prototype of this machine (in Java) is built as a proof of concept |
