| Abstract | Web services need to continuously adapt to an ever-changing environment. Therefore, over time, web services evolve. A particular part of web service evolution is Web API evolution, concerning any evolutionary steps happening on the level of a particular API type. Web APIs can be classified into three types: remote procedure calls, message-based and resource-based. In the proposed guided research, we want to investigate differences in the propagation of changes in the individual API types. We will instantiate our approach using Apodini, a domain-specific language to write web services in an abstract and generalized manner that is independent of the concrete instantiation of an API type. Our findings are integrated into ApodiniMigrator, a tool-suite for automated, machine-readable migration guides. The system is validated using replications of common web APIs and applying real-world evolutionary steps from the past to assess the system’s capabilities. |
