FiVO

FiVO - Grid Virtual Organisation Semantic Framework

The major issues addressed by FiVO framework in the GREDIA project include:

• Provision of a unified semantic inteface (at least at the service level) for discovery and management of all aspects of a Virtual Organization (including its members, agreements, resources, goals, ...)
• Oriented strictly towards Service Oriented Architectures and Grid computing, thus assuming certain requirements on the infrastructures of organizations willing to participate in Virtual Organizations created on the GREDIA platform
• Allowing both static (manual) and dynamic (semi-automatic) creation and deployment of Virtual Organizations aiming to pursue some goal
• Support legacy information systems by mediatng semantic queries into proper standards in which these systems are implemented

In overall the FiVO framework servers as a distributed system for negotiation, creating and managing resources and services within Virtual Organizations spanning heterogeneous real organizations. This is depicted in a sample deployment of FiVO framework within the GREDIA system in below.

The architecture of a single FiVO component is presented in figure below. The basic assumptions are to enable each organization to deploy an instance of FiVO which will enable this organization to participate in GREDIA based Virtual Organizations.
