The MK Data Hub is the technical, data infrastructure of the MK:Smart project, supporting the collection, integration and use of large amounts of data from many diverse resources relevant to city systems.The datasets include local and national open data, data streams from both key infrastructure networks (energy, transport, water) and other relevant sensor networks (e.g., weather and pollution data), data crowdsourced from social media and mobile applications, etc.As a data platform for the city, the MK Data Hub enables the onboarding of data from data providers, who remain in control of the redistribution policies (the data licences) and the access permissions they want to apply. The data catalogue supports the discovery of the data, as well as the description and traceability of the relevant metadata, such as the sources and rights that apply to the data.Much of the functions of the MK Data Hub are centred around smart APIs (Application Programming Interfaces) to re-deliver the data in a common, homogeneous and convenient way for the developers of data-intensive applications (see developer section of the MK Data Hub portal).
Currently, the MK Data Hub includes a streaming API for timeline and sensor data, and an Entity API which aggregates the information available in the hub on general entities (places, buildings, topics, etc.) from the many datasets contributing to the MK Data Hub .These data and APIs are used to inform analytics at different levels of detail to support intelligent planning and usage of resources across city systems. Innovative solutions are being created using the MK Data Hub to reduce the cost of data-driven application development.
