This work pursues the challenge of achieving effective citizen collaboration by empowering them to prosume urban data across time. Particularly, this paper focuses on the query mapper; a key component of the IES Cities platform devised to democratize the development of open data-based mobile urban apps. This component allows developers not only to use available data, but also to contribute to existing datasets with the execution of SQL sentences. In addition, the component allows developers to create ad hoc storages for their applications, publishable as new datasets accessible by other consumers. As multiple users could be contributing and using a dataset, our solution also provides a data level permission mechanism to control how the platform manages the access to its datasets. We have evaluated the advantages brought forward by IES Cities from the developers' perspective by describing an exemplary urban app created on top of it. In addition, we include an evaluation of the main functionalities of the query mapper.5155335enginfo:eu-repo/semantics/openAccessjournal article10.3390/s16071022smart cityappsheterogeneous dataprosumingaccess controlsmart cityappsheterogeneous dataprosumingaccess controlAnalytical ChemistryBiochemistryAtomic and Molecular Physics, and OpticsInstrumentationElectrical and Electronic EngineeringSDG 11 - Sustainable Cities and CommunitiesFunding InfoEuropean Union's Competitiveness and Innovation Framework Programme (ICT-PSP CIP Programme).
