Software Product Lines (SPL) emerged to promote the strategic, planned reuse that yields predictable results. Aspect Oriented Software Development (AOSD) provides efficient solution for modularity and handling of crosscutting concerns. Recent research proposes use of AOSD in SPL for better separation of concerns and modularity to increase variability that leads to more reusable core assets. This paper highlights the gap in the area of reusability assessment of aspect oriented product line core assets and proposes a reusability assessment framework for aspect oriented product line core assets. ©2009 IEEE.
