Providing powerful and fine-grained capabilities for the analysis and management of non-functional properties is a major challenge for component-based software systems. In this paper, we propose integration patterns for non- functional properties of hierarchical software components. These patterns are based on a classification of low-level non-functional properties, which takes into account their nature and lifecycle. They make explicit the implementa- tion of these properties in relation with components and can be used to develop some forms of compositional reasoning. The proposals are exploited in non-functional contract ne- gotiation by enabling a negotiation process to be precisely propagated down the component hierarchy.
