Security-oriented workflows for the Social Sciences

Abstract

The service-oriented computing paradigm and its application to support e-Infrastructures offers, at least in principle, the opportunity to realise platforms for multi-and inter-disciplinary research. Augmenting the service-oriented model for e-Research are mechanisms for services to be coupled and enacted in a coordinated manner through workflow environments. Typically workflows capture a research process that can be shared and repeated by others. However, existing models of workflow definition and enactment assume that services are directly available and can be accessed and invoked by arbitrary users or enactment engines. In more security-oriented domains, such assumptions rarely hold true...
