CHOReOS Governance V&V policies and rules (D4.1)

Abstract : This document presents an initial view of the framework under development for CHOReOS governance and V&V. The focus is on specifying policies and rules on which the framework will rely. After discussing the ULS-FI challenges which are more strictly related to WP 4 goals, we overview the preliminary architecture which will support governance and V&V. We classify policies supporting governance, and start discussing more relevant ones, concerning choreography roles and life-cycle. We also propose approaches for modeling and handling SLA-related requirements. We devote special attention to V&V-related governance aspects, and identify some policies to govern online testing, service ranking and scalability. The framework is still preliminary, in that governance is a transversal concern, and it certainly needs to be harmonized with the components and processes undergoing parallel investigation in the other CHOReOS WPs.
