iQueue: A pervasive data composition framework

There will soon be a huge number of data sources accessible to applications across the Internet. These include web services, personal devices such as cellular phones and cars, and sensors measuring physical phenomena. New classes of data-composition applications can exploit this data. However, the data is diverse, voluminous, and often rapidly changing. The sources of the data can be mobile, distributed, and failure-prone. Without system support, applications that use this kind of data are difficult to write. The Queue data composition framework provides system support for data composition, thereby making the task of writing applications easier.
