Extracting REST resource models from procedure-oriented service interfaces

Static Analysis for Improved Modularity of Procedural Web Application Programming Interfaces

“…The only relationship type studied is strict containment by Eshuis and Van Gorp [39]. The work of [15] was one of the first to extract entities from procedural API operation signatures (WSDL based), using a natural language processing technique. Relatively modular operational signatures were used, through which hierarchical relationships between entities were derived, reflecting the hierarchical resource relation-ships encountered in REST APIs.…”

“…Service interface remodularization was first addressed by Athanasopoulos and Kontogiannis [15] and Ouni et al [40], based on structural similarity measures of operations in an interface, e.g., similarity of message types used in operations and input/output dependencies of operations. Both approaches analyse structural similarity of operations based and optimization techniques to reason about operations splitting.…”

“…Both approaches analyse structural similarity of operations based and optimization techniques to reason about operations splitting. Athanasopoulos and Kontogiannis [15] focussed on dependencies within operations, operation cohesion, to iteratively split a service interface using a greedy algorithm. Ouni et al [40] focusses on the operation coupling or dependencies across operations.…”

“…It maps into different languages such as Java, RFC API, PHP (SoapClient). Importantly, previous static API analysis techniques focused on procedural APIs and WSDL specifically (e.g., [15]- [19]). Another reason that our techniques have not supported REST API is that it is not a procedural language, as the data types are reflected through resources.…”
