A survey on service composition languages

In recent years, service-oriented architecture (SOA) has been adopted by industry in developing enterprise systems. Web service composition has been one of the challenging topics in SOA. Numerous approaches have been proposed to tackle this problem. In industry big companies such as Amazon, Netflix, and Uber have developed their own web service composition languages and tools. In academia, on the other hand, there have also been attempts to resolve some of the complexities in web service composition. In this survey we identify and evaluate current prominent service composition languages, and discuss our key findings. After a scan of dozens of service composition systems, 14 systems that used a language-based approach were included in this study. We believe that our findings will help people from industry and academia to learn about some of the major active composition languages and get an overall idea about their commonalities and differences
