Km4City ontological model and data aggregation of 2014 [Bellini et al., 2014b] with its Smart City API, has been recently augmented with results of the Sii-Mobility project on mobility and transport. Thus, it enables the development and deploy of personal assistant services, for example to implement Mobile Apps for city users with multi-domain information, and at the same time collects data from the users about their preferences and behavior. Km4City can be adopted by city operators and industries to create web and mobile applications, and to exploit published/integrated open and private data, static and real time data. On the other hand, it can be easily extended and applied to different Smart Cities.
The following is a list of historical changes that were made to this asset. Typically, once an API is published on ProgrammableWeb.com, the data we keep about that asset gets updated over the course of its life. For example, the endpoint or home page of the documentation might change. As a means of enforcing the integrity of our data, every time a non-trivial change is made to the data we keep about an asset, we require the entry of some changelog text before that change can be saved. This way, we have a great audit trail of all activity surrounding the asset. For each asset, the changelogs begins with the moment an asset is approved for publication on ProgrammableWeb. If you spot an error in our data and believe that a record needs to be updated in some way, the ProgrammableWeb team would very much like to hear from you at firstname.lastname@example.org
