Open Urban Sensor Data Platform as enabler for reuse and repurpose

Within SINFONIA, up to ten Smart Value Added Service are defined aiming at allowing the development of a respective business case for existing service providers as well as to create new business. Here, one key aspect is to combine the knowledge provided by different sensor systems as well as different data sources, so like utilities information on the current grid state. As connecting and combining those different data sources is particularly challenging, we point out a solution how to enable the reuse and repurposeof data sources using an open sensor data platform.

Living spaces are never finished: A location may keep a given configuration for a while, but like any human space, it is subject to changes and mutations of its purposes and composition, as people shape their places according to their needs. In SINFONIA, we tackle these challenges with an open urban sensor data platform that expects changes, and knows about binding and rebinding systems for different people across different processes and spaces. With the platform, we can connect the existing data sources as well as new ones. Devices from different suppliers will form a software – integrated information pool that can be used in different applications. On the platform, information is homogenized from the different data sources on a common schema.

One-to-one relations between sensors and endpoints break up: Different analytics modules and event processing makes it configurable for stakeholders to define abstraction levels like aggregations, based on time and space. So, building up new business cases does not longer depend on bringing out new infrastructure, but build on existing one by reuse and repurposing of sensor data.

Using an open urban sensor data platform, it is possible to provide cross – domain real-time data for different applications on top of the platform. Platform – side abstraction enables to provide data to different stakeholders at the same time. As providers can define for themselves which of their data is accessible for whom and at which abstraction level, the systems can act according to Austrian data protection laws. By that, measurement data can be reused and repurposed, independent of the different systems the data comes from.

Lessons learnt:
Lots of suppliers do not follow an open philosophy today. To correspond to this, special connectors need to be developed, to bring this data on the platform, what may need a considerable amount of time. Nevertheless, by providing software SDKs, this will be speed up son to enable also rapid connections of proprietary systems.
