“…We consider giving a visual representation of RESTful conversations an important first step toward understanding and improving how RESTful APIs are designed, documented, and used. This has motivated our work on extending the standard BPMN Choreography diagrams to create RESTalk, which has a domain-specific focus on the facets of RESTful APIs, e.g., hyperlink flow, requestresponse sequencing [33].…”

“…The design of modeling notations also needs frequent iteration, driven by user feedback. Therefore, after the initial informal feedback during the European Conference on Software Architecture (ECSA 2015) [33], we have decided to conduct an exploratory survey, as part of our strategy for gradual improvement of RESTalk. The survey was conducted among both designers of RESTful APIs and developers of client applications consuming them.…”

“…BPMN has become an ISO standard in 2013 (ISO/IEC 19510). In [33] we have extended the BPMN Choreography diagrams to emphasize relevant details for using the HTTP protocol, such as hypermedia controls [3], headers, and status codes. 6 These are all important for defining the salient properties of the set of request-response messages composing a RESTful conversation.…”

The cost savings introduced by Web services through code reuse and integration opportunities have motivated many businesses to develop Web APIs, with ever increasing numbers opting for the REST architectural style. RESTful Web APIs are decomposed in multiple resources, which the client can manipulate through HTTP interactions with well-defined semantics. Getting the resource in the desired state might require multiple client-server interactions, what we define as a RESTful conversation. RESTful conversations are dynamically guided by hypermedia controls, such as links. Thus, when deciding whether and how to use a given RESTful service, the client might not be aware of all the interactions which are necessary to achieve its goal. This is because existing documentation of RESTful APIs describes the static structure of the interface, exposing lowlevel HTTP details, while little attention has been paid to conceptual, high-level, modeling of the dynamics of RESTful conversations. Low-level HTTP details can be abstracted from during the design phase of the API, or when deciding which API to use. We argue that, in these situations, visual models of the required client-server interactions might increase developers' efficiency and facilitate their understanding. Thus, to capture all possible interaction sequences in a given RESTful conversation, we propose RESTalk, an extension to the BPMN Choreography diagrams to render them more concise and yet sufficiently expressive in the specific REST domain. We also report on the results obtained from an exploratory survey we have conducted to assess the Communicated by Prof.

“…The necessity of conceptual modelling of interactions has resulted in different modelling language proposals such as Business Process Model and Notation (BPMN) [8], Web Services Business Process Execution Language (WS-BPEL) [2], Web Services Choreography Description Language (WS-CDL) [1]. More recently, choreography diagrams were included in BPMN 2.0 [8], and have been used for modelling RESTful services interactions in [9]. [10] uses RESTful services in the cloud to increase reliability, while [11] studies fault tolerance.…”

The service choreography approach has been proposed for describing the global ordering constraints on the observable message exchanges between participant services in service oriented architectures. Recent work advocates the use of structured natural language, in the form of Semantics of Business Vocabulary and Rules (SBVR), for specifying and validating choreographies. This paper addresses the verification of choreographies-whether the local behaviours of the individual participants conform to the global protocol prescribed by the choreography. We describe how declarative specifications of service choreographies can be verified using a trace-based model, namely an adaptation of Shields' vector languages. We also use the so-called blackboard rules, which draw upon the Bach coordination language, as a middleware that adds reactiveness to this declarative setting. Vector languages are to trace languages what matrices are to linear transformations; they afford a more concrete representation which has advantages when it comes to computation or manipulation.
