Ten Years of Rich Internet Applications

Abstract

BACKGROUND. The term Rich Internet Applications (RIAs) is generally associated with Web applications that provide the features and functionality of traditional desktop applications. Ten years after the introduction of the term, an ample amount of research has been carried out to study various aspects of RIAs. It has thus become essential to summarize this research and provide an adequate overview. OBJECTIVE. The objective of our study is to assemble, classify, and analyze all RIA research performed in the scientific community, thus providing a consolidated overview thereof, and to identify well-established topics, trends, and open research issues. Additionally, we provide a qualitative discussion of the most interesting findings. This work therefore serves as a reference work for beginning and established RIA researchers alike, as well as for industrial actors that need an introduction in the field, or seek pointers to (a specific subset of) the state-of-the-art. METHOD. A systematic mapping study is performed in order to identify all RIA-related publications, define a classification scheme, and categorize, analyze, and discuss the identified research according to it. RESULTS. Our source identification phase resulted in 133 relevant, peer-reviewed publications, published between 2002 and 2011 in a wide variety of venues. They were subsequently classified according to four facets: development activity, research topic, contribution type, and research type. Pie, stacked bar, and bubble charts were used to depict and analyze the results. A deeper analysis is provided for the most interesting and/or remarkable results. CONCLUSION. Analysis of the results shows that, although the RIA term was coined in 2002, the first RIA-related research appeared in 2004. From 2007 there was a significant increase in research activity, peaking in 2009 and decreasing to pre-2009 levels afterwards. All development phases are covered in the identified research, with emphasis on “design” (33%) and “implementation” (29%). The majority of research proposes a “method” (44%), followed by “model” (22%), “methodology” (18%), and “tools” (16%); no publications in the category “metrics” were found. The preponderant research topic is “models, methods and methodologies” (23%) and, to a lesser extent, “usability and accessibility” and “user interface” (11% each). On the other hand, the topic “localization, internationalization and multilinguality” received no attention at all, and topics such as “deep Web” (under 1%), “business processing”, “usage analysis”, “data management”, “quality and metrics” (all under 2%), “semantics”, and “performance” (slightly above 2%) received very little attention. Finally, there is a large majority of “solution proposals” (66%), few “evaluation research” (14%), and even fewer “validation” (6%), although the latter have been increasing in recent years.

Leveraging declarative languages in web application development

“…Based on two recent surveys [10,54], we identify WebML-RIA [7,15] as being closest to XFormsDB, and thus provide a thorough comparison between these two approaches. Finally, we discuss the differences between declarative and imperative Web Application development.…”

“…Another recent survey [10] shows that research focuses on either model-driven design or implementation issues-a distinct gap exists between them. In this paper, we propose that a single, declarative model is used both on the client-side (i.e., presentation tier) and server-side (i.e., logic and data tiers); including client-server communication and interaction.…”

Improving accessibility of CMS-based websites using automated methods

“…Websites have been made up of a static HTML pages for a long time. Nowadays, web developers often use various toolkits and frameworks that are created using sophisticated development tools [7]. However, the amount of development techniques available is huge, furthermore the rapid changes in technology makes it difficult to follow developments [8].…”

A Mechanism for Identifying Dynamic Components in Rich Internet Applications

“…In this scenario, there was the emergence of Rich Internet Applications (RIAs). RIAs are characterized as Web applications that aim to provide resources and functionality, providing a user experience similar to traditional Desktops applications [3].…”
