Design and specifications of a repository for real-time open data

Real-time data generated by the many sensors and other sources today can serve as important input to mobile and web applications. This data, however, is often either proprietary or in a format that is not easily usable by real time applications. Furthermore, if an application developer needs to integrate (mash-up) data from multiple sources it is quite burdensome to develop interfaces. The present platforms for open data repositories are designed for static non real-time data. We propose a design and specifications for a platform that will accept real-time open data from multiple sources in multiple formats and make the data accessible in a standard format at any desired frequency. The data is held for a finite period of time (depending on factors such as frequency, precision, etc.) and digests made so that developers can also make use of historical data.
