For the last few years, model-driven architecture, aspect-oriented software development and Web service engineering have become widely accepted alternatives for tackling the design and building of complex distributed applications; however, each of them addresses the principle of separation of concerns from their own perspective. When combined appropriately, both model-driven and aspect-oriented software development complement each other to develop high-quality Web service-based systems, maintaining non-functional properties separate from models to code. This chapter provides a methodology that integrates non-functional properties into Web service model-driven development, increasing the systems’ modularity and thus reducing implementation and maintenance costs.

Resumen Los Servicios Web Semánticos ofrecen beneficios, que coadyuvan a la evolución de la Web, como el descubrimiento, invocación y composición dinámica y automática de recursos, habilitan efectivamente la interoperabilidad entre sistemas, permitiendo una amplia gama de nuevos servicios y oportunidades de negocios en la Internet. La estructura necesaria para proveer estos beneficios, hace que su desarrollo sea un proceso complejo, requiriendo establecer formas más fáciles y dinámicas que garanticen reutilización, calidad y rapidez. El desarrollo dirigido por modelos realiza una contribución eficiente en estos aspectos, dado que trabaja de manera intrínseca conceptos como separación de conceptos, reusabilidad e interoperabilidad entre componentes. En este artículo se presenta un enfoque para desarrollo de software dirigido por modelos, orientado al desarrollo de los servicios web semánticos, donde inicialmente se plantean las fases correspondientes al análisis, diseño y desarrollo dentro de la metodología propuesta, aplicando la metodología sobre un pequeño caso de estudio y obtener como resultado la estructura de un Servicio web semántico. Palabras Clave: Servicios web semánticos, Desarrollo dirigido por modelos, ontologías web.   Abstract Semantic Web Services offers benefits that contribute to Web evolution. Benefits such as automatic discovery and invocation, and dynamic composition, effectively enables systems interoperability, allowing a wide range of services and Internet businesses. The necessary structure to provide those benefits by Semantic Web Services makes its development a complex process. It necessary to establish more easy and dynamic ways to develop this kind of software, in order to assure reuse, quality and speediness in the development process. The model-driven software development makes an efficient contribution in those aspect, because it works intrinsically concepts related such separation of concerns, reusability and components interoperability. In this paper we present an approach to model-driven development software applied to Semantic Web Services. First, we establish the phases corresponding to the analysis, design and development in the proposal methodology, by applying it to a case of study we obtain the structure of a Semantic Web Services. Keywords: Semantic Web Services, Model-Driven Development, Web Ontologies.

Service-Oriented Architectures (SOA) are widely used by companies to gain flexibility. Web services are the fitted technical solution used to support SOA by providing interoperability and loose coupling. Basic Web services are being assembled to composite Web services in order to directly support business processes. However, there is much to be done to obtain a genuine flawless Web service, and current market implementations do not provide adaptable Web service behavior depending on the service contract. This paper proposes two different approaches to increase adaptability of Web services and SOA. The first approach is based on Aspect Oriented Programming (AOP) as a new design solution for Web services. The authors have implemented an infrastructure to enrich services with aspects and to dynamically reroute messages according to changes, without redeployment. The second approach combines Model Driven Development (MDD) and Context-Awareness to promote reuse and adaptability of Web services behavior depending on the service context. Parameterized transformation techniques are proposed to bind context with business logic implemented by a service. The aim is to merge the two approaches to abstract and reduce the technical complexity of aspect based service solution.

The presented approach draws on two main software techniques: Model-Driven Architecture, and aspect-oriented programming. The method involves modeling of the Quality of Service and Extra-functional properties in a platform-independent fashion. Then applying model transformation, the platform-independent models are transformed into platform-specific models, and finally into code. The code for Quality of Service and Extra-functional properties are integrated into the system relying on aspect-oriented techniques in a decoupled manner. The presented approach is evaluated with the help of a case study to establish that the approach results in increasing the system’s modularity and thus reducing implementation and maintenance costs.

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.

As the number of web services is increasing on the web, selecting the proper web service is becoming a more and more difficult task. How to make the selection results from a list of services more customized towards users’ personal preferences and help users identify the right services for their personal needs becomes especially important under this context. In this thesis, we propose a novel User Modeling approach to generate user profiles on their non-functional preferences on web services, and then apply the generated profiles to the ranking process in order to make personalized selection results. The User Modeling system is based on both implicit and explicit information from the user. Also, this is a flexible model to include different types of non-functional properties. We performed experiments using a real web service dataset with values on various non-functional properties to show the accuracy of our system.

The Way

Experts' opinions exist that the way software is built is primitive. The role of modeling as a treatment for Software Engineering (SE) became more important after the appearance of Model-Driven Architecture (MDA). The main advantage of MDA is architectural separation of concerns that showed the necessity of modeling and opened the way for Software Development (SD) to become engineering. However, this principle does not demonstrate its whole potential power in practice, because of a lack of mathematical accuracy in the initial steps of SD. The question about the sufficiency of modeling in SD is still open. The authors believe that SD, in general, and modeling, in particular, based on mathematical formalism in all its stages together with the implemented principle of architectural separation of concerns can become an important part of SE in its real sense. They introduce such mathematical formalism by means of topological modeling of system functioning.

Web services are changing software development thanks to their loosely coupled nature and simple adoption. They can be easily composed to create new more powerful services, allowing for large programming systems. Verification and validation techniques try to find defects in a program to minimize losses that its malfunction could cause. Although many different approaches have been developed for “traditional” program testing, none of them have proven definitive. The problem is even more challenging for new paradigms like web services and web service compositions, because of their dynamic nature and uncommon web service-specific instructions. This chapter surveys the different approaches to web service and web service composition verification and validation, paying special attention to automation. When no tools are available for a given technique, academic efforts are discussed, and challenges are presented.
