Currently, the majority of the world population lives in cities encouraging different stakeholders within these innovative ecosystems to seek new solutions guaranteeing the sustainability and efficiency of such complex environments. In this work, it is discussed how the experimentation with IoT technologies and other data sources form the cities can be utilized to co-create in the OrganiCity project, where key actors like citizens, researchers and other stakeholders shape smart city services and applications in a collaborative fashion. Furthermore, a novel architecture is proposed that enables this organic growth of the future cities, facilitating the experimentation that tailors the adoption of new technologies and services for a better quality of life, as well as agile and dynamic mechanisms for managing cities. In this work, the different components and enablers of the OrganiCity platform are presented and discussed in detail and include, among others, a portal to manage the experiment life cycle, an Urban Data Observatory to explore data assets, and an annotations component to indicate quality of data, with a particular focus on the city-scale opportunistic data collection service operating as an alternative to traditional communications.<\/jats:p>","DOI":"10.3390\/s16111971","type":"journal-article","created":{"date-parts":[[2016,11,23]],"date-time":"2016-11-23T11:12:14Z","timestamp":1479899534000},"page":"1971","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":43,"title":["Co-Creating the Cities of the Future"],"prefix":"10.3390","volume":"16","author":[{"given":"Ver\u00f3nica","family":"Guti\u00e9rrez","sequence":"first","affiliation":[{"name":"Communications Department, University of Cantabria, Santander 39005, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Evangelos","family":"Theodoridis","sequence":"additional","affiliation":[{"name":"INTEL Labs Europe, London SW7 2AZ, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2128-720X","authenticated-orcid":false,"given":"Georgios","family":"Mylonas","sequence":"additional","affiliation":[{"name":"Computer Technology Institute and Press, \u201cDiophantus\u201d, Patras 26504, Greece"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fengrui","family":"Shi","sequence":"additional","affiliation":[{"name":"Department Computing, Imperial College London, London SW7 2AZ, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Usman","family":"Adeel","sequence":"additional","affiliation":[{"name":"INTEL Labs Europe, London SW7 2AZ, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5817-3308","authenticated-orcid":false,"given":"Luis","family":"Diez","sequence":"additional","affiliation":[{"name":"Communications Department, University of Cantabria, Santander 39005, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dimitrios","family":"Amaxilatis","sequence":"additional","affiliation":[{"name":"Computer Technology Institute and Press, \u201cDiophantus\u201d, Patras 26504, Greece"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Johnny","family":"Choque","sequence":"additional","affiliation":[{"name":"Communications Department, University of Cantabria, Santander 39005, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Guillem","family":"Camprodom","sequence":"additional","affiliation":[{"name":"Institute for Advanced Architecture of Catalonia (IAAC), Barcelona 08005, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Julie","family":"McCann","sequence":"additional","affiliation":[{"name":"Department Computing, Imperial College London, London SW7 2AZ, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Luis","family":"Mu\u00f1oz","sequence":"additional","affiliation":[{"name":"Communications Department, University of Cantabria, Santander 39005, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2016,11,23]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"World Health Organization (2010).
