Abstract:Mashups that combine already existing data into an integrated experience are becoming increasingly popular. So far most mashups have been built around maps and images. However, as the web is becoming an increasingly ubiquitous media, also multimedia content -sound, video and even small programs -is emerging as a candidate for mashup creation, with potentially superior user experience. Currently available methods to implement mashups do not allow effortless access to personal data across domains or provide mean… Show more
“…They are seen as an important value-delivery vehicle for OGD, translating raw data into useful information and thereby "bringing out the full potential of open government data" (DiFranzo et al, 2011, p. 206). They may create innovative new services and/or present data in new and unforeseen ways (Beemer and Gregg, 2009;Salminen, Kallio, and Mikkonen, 2011;Wakaruk, 2013). Value may be created by providing context and meaning that is relevant to the individual user (DiFranzo et al, 2011).…”
The open government paradigm relies on the provision and reuse of open government data (OGD) to improve transparency and create new sources of value. This study aims to progress understanding of OGD beyond a theoretical commentary by exploring the perceived sources of value of mashups (online services that combine diverse OGD), and to examine issues that impact on, and facilitate, the delivery of this value from an 'insider' perspective. Based on open-ended interviews with 17 individuals actively involved in OGD application design, use, and advocacy in New Zealand (ranked fourth in the 2013 Global Open Data Barometer) nine key sources of value were identified: Ease of discovery, improved data quality, bringing knowledge into relevant contexts, economic benefits, social benefits, cost reduction and efficiencies, predictive value, transparency, and ability to explore and play. Twelve barriers to delivering this value were found, ranging from change-related issues to problems relating to sustainability. Six facilitators were identified as helping to overcome these barriers and realise the value of OGD.

Accessing private and public multimedia content over the web with mobile terminals can be cumbersome. To approach this problem, we introduce an ecosystem where the content is accessed with clients that are constructed as mashups. Mashups are web applications that combine already existing data into an integrated experience. In addition to traditional mashup elements such as text and images, also other types of multimedia artifacts -sound, video and even small programs -can be used as content in mashups. However, currently available methods implementing mashups do not allow effortless access to personal data across domains or provide means to ensure that the user experience is coherent. This paper describes our mobile mashup architecture aimed to solve these problems and work as a ubiquitous platform for mobile multimedia mashups. The architecture enables a mashup ecosystem where different content providers and client developers can contribute. As a practical implementation, we present a video mashup client developed for Android. In addition, we discuss the lessons learned during the research.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
