“…The Snap4City platform [39] provides a centralized architecture in which geographical and statistical data from different sources is collected to enable developers to create LBS. The platform uses the Km4City multiontology [40] to represent geographical information using a common metamodel. As in the previous case, the main difference with our system is the decentralized architecture presented in this paper.…”

Location-Based Services (LBS) are attracting a great interest with the fast expansion of mobile computing nowadays. These services use the user location to customize the offered information. However, most of those services are designed for specific scenarios and goals with implicit knowledge about the application context. As a consequence, hundreds of them are available (even with the same purpose). So, it is difficult for users to choose the most suitable service as they are in charge of knowing/finding the services which will be interesting for them, and handle the information that such services need. In this paper, we present an approach to handle LBS for mobile users which relieves them from knowing and managing the knowledge related to such services. This approach consists of a proposal for the modeling of such information as ontologies, which are handled by an agent-based architecture. Also, we propose to maintain updated the knowledge each mobile device contains by leveraging the exchange of information with others. For accessing the local knowledge, we present an SPARQL-like query language which avoids the ambiguities of natural language. Finally, we propose an approach to translate the user information needs into formal requests expressed in this query language, which could be later processed against the knowledge repositories to obtain the results the user needs.

“…It includes multi-sourced data concerning place, time, and people concepts, categorized in utilization, activity, opinion, and sensing parameters [14]. As another example, the researchers from Distributed Systems and Internet Technologies Laboratory (2015) develop a knowledge model for the city (Km4City) [15]. Nesi and others [15] state that Km4City brings a new approach to smart city APIs.…”

“…In some case these IoT Applications can make use of External Services provided by a set of MicroServices exposed by the platform: they are accessed remotely via Internet connection and clearly in case the connectivity is not available or guarantee, the application logic has to treat this kind of information according to a backup ad-hoc solution. The MicroServices are implemented using the Smart City API [11] that work directly on top of a Km4City based Knowledge Base (KB) and a Data Shadowing system. A set of additional tools are also available; for simplicity here just two main macro-blocks are presented: the analytics set of tools and the scheduling functionality.…”

Internet of Things paradigm enables computation and communication in tools that every day everyone uses. The vastness and heterogeneity of devices and the ways they are composed to offer innovative services and scenarios require a challenging vison in interoperability, security and in managing huge quantity of data. Many IoT frameworks and platforms propose to solve these issues, aggregating different sources of information and combine their flow of data in innovative services. Due to the potentially very sensible nature of some of this data, privacy and security aspects have to be taken into account by design and by default. An end-to-end secure solution has to permit the final users to have full control on their personal data and, on the other side, the framework has to support developers in writing applications offering the highest level of security/protection on their data flow. European Commission GDPR also added complexity to this context. In this paper, Snap4City solution to support such level of privacy and security in an IoT scenarios is presented. Snap4City has been developed in the context of Select4Cities PCP project of the European Commission.
