With Service Oriented Computing (SOC), services have a central rolein rapid development and deployment of loosely-coupled, massivelydistributed scientific applications with supporting services spanningfrom Computer Algebra Systems (CAS) to Grid services. Key featuresfrom service orientation can be easily integrated in a SOC-based development. The integration of SOA with Grid infrastructures and Grid Servicesis an open issue for current research. A service-oriented architecturefor the Grid (like OGSA) and its corresponding infrastructure, namelyOGSI, are fundamental in order to develop Service Orientation overa Grid infrastructure. The PEGAF project is developing a generic platformfor the modeling, implementation and execution of workflow-based applicationwith Grid orientation. In this paper we are presenting the generalarchitecture of the PEGAF platform, and an ontology-oriented viewas the core of a flexible architecture for the definition and executionof dynamic workflows.
