The benefits of incorporating Semantic Web Services in web applications are well documented. However, both the real-world implementation and adoption of these services are still rather limited in practice. This is despite the promises that extend syntactic Web services with capabilities such as automatic service discovery, composition, and execution. Some of the barriers to the real-world implementation are the complexities and tool support related to the development of Semantic Web Services. In this article, the main challenge that is addressed is the tight coupling of existing Semantic Web Services (SWS) development platforms to specific semantic description languages and service description languages, which unintentionally lead to unbending service development environments. The main contribution in this article is therefore a model-driven approach called iSemServ that exploits mature technologies, such as UML, and model-transformation techniques for simplifying and semi-automating the development of SWS using description languages of choice, such as Web Ontology Language for Services (OWL-S) and Web Application Description Language (WADL). A design science research methodology was employed in conducting the study. The suggested approach was practically implemented as an Eclipse plug-in and evaluated based on a real-world use case scenario and comparative analysis of related solutions. The evaluation results show that our proposed solution is relevant and appropriate in aiding the semi-automatic development of SWS, albeit with a number of limitations that could be addressed by extending the proposed practical solution.

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.

This chapter introduces the emerging technology of Semantic Web services. It concentrates on two dominant specifications in this domain, namely OWL-S (Web ontology language for services) and WSMO (Web services modeling ontology). We briefly introduce Web services and Semantic Web, two main technologies underlying the Semantic Web services technology and then explain most of the key features of this technology together with simplified examples. We discuss three aspects of Semantic Web services: specifications for semantic descriptions of services, intelligent discovery and selection of services using semantic descriptions, and finally, building more complex services by composing existing ones. Our main goal in this chapter is not only to present an abstract view of this technology but also the introduction of the technical details of the two existing specifications.

Much of the early focus in the area of Semantic Web has been on the development of representation languages for static conceptual information; while there has been less emphasis on how to make Semantic Web applications practically useful in the context of knowledge work. To achieve this, a better coupling is needed between ontology, service descriptions, and workflow modeling, including both traditional production workflow and interactive workflow techniques. This chapter reviews the basic technologies involved in this area to provide system and business interoperability, and outlines what can be achieved by merging them in the context of real-world workflow descriptions.
