The International Conference on Aspect-Oriented Software Development (AOSD) is the premier conference on software modularity, with an emphasis on modular structures that cut across traditional abstraction boundaries. The conference offers several tracks, including the Research and Industry Tracks, which bring together leading researchers and practitioners working in such fields as software engineering, programming languages, systems, and others. AOSD welcomes submissions of high quality in all areas relating to aspects, ranging from foundational research to evaluations of aspect-oriented concepts.
