This process is translated into the Open Standardized Urban Data Platform, which plays a pivotal role. Within its main functionalities, data ingestion, analytics and services as vertical domains become necessary to create more environmentally friendly cities. However, there still exist some deficits. Among them, openness and interoperability are outlined. On the one hand, there is a lack of open data initiatives for increasing the smart services stock. On the other hand, interoperability depends upon vendors and integrators, reducing the possibilities of Smart City growth. In this context, under the mySMARTLife project (GA #731297) umbrella, an Open Specifications Framework has been developed in order to address four main issues: (1) data interoperability; (2) services or verticals interoperability; (3) openness; and (4) replicability. It enlightens the implementation and integration of multiple city domains (like infrastructures, mobility, energy, buildings) for smart management and big-data analytics. Its applicability is demonstrated in the three lighthouse cities of the project, Nantes (France), Hamburg (Germany) and Helsinki (Finland).<\/jats:p>","DOI":"10.3390\/s20082402","type":"journal-article","created":{"date-parts":[[2020,4,23]],"date-time":"2020-04-23T10:46:22Z","timestamp":1587638782000},"page":"2402","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":33,"title":["Interoperable Open Specifications Framework for the Implementation of Standardized Urban Platforms"],"prefix":"10.3390","volume":"20","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7621-2937","authenticated-orcid":false,"given":"Jos\u00e9 L.","family":"Hern\u00e1ndez","sequence":"first","affiliation":[{"name":"CARTIF Foundation\u2014Energy Division, Parque Tecnol\u00f3gico Boecillo, 205, 47151 Boecillo, Spain"}]},{"given":"Rub\u00e9n","family":"Garc\u00eda","sequence":"additional","affiliation":[{"name":"CARTIF Foundation\u2014Energy Division, Parque Tecnol\u00f3gico Boecillo, 205, 47151 Boecillo, Spain"}]},{"given":"Joachim","family":"Schonowski","sequence":"additional","affiliation":[{"name":"Freelancer (Avoid Reduce Reuse)\u2014Digital Expert on Smart Cities (T-Labs during mySMARTLife), Rietze Strasse, 10409 Berlin, Germany"}]},{"given":"Daniel","family":"Atlan","sequence":"additional","affiliation":[{"name":"ENGIE INEO Solutions Digitales, Rue Henri Farman, 86, 92130 Issy-les-Moulineaux, France"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1927-7355","authenticated-orcid":false,"given":"Guillaume","family":"Chanson","sequence":"additional","affiliation":[{"name":"Nantes M\u00e9tropole, Cours du Champ de Mars, 2, 44923 Nantes, France"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1268-1897","authenticated-orcid":false,"given":"Timo","family":"Ruohom\u00e4ki","sequence":"additional","affiliation":[{"name":"Forum Virium Helsinki, Unioninkatu, 24, 00130 Helsinki, Finland"}]}],"member":"1968","published-online":{"date-parts":[[2020,4,23]]},"reference":[{"key":"ref_1","unstructured":"(2019, January 15).
