Restful Services

In the internet environment, web services based on representational state transfer (REST) have become the de facto standard. The addition of semantics is intended to enhance the description of web services with information that enables automatic agents to understand their data. However, the existence of different languages to semantically describe services makes it difficult to discover and select the service that best meets a requirement. Furthermore, relatively few proposals have a RESTful service semantic description, making the discovery process for RESTful services more difficult. This work proposes a RESTful semantic web service discovery architecture based on semantic interfaces (SERIN). SERIN is an ontology with annotations that semantically describe RESTful web services. This architecture enables software agents to automatically discover and make service calls in order to execute a determined task.

This chapter aims to present a general overview of today's dominant software architectural style for developing web services, namely REST, by comparing the core elements of this paradigm with the big web service model. The study evaluates the HTTP requests, responses, and thus, the SOAP/JSON payloads involved in consuming a big web service and a RESTful service that is developed in the ASP.NET Core Web API framework. After summarizing the REST constraints, the chapter elucidates how the example RESTful web service satisfies these constraints and lists some scenarios suited to each paradigm. The study notes the object-oriented elements that are inherent in RESTful services, specifically how polymorphism and abstraction principles can be applied to RESTful services.

Web services are applications that allow for communication between devices over the internet and are independent of the technology. The devices are built and use standardized eXtensible Markup Language (XML) for information exchange. A client or user is able to invoke a web service by sending an XML message and then gets back and XML response message. There are a number of communication protocols for web services that use the XML format such as Web Services Flow Language (WSFL), Blocks Extensible Exchange Protocol(BEEP) etc. Simple Object Access Protocol (SOAP) and Representational State Transfer (REST) are used options for accessing web services. It is not directly comparable that SOAP is a communications protocol while REST is a set of architectural principles for data transmission. In this paper, the data size of 1KB, 2KB, 4KB, 8KB and 16KB were tested each for Audio, Video and result obtained for CRUD methods. The encryption and decryption timings in milliseconds/seconds were recorded by programming extensibility points of a WCF REST web service in the Azure cloud..

The Broker Architecture became popular involving client and server. Representational State Transfer(REST) architecture is the architecture of World Wide Web. REST uses HTTP protocol based on Servlet and ASMX technology is replaced by WCF web service technology. SOAP and REST are two kinds of WCF web services. REST is lightweight compared to SOAP and hence emerged as the popular technology for building distributed applications in the cloud. In this paper, conducted by exposing a HTTP endpoint address, HTTP relay binding (webHttpRelayBinding) and CRUD contract through interface. The interface is decorated using WebGet and WebInvoke attributes. WCF configuration file created using XML tags for use with REST web service.

Web Services have become essential to the software industry as they represent reusable, remotely accessible functionality and data. Since Web Services must be discovered before being consumed, many discovery approaches applying classic Information Retrieval techniques, which store and process textual service descriptions, have arisen. These efforts are affected by term mismatch: a description relevant to a query can be retrieved only if they share many words. We present an approach to improve Web Service discoverability that automatically augments Web Service descriptions and can be used on top of such existing syntactic-based approaches. We exploit Named Entity Recognition to identify entities in descriptions and expand them with information from public text corpora, for example, Wikidata, mitigating term mismatch since it exploits both synonyms and hypernyms. We evaluated our approach together with classical syntactic-based service discovery approaches using a real 1274-service dataset, achieving up to 15.06% better Recall scores, and up to 17% Precision-at-1, 8% Precision-at-2 and 4% Precision-at-3.

Semantic Interoperation

Commercial-off-the-shelf (COTS) Simulation Packages (CSPs) are widely used in industry primarily due to economic factors associated with developing proprietary software platforms. Regardless of their widespread use, CSPs have yet to operate across organizational boundaries. The limited reuse and interoperability of CSPs are affected by the same semantic issues that restrict the inter-organizational use of software components and web services. The current representations of Web components are predominantly syntactic in nature lacking the fundamental semantic underpinning required to support discovery on the emerging Semantic Web. The authors present new research that partially alleviates the problem of limited semantic reuse and interoperability of simulation components in CSPs. Semantic models, in the form of ontologies, utilized by the authors’ Web service discovery and deployment architecture, provide one approach to support simulation model reuse. Semantic interoperation is achieved through a simulation component ontology that is used to identify required components at varying levels of granularity (i.e. including both abstract and specialized components). Selected simulation components are loaded into a CSP, modified according to the requirements of the new model and executed. The research presented here is based on the development of an ontology, connector software, and a Web service discovery architecture. The ontology is extracted from example simulation scenarios involving airport, restaurant and kitchen service suppliers. The ontology engineering framework and discovery architecture provide a novel approach to inter-organizational simulation, by adopting a less intrusive interface between participants Although specific to CSPs this work has wider implications for the simulation community. The reason being that the community as a whole stands to benefit through from an increased awareness of the state-of-the-art in Software Engineering (for example, ontology-supported component discovery and reuse, and service-oriented computing), and it is expected that this will eventually lead to the development of a unique Software Engineering-inspired methodology to build simulations in future.

Purpose Many REpresentational State Transfer (RESTful) Web services suffered from anti-patterns problem, which may diminish the sustainability of the services. The anti-patterns problem could happen in the code of the programme or the uniform resource identifiers (URIs) of RESTful Web services. This study aims to address the problem by proposing a technique and an algorithm for detecting anti-patterns in RESTful Web services. Specifically, the technique is designed based on URIs parsing process. Design/methodology/approach The study was conducted following the design science research process, which has six activities, namely, identifying problems, identifying solutions, design the solutions, demonstrate the solution, evaluation and communicate the solution. The proposed technique was embedded in an algorithm and evaluated in four phases covering the process of extracting the URIs, implementing the anti-pattern detection algorithm, detecting the anti-patterns and validating the results. Findings The results of the study suggested an acceptable level of accuracy for the anti-patterns detection with 82.30% of precision, 87.86% of recall and 84.93% of F-measure. Practical implications The technique and the algorithm can be used by developers of RESTful Web services to detect possible anti-pattern occurrences in the service-based systems. Originality/value The technique is personalised to detect amorphous URI and ambiguous name anti-patterns in which it scans the Web service URIs using specified rules and compares them with pre-determined syntax and corpus.

An algorithm based on information retrieval that applies the lexical database WordNet together with a linear discriminant function is proposed. It calculates the degree of similarity between words and their relative importance to support the development of distributed applications based on web services. The algorithm uses the semantic information contained in the Web Service Description Language specifications and ranks web services based on their similarity to the one the developer is searching for. It is applied to a set of 48 real web services in five categories, then compared them to four other algorithms based on information retrieval, showing an averaged improvement over all data between 0.6% and 1.9% in precision and 0.7% and 3.1% in recall for the top 15 ranked web services. The objective was to reduce the burden and time spent searching web services during the development of distributed applications, and it can be used as an alternative to current web service discovery systems such as brokers in the Universal Description, Discovery, and Integration (UDDI) platform.

Dinas Kependudukan dan Pencatatan Sipil Kota Bogor atau lebih dikenal Disdukcapil Kota Bogor merupakan salah satu instansi pemerintahan yang berada di bidang pelayanan masyarakat yang khususnya dalam bentuk pelayanan Administrasi Kependudukan Kartu Keluarga (KK) dan Kartu Tanda Penduduk (KTP). Kondisi saat ini yang terjadi adalah belum sepenuhnya berjalan dengan baik dan masih ditemuinya hambatan. Proses pembuatan KK dan KTP saat ini dimulai dari masyarakat mengisi formulir biodata yang berada dikelurahan dan memenuhi persyaratan yang ditetapkan. Setelah semua data telah lengkap pemohon diharuskan datang ke Kantor Disdukcapil untuk memproses permohonan cetak KK dan KTP. Waktu proses pembuatan KK adalah 7 hari kerja dan untuk KTP adalah maksimal 14 hari kerja apabila tidak ada kendala dimulai dari tanggal pendaftaran. Setelah tanggal yang ditentukan pemohon datang kembali ke kantor Disdukcapil untuk mengambil produk yang mereka cetak kemarin. Pada penelitian ini memanfaatkan metode Representational State Transfer (RESTFULL) Web Service. RESTFULL web service adalah metode teknologi yang menerapkan konsep perpindahan antar state yang menggunakan browser atau disebut juga mekanisme HTTP untuk menghubungkan aplikasi dengan aplikasi lain. Dalam hal ini metode RESTFULL digunakan sebagai akses data ke Database SIAK yang bertujuan untuk mempermudah prosedur permohonan pendaftaran KK dan KTP dan memberikan informasi yang terbaharui. Berdasarkan hasil pengujian yang telah dilakukan maka dapat disimpulkan bahwa secara fungsional seluruh proses pada sistem registrasi online kependudukan dengan menggunakan metode RESTFULL Web Service telah berjalan sesuai dengan yang diharapkan dan dapat mengurangi masyarakat yang datang langsung ke kantor Disdukcapil untuk melakukan permohonan KK dan KTP serta memberikan informasi yang actual.
