From mashups to telco mashups: A survey

Given their increasing popularity and novel requirements and characteristics, telco mashups deserve an analysis that goes beyond what's available for mashups in general. Here, the authors cluster telco services into different types, analyze their features, derive a telco mashup reference architecture, and survey how well existing mashup tools can respond to these mashups' novel needs. © 2012 IEEE

End-User-Oriented Telco Mashups: The OMELETTE Approach

With the success of Web 2.0 we are witnessing a growing number of services and APIs exposed by Telecom, IT and content providers. Targeting the Web community and, in particular, Web application developers, service providers expose capabilities of their infrastructures and applications in order to open new markets and to reach new customer groups. However, due to the complexity of the underlying technologies, the last step, i.e., the consumption and integration of the offered services, is a non-trivial and time-consuming task that is still a prerogative of expert developers. Although many approaches to lower the entry barriers for end users exist, little success has been achieved so far. In this paper, we introduce the OMELETTE project and show how it addresses end-user-oriented telco mashup development. We present the goals of the project, describe its contributions, summarize current results, and describe current and future work

A user-centric approach to service creation and delivery over next generation networks

Next Generation Networks (NGN) provide Telecommunications operators with the possibility to share their resources and infrastructure, facilitate the interoperability with other networks, and simplify and unify the management, operation and maintenance of service offerings, thus enabling the fast and cost-effective creation of new personal, broadband ubiquitous services. Unfortunately, service creation over NGN is far from the success of service creation in the Web, especially when it comes to Web 2.0. This paper presents a novel approach to service creation and delivery, with a platform that opens to non-technically skilled users the possibility to create, manage and share their own convergent (NGN-based and Web-based) services. To this end, the business approach to user-generated services is analyzed and the technological bases supporting the proposal are explained

A Metadirectory of Web Components for Mashup Composition

Because of the growing availability of third-party APIs, services, widgets and any other reusable web component, mashup developers now face a vast amount of candidate components for their developments. Moreover, these components quite often are scattered in many different repositories and web sites, which makes difficult their selection or discovery. In this paper, we discuss the problem of component selection in Service-Oriented Architectures (SOA) and Mashup-Driven Development, and introduce the Linked Mashups Ontology (LiMOn), a model that allows describing mashups and their components for integrating and sharing mashup information such as categorization or dependencies. The model has allowed the building of an integrated, centralized metadirectory of web components for query and selection, which has served to evaluate the model. The metadirectory allows accessing various heterogeneous repositories of mashups and web components while using external information from the Linked Data cloud, helping mashup development

Towards automated composition of convergent services: a survey

A convergent service is defined as a service that exploits the convergence of communication networks and at the same time takes advantage of features of the Web. Nowadays, building up a convergent service is not trivial, because although there are significant approaches that aim to automate the service composition at different levels in the Web and Telecom domains, selecting the most appropriate approach for specific case studies is complex due to the big amount of involved information and the lack of technical considerations. Thus, in this paper, we identify the relevant phases for convergent service composition and explore the existing approaches and their associated technologies for automating each phase. For each technology, the maturity and results are analysed, as well as the elements that must be considered prior to their application in real scenarios. Furthermore, we provide research directions related to the convergent service composition phases

Enterprise Mashups: A New Approach for Business Solutions

A mashup is a Web application that integrates content from different providers in order to create a new service which is not offered by the content provider. The development of this kind of applications involves activities such as accessing heterogeneous sources, combining data from different data sources and building graphical interfaces. This factor limits non-experienced computer users to develop these applications. However, nowadays there are enterpriseoriented tools that allow non-experienced user for building mashups in order to respond business needs in an easy and rapid way. Due to this, the enterprise mashup approach has been widely adopted by a large number of enterprises. This paper presents an overview of the enterprise mashup approach, as well as a review of four enterprise-oriented tools which provide a set of features that allows non-expertise users developing mashups into an enterprise. Finally, we present the challenges to be addressed by enterprise-oriented mashup tools in order to provide an easier and faster way of developing mashups

Challenges for the comprehensive management of cloud services in a PaaS framework

The 4CaaSt project aims at developing a PaaS framework that enables flexible definition, marketing, deployment and management of Cloud-based services and applications. The major innovations proposed by 4CaaSt are the blueprint and its lifecycle management, a one stop shop for Cloud services and a PaaS level resource management featuring elasticity. 4CaaSt also provides a portfolio of ready to use Cloud native services and Cloud-aware immigrant technologies

Interactive, live mashup development through UI-oriented computing

This paper proposes to approach the problem of developing mashups by exclusively focusing on the SurfaceWeb, that is, the data and functionality accessible through common Web pages. Typically, mashups focus on the integration of resources accessible through the Deep Web, such as data feeds, Web services and Web APIs, that do not have own UIs – next to data extracted from Web pages. Yet, these resources can be wrapped with ad-doc UIs, suitably instrumented, and made accessible through the Surface Web. Doing so enables a UI-oriented computing paradigm that allows developers to implement mashups interactively and in a live fashion inside theirWeb browser, without having to program any line of code. The goal of this paper is to showcase UI-oriented computing in practice and to demonstrate its feasibility and potential
