The variety of Machine-to-Machine (M2M) applications based on very heterogeneous forms of platforms, technology, and data models has resulted in vertical solutions where interoperability is very limited. In order to develop horizontal platforms across different business domains, networks and devices, it is necessary to outline generic capabilities. Service Capabilities provide data mediation functions that may be shared by different applications through application programming interfaces. The paper presents an approach to design RESTful Web Services for access to location and presence status information of M2M devices. The Device Reachability Service Capability provides access to device location and allows device presence information to be registered and obtained. Web Service operations are identified by analysis on typical use cases. M2M device reachability information is modelled as REST resources organized in a tree structure. Web Service performance characteristics are evaluated by simulation.

REpresentational State Transfer (REST) is an architectural style that has recently emerged as a new approach to develop and deliver Web services. In fact, a great number of companies, such as eBay™, Twitter™, and Amazon.com™, have adopted REST to deliver Web services and Web feeds. This chapter offers a review of the support for consuming RESTful Web services in Adobe™ Flex™; then, it presents two case studies about the development of third-party RESTful Web services-based Rich Internet Applications (RIAs) using Adobe Flex™ along with HyperText Markup Languages (HTML) and JavaScript. The case studies presented in this chapter are intended to explain the common prerequisites for using RESTful Web services Application Programming Interfaces (APIs) as well as the particular implementation details, including the challenges and alternatives facing the capabilities and limitations of the target technologies. In addition, they exemplify the use of some User Interface (UI) patterns.

Provision Of Services

The appropriate deployment of web service operations at the service provider site plays a critical role in the efficient provision of services to clients. In this paper, the authors assume that a service provider has several servers over which web service operations can be deployed. Given a workflow of web services and the topology of the servers, the most efficient mapping of operations to servers must then be discovered. Efficiency is measured in terms of two cost functions that concern the execution time of the workflow and the fairness of the load distribution among the servers. The authors study different topologies for the workflow structure and the server connectivity and propose a suite of greedy algorithms for each combination.

Restful Services

AbstractModern RESTful services expose RESTful APIs to integrate with diversified applications. Most RESTful API parameters are weakly typed, which greatly increases the possible input value space. This poses difficulties for automated testing tools to generate effective test cases to reveal web service defects related to parameter validation. We call this phenomenon the type collapse problem. To remedy this problem, we introduce FET (Format-encoded Type) techniques, including the FET, the FET lattice, and the FET inference to model fine-grained information for API parameters. Enhanced by FET techniques, automated testing tools can generate targeted test cases. We demonstrate Leif, a trace-driven fuzzing tool, as a proof-of-concept implementation of FET techniques. Experiment results on 27 commercial services show that FET inference precisely captures documented parameter definitions, which helps Leif to discover 11 new bugs and reduce $$72\% \sim 86\%$$ 72 % ∼ 86 % fuzzing time as compared to state-of-the-art fuzzers.

Pengembangan sistem informasi membutuhkan interoperabilitas dalam lingkungan yang heterogen, dilihat dari sistem operasi, perangkat lunak, bahasa pemrograman, dan basis data, sehingga dapat saling berkomunikasi dan bertukar data atau informasi. RESTful web service dapat digunakan sebagai salah satu teknologi untuk mewujudkan interoperabilitas. Sebuah studi kasus tentang aplikasi perpustakaan telah digunakan dalam penelitian ini. Aplikasi tersebut dibangun dengan Slim Framework PHP untuk sisi server dan Visual Basic pada sisi client. Komunikasi antara client dan server menggunakan HTTP method yaitu GET, POST, PUT, dan DELETE. Pengujian telah dilakukan untuk melihat performa dari web service yang telah dikembangkan menggunakan perangkat lunak Postman. Hasil dari penelitian ini menunjukkan bahwa, aplikasi client dapat mengakses web service yang disediakan di sisi server sebagai wujud interoperabilitas.   Information development systems need interoperability in heterogeneous environments, seen from operating systems, software, programming languages, and databases, so that they can communicate and exchange data or information. RESTful web services can be used as one of the technologies to realize interoperability. As case studies build library applications using PHP Slim Framework on the server side, while Visual Basic programming language is used on the client side. Communication Between client and server using HTTP Method that is GET, POST, PUT, and DELETE. Testing has been done to see the performance of web service functionality that has been developed using Postman software. The result shows that client applications can access the web services provided on the server side as a form of interoperability.

Web service substitution is one of the most advanced tasks that a composite Web service developer must achieve. Substitution occurs when, in a composite scenario, a service operation is replaced to improve the composition performance or fix a disruption caused by a failing service. To move the automation of substitution forward, a set of measures, considering structure and functionality of Web services, are provided. Most of current proposals for the discovery and matchmaking of Web services are based on the semantic perspective, which lacks the precise information that is needed toward Web service substitution. This paper describes a set of similarity measures to support this substitution. Similarity measurement accounts the differences or similarities by the syntax comparison of names and data types, followed by the comparison of input and output parameters values of Web service operations. Calculation of these measures was implemented using a filtering process. To evaluate this approach, a software architecture was implemented, and experimental tests were carried on both private and public available Web services. Additionally, as is discussed, the application of these measures can be extended to other Web services tasks, such as classification, clustering and composition.

Web services have been employed in a wide range of applications and have become a key technology in developing business operations on the Web. In order to leverage on the use of Web services, Web service operations such as discovery, composition, and interoperability need to be fully supported. Several approaches have been proposed for each of these operations but these have advantages and disadvantages as well as varying levels of suitability for different applications. This leads to a motivation to explore and to compare current approaches as well as to highlight problems of the operations and their possible solutions. In this chapter, an introduction, a brief survey, problems and possible solutions to the three Web service operations mentioned above are discussed. The research opportunities and possible future directions on Web service are also presented.

Concept Profile Analysis

The Concept Profile Analysis technology (overlapping co-occurring concept sets based on knowledge contained in biomedical abstracts) has led to new biomedical discoveries, and users have been able to interact with concept profiles through the interactive tool “Anni” (http://biosemantics.org/anni). However, Anni provides no way for users to save their procedures, results, or related provenance. Here we present a new suite of Web Service operations that allows bioinformaticians to design and execute their own Concept Profile Analysis workflow, possibly as part of a larger bioinformatics analysis. The source code can be downloaded from ZENODO at http://www.dx.doi.org/10.5281/zenodo.10963.
