2. WP Objectives Establish standard structures, taxonomy, etc. for expressing functional and non-functional requirements of a federated cloud infrastructure. Specific goals Collaboration between all partners to build on flagship definitions and requirements analysis. Agree scope of operational policies within a federated environment. Provide structure for statements of requirements to be used in WP7. 2
