Much has been investigated about software reuse since the software crisis. The development of software reuse methods, implementation techniques, and cost models has resulted in a significant amount of research over years. Nevertheless, the increasing adoption of reuse techniques, many of them subsumed under higher level software engineering processes, and advanced programming techniques that ease the way to reuse software assets, have hidden somehow in the recent years new research trends on the practice of reuse and caused the disappearance of several reuse conferences. Also, new forms of reuse like open data and feature models have brought new opportunities for reuse beyond the traditional software components.From past to present, we summarize in this research the recent history of software reuse, and we report new research areas and forms of reuse according to current needs in industry and application domains, as well as promising research trends for the upcoming years.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
