“…In order to overcome this drawback, EFESTO provides a polymorphic data source that exploits the wide availability of information published in the Linked Open Data (LOD) cloud. It is called polymorphic because, when it is composed with another source S, it can dynamically adapt the set of exposed attributes depending on the source S, so that a "navigation" from the source S to the polymorphic data source is possible [16].…”

Developing interactive systems to access and manipulate data is a very tough task. In particular, the development of user interfaces (UIs) is one of the most time-consuming activities in the software lifecycle. This is even more demanding when data have to be retrieved by accessing flexibly different online resources. Indeed, software development is moving more and more toward composite applications that aggregate on the fly specific Web services and APIs. In this article, we present a mashup model that describes the integration, at the presentation layer, of UI components. The goal is to allow non-technical end users to visualize and manipulate (i.e., to perform actions on) the data displayed by the components, which thus become actionable UI components. This article shows how the model has guided the development of a mashup platform through which non-technical end users can create component-based interactive workspaces via the aggregation and manipulation of data fetched from distributed online resources. Due to the abundance of online data sources, facilitating the creation of such interactive workspaces is a very relevant need that emerges in different contexts. A utilization study has been performed in order to assess the benefits of the proposed model and of the Actionable UI Components; participants were required to perform real tasks using the mashup platform. The study results are reported and discussed.

“…In fact, this mash-up platform allows end users to extend a Web service with the so-called "polymorphic data source" built on top of the Linked Open Data cloud. It is called polymorphic because it provides mutable information with respect to the data sources of which it is composed [Desolda, 2015].…”

New Perspectives in End-User Development

Our contribution will review, analyze, discuss, and synthesize the research work done over the last 10 years exploring meta-design as a major framework for end-user development (EUD). The overriding perspective of our approach is grounded in the basic assumptions that (1) designers can prompt and support change in a community of practice, but they cannot predetermine it and (2) design and use mutually shape one another in iterative, social processes. The chapter argues and provides evidence that EUD should not be restricted to create new technologies but its most important and far-reaching impact will be to transform cultures by empowering all people to become active contributors in personally meaningful activities. The individual sections discuss and describe our basic framework, EUD applications in different domains, new conceptual developments that broadened the concept of meta-design, the identification of design trade-offs and drawbacks, and design guidelines. All of these activities have contributed to revisiting and broadening the meta-design framework for end-user development

“…In our previous work, we defined paradigms and related platforms for the EUD of Web mashups. In particular, we investigated how data provided by Web APIs could be integrated into unified visualizations [Desolda 2015;Desolda et al 2016], and how such visualizations could be synchronized at the presentation level by means of an event-driven technique [Cappiello et al 2015;Cappiello et al 2011]. Through visual editors, end users were enabled to build interactive Web applications synchronizing the behavior of different visual components.…”

Research on the Internet of Things (IoT) has devoted many efforts to technological aspects. Little social and practical benefits have emerged so far. IoT devices, so-called smart objects , are becoming even more pervasive and social, leading to the need to provide non-technical users with innovative interaction strategies for controlling their behavior. In other words, the opportunities offered by IoT can be amplified if new approaches are conceived to enable non-technical users to be directly involved in “composing” their smart objects by synchronizing their behavior. To fulfill this goal, this article introduces a model that includes new operators for defining rules combining multiple events and conditions exposed by smart objects, and for defining temporal and spatial constraints on rule activation. The article also presents the results of an elicitation study that was conducted to identify possible visual paradigms for expressing composition rules. Prototypes implementing the resulting visual paradigms were compared during a controlled experiment and the one that resulted most relevant for our goals was used in a study that involved home-automation experts. Finally, the article discusses some design implications that came out from the performed studies and presents the architecture of a platform supporting rule definition and execution.
