Particularly, it focuses on the Query Mapper, a key component of this platform devised to democratize the development of Open Data based mobile urban apps. The advantages from the developers’ perspective brought forward by IES Cities are evaluated by describing an exemplary urban app created on top of it. This work pursues the challenge of achieving effective citizen collaboration by empowering them to prosume urban data across time.12606981enginfo:eu-repo/semantics/restrictedAccessconference output10.1007/978-3-319-26401-1_19Smart CityLinked DataAppsCrowdsourcingHTML5Smart CityLinked DataAppsCrowdsourcingHTML5Theoretical Computer ScienceGeneral Computer ScienceSDG 11 - Sustainable Cities and CommunitiesFunding InfoEuropean Commission´s Competitive and Innovation Programme.
