ABSTRACT
This chapter describes the data processing supported by the GAMBAS middleware. Towards this end, the chapter first describes the formalisms and ontologies for the data and query models. The formalisms and ontologies provide a unified view of the heterogeneous data produced by the different players in the targeted applications. Such a unified view, based on semantic descriptions of the data and the data sources, is in line with the linked data paradigm, and it not only facilitates data understanding, but also improves data discovery and integration between both objects and persons, and other sources of data that follows the same paradigm, such as the Web of Data. Based on the data and query models, the chapter introduces the general data discovery mechanisms that are used to make data available to others. Finally, the chapter describes the architecture and implementation of the distributed data storage and processing system that allows devices to cooperate with each other in a seamless and interoperable way.
