Programming patterns and development guidelines for Semantic Sensor Grids (SemSorGrid4Env)

The web of Linked Data holds great potential for the creation of semantic applications that can combine self-describing structured data from many sources including sensor networks. Such applications build upon the success of an earlier generation of 'rapidly developed' applications that utilised RESTful APIs. This deliverable details experience, best practice, and design patterns for developing high-level web-based APIs in support of semantic web applications and mashups for sensor grids. Its main contributions are a proposal for combining Linked Data with RESTful application development summarised through a set of design principles; and the application of these design principles to Semantic Sensor Grids through the development of a High-Level API for Observations. These are supported by implementations of the High-Level API for Observations in software, and example semantic mashups that utilise the API

MockupDD: Facilitating agile support for Model-Driven Web Engineering

Model-Driven Web Engineering methodologies provide a more productive way of building Web Applications using high-level models and generating final implementations from them. However, they follow a waterfall-like development process, forcing to specify a different set of models sequentially to obtain a first runnable prototype of the Web Application. On the other hand, agile methodologies pursue an iterative process based on the delivery of application prototypes in short periods of time using manual coding, which results less productive and more error-prone in comparison to model-based approaches. In this work we propose a hybrid agile and Model-Driven approach called MockupDD that intends to blend the best of MDWE and agile development processes.Publicado en Lecture Notes in Computer Science book series (LNCS, vol. 8295).Laboratorio de Investigación y Formación en Informática Avanzad

Building dynamic WAP applications using UWE

The great advance of the communications and the importance gained by the mobile systems have increased the development of WAP (Wireless Application Protocol) applications, nevertheless at the present time do not exist methodologies specifically designed for the WAP applications development process. However, in the last years, several methodologies for the web applications development process have been proposed. One of them is UWE (UML-based Web Engineering) [1]. Although this methodology has specifically been developed for web applications, the similarity between web and WAP systems allows us to propose the use of it, to generate a design stage approach for WAP applications and then to create a specific extension of UWE to build WAP applications. In order to obtain this, we present a new UWE based model called WAP navigational model for the navigational design and presentational design steps, which we can use to design WAP systems improving the WAP applications development process.Eje: I - Workshop de Ingeniería de Software y Base de DatosRed de Universidades con Carreras en Informática (RedUNCI

Bridging test and model-driven approaches in web engineering

In the last years there has been a growing interest in agile methods and their integration into the so called "unified" approaches. In the field of Web Engineering, agile approaches such as test-driven development are appealing because of the very nature of Web applications, while model-driven approaches provide a less error-prone code derivation; however the integration of both approaches is not easy. In this paper, we present a method-independent approach to combine the agile, iterative and incremental style of test-driven development with the more formal, transformation-based model-driven Web engineering approaches. We focus not only in the development process but also in the evolution of the application, and show how tests can be transformed together with model refactoring. As a proof of concept we show an illustrative example using WebRatio, the WebML design tool.Publicado en Lecture Notes in Computer Science book series (LNCS, vol. 5648).Laboratorio de Investigación y Formación en Informática Avanzad

25 Years of Model-Driven Web Engineering : What we achieved, what is missing

Model-Driven Web Engineering (MDWE) approaches aim to improve the Web applications development process by focusing on modeling instead of coding, and deriving the running application by transformations from conceptual models to code. The emergence of the Interaction Flow Modeling Language (IFML) has been an important milestone in the evolution of Web modeling languages, indicating not only the maturity of the field but also a final convergence of languages. In this paper we explain the evolution of modeling and design approaches since the early years (the 90’s) detailing the forces which drove that evolution and discussing the strengths and weaknesses of some of those approaches. A brief presentation of IFML is accompanied with a thorough analysis of the most important achievements of the MDWE community as well as the problems and obstacles that hinder the dissemination of model-driven techniques in the Web engineering field.Laboratorio de Investigación y Formación en Informática Avanzada (LIFIA

Agile Based Development Methodology for Mobile Commerce Applications

There are several system development methodologies including traditional and agile methodologies which are being utilized in current systems development. However, it could be argued that existing methodologies may not be suitable for the development of mobile commerce applications as these applications are utilized in different contexts from conventional fixed e-commerce applications such as they are displayed on a small screen device, they are utilized in an unstable or movable environment and they need to be used in a secured environment to deliver financial transactions over mobile network. This study aimed to construct an agile based development methodology for mobile commerce applications. In order to achieve this aim, three objectives have been proposed including identification of essential issues for developing m-commerce applications, construction of a predictable agile based methodology used for developing m-commerce applications and evaluation for its applicability and practicality. The research methodology used in the study is the design research, which include the steps of awareness of problems, suggestion, development, evaluation and conclusion. The research methods used to assist the mentioned research methodology include literature analysis, industry visits, semi-structured interview, survey, formulative research and experimental evaluation. The methodology constructed contains the integration of essential factors in each phase of systems development life cycle as well as guidelines to follow for conducting activities in the application development, including specific models, tools, and techniques. From the evaluation of the constructed methodology, the results showed two essential outcomes. Firstly, the constructed methodology is applicable as it can be used to build the intended system, mobile commerce applications in this case. Secondly, for practicality, it showed that the constructed methodology is practical as when comparing to the traditional waterfall development by using the eleven measurements specified, it exposed more benefits to the development process
