Collaborative development of trusted mashups

Purpose - The purpose of this paper is to identify the gap that currently exists between enterprise and consumer‐focused mashup tools in terms of personalized, trusted collaboration. The authors describe how Sqwelch, a semantically enabled mashup maker, addresses this gap during the design of mashups and in their execution. Design/methodology/approach - Sqwelch enables the composition of mashups based on the concept of trust explicitly specified by users through a visual interface. Taxonomies are used to enable lightweight mediation of payloads delivered through a publish/subscribe mechanism. Findings - The authors demonstrate the use of Sqwelch as a proof of concept in the remote delivery of healthcare, and how Sqwelch has been used to address areas of trust and collaboration in the delivery of telehealth services. Originality/value - Integrating trust and collaboration across the boundaries of enterprises is required where sensitive data are transferred across those boundaries in the expectation of the delivery of a service. Across these boundaries, the authors find variations in users' skills, their expectations, and their responsibilities. The prototype described here enables users to discover, compose, share and collaborate in the day‐to‐day use of systems that match personalized requirements.
