“…These tools can be used to build mashup web applications, which have proven to be very useful in the business field as a services integration alternative to rigid SOA architectures, as illustrated by papers like [39,29,30]. There is to date, however, no comparative study analysing the component models implemented by each WEUD tool or proposing a general component model subsuming their functionalities.…”

“…Two lines of thought have attracted similar interest, with research and development papers advocating different courses of action. As some generic EUD applications, like spreadsheets, have been very successful, many researchers advocate setting up a web portal that is general enough to be used to develop solutions for more than one problem domain [1,29,30]. EzWeb, and the proposed model falls into this category.…”

“…These symposiums, together with other international congresses, have promoted several lines of EUD-related investigation akin to the research reported in this paper: (1) attempts at simple programming languages or environments focused on a particular domain, such as EnglishMash (an end user-oriented language with massive natural language use and proactive aids such as autocompleting code) designedbyAghaee and Pautasso [27],orResEval (an EUD environment for mixing R&D domain data sources using a XML-based visual language, which requires knowledge of mark-up languages) created by Muhammad et al [28]; (2) demonstration of the potential of wizard-supported services integration in the EUD field [29,30]; (3) research into human-computer interaction and its particularities in the EUD field, such as [31] stressing how important it is to have user-oriented building blocks in order to focus on solution design rather than the interaction with programming components, or Grudin [32] reporting a study suggesting that HCI consistency is not relevant in the EUD field and can be counterproductive because it hems in user creativity.…”

A B S T R A C TThis paper formally defines a web component model enabling end-user programmers to build component-based rich internet applications (RIAs) that are tailored to meet their particular needs. It is the product of a series of previously published papers. The formal definition in description logic verifies that the model is consistent and subsumes currently existing models. We demonstrate experimentally that it is more effective than the others.Current tools propose very disparate web component models, which are based on the appropriate invocation of service backends, overlooking user needs in order to exploit these services and resources in a friendly manner. We have proposed a web model based on a detailed study of existing tools, their pros and cons, limitations and key success factors that have enabled other web end-user development (WEUD) solutions to help end-user programmers to build software to support their needs. In this paper we have verified that the proposed model subsumes and is instantiated by the models of the other existing tools that we analysed, coming a step closer to the standardization of end-user centred RIAs and development environments. We have implemented a development tool, called EzWeb, to produce RIAs that implement the proposed model. This tool enables users to develop their application following the model's component structure based on end-user programming success factors. We report a statistical experiment in which users develop increasingly complex web software using the EzWeb tool generating RIAs that conform to the proposed component model, and other WEUD tools generating RIAs that conform to other models. This experiment confirms the applicability of the proposed model and demonstrates that more end-user programmers (EUPs) (users concerned with programming primarily for personal rather public use) successfully develop web solutions for complex problems using the EzWeb tool that implements the model, which is more efficient than existing tools that implement other models.

“…The first of these was an investigation of EUSC at the presentation layer, i.e., composition of service interfaces by Nestler et al [9], in which they list 5 general requirements for their tool, the ServFace Builder. Mehandjiev et al [10] present a user-first method for composition. After presenting their composition approach, they provide 6 recommendations gathered from focus groups that were presented with their approach and asked to evaluate it.…”

“…For example, one requirement recommended the use of templates in composition to simplify the process [10]. An important initial design decision was the platform on which the prototype should operate; in our case, the scenario prompted a mobile platform, and Android was selected.…”

End-user Service Composition (EUSC) is defined as service composition where the person who creates the composite service also uses it. We derived requirements for EUSC tools using a custom method based on the scenario-based requirements analysis method. Ten participants were given scenarios, a demonstrator application and examples of EUSC tools before being interviewed. Analysing their responses, we elicited 139 requirements across topics including service ''types'' (e.g. pervasive services), composition flow (i.e. control/data flow) and the use of templates in composition. This is the first published work to have used a robust requirements analysis method in EUSC, adapted specifically to take account of prior work on EUSC. Some of our requirements validate those found in prior research or current EUSC tools but many are unique to our findings. The requirements found in this work inform and inspire the development of future EUSC tools, and the methodology is easily adapted for application in other domains.
